Here's a good article to read as reference to the topics in this video thanks for watching!!! www.airgundepot.com/vault/articles/all-about-ballistic-coefficient/
Your science is off. In order to have a valid expirament to find BC the weight and velocity at the muzzle must match. BC tells the difference between same weight projectiles slowing down during flight. All bullets fall at the same speed 9.8Ms_2.
BC and drop are not directly related. Drop is a result of gravity acting on the projectile. So if you shoot a projectile with a lower speed, it will drop more during its flight than a faster projectile, simply because gravity has more time to act upon it. High BC projectiles retain more speed so they cover the distance faster, compared to projectile with the same muzzle velocity. (thus minimizing the effect of gravity.)
Correct drop is purely a product of velocity and time in the air the gravity is consistent. I would word the high BC as they retain their speed better so if they start slower they overtake at some point down range, so long range they will cover the distance faster but close range it's whatever is fastest.
Can I ask a newbie type question with regards to pellets and slugs. If you zero at 100 yds for both does that mean that each will be zero from 0 to 100 yds?
@@jackbisson9226 maybe, if you pellet and slug have the same BC, yes. But generally we shoot slug because they have a higher BC, so your slugs will drop less than your pellets. So if you zero slugs at a 100, your pellets will be zero'ed at maybe 80ish yards
The slug is heavier so with the same setting you are shooting it slower. As a result, it will drop more over the same distance because its travelling for a longer period of time. The higher BC of the slug means it will lose less of its total velocity over a given distance compared to a pellet which is predominately drag not spin stabilised.
pelet: faster straighter balistic on smaller distance, slug: slower but more total kinetic energy due to being slower it get more time to store kinetic in the barel; so more drop but much more predictable drop... and usable distance increased and hit energy at long range increase.. 20+ joule go for heavy pelet or slug (slug more heavy best suited for powerfull airgun... cheap diana old 7.5j : go cheap ligh ... expansive new powerfull airgun? do u really want ur piston hard hit end travel while shoting cheap light pelet? ... )
I have to say thanks to you for the comment you did because I didn't think about the pellets vs slugs in that format and had partially forgotten about those aspects so again thanks for the reminder
Seriously dude, you should take this video down because you are factually incorrect and making yourself look like a fool. You are shooting a lighter pellet at the same pressure as the heavier slug, which results in higher velocity with the lighter pellet which is why it is hitting higher. To prove your point about BC, you would have to shoot the slug at the same velocity as the pellet. The pressure in the reg is not relevant. The only thing that would prove your point using drop on target is for any side by side projectile evaluation to be fired at the same velocity. You might want to watch this video TWICE to enhance your basic understanding: ua-cam.com/video/lAxL38nBeFY/v-deo.html
Well stated. I understand he thinks he is giving great tips on airgun shooting. He just needs to slow down and think it through. I thought I was losing my mind watching this.😉
You have to shoot both pellets and slugs at the SAME velocity then the slugs 2x higher BC will produce (Less drop) The low BC pellet is never going to catch up to the 2x higher BC slug even if the BC goes up for the pellet. You were probably shooting 800 fps slug vs 900 fps pellet. I do agree that the JSB 15.9s are great shooting and save on air and money. I shoot them too. If you want more power use rimfire.
Two words for you. Barrel friction. Slugs have a lot more of it than pellets. But any projectile with the higher ballistic coefficient is going to be faster and travel farther and retain more energy, everything else being equal. Physics don't cease to exist because you think your pellet hits harder.
21 grains vs 15.89 grains out of the same gun on the same settings is not a fair test. However if they were both moving at the same speed the slug would carry far more fpe down range while also retaining more speed. A chronograph measuring only muzzle velocity is only telling part of the story. Having chronograph readings at the muzzle and down range showing the fps as well as the fpe would take all the guess work out of this ! As far as hunting goes, all slugs aren't created equal. With the H&N slugs I was getting the "ice pick" effect. Small hole in, small hole out. Switched to a custom 22 grain slug(22 cal) with softer lead and it leaves a big hole going in and a bigger hole going out. JSB Hades, H&N Barracuda Hunter and Hunter extreme are the most devastating pellets I've used. This is from real world testing being that I knock off 40 to 60 iguanas every weekend .
Pellets are stabilized in flight very differently from slugs. While they are both, in rifled barrels, stabilized by spin provided by rifling, pellets have an additional type of stabilization provided by their skirted shape. Pellets work like badminton shuttle cocks or “birds”. They can self stabilize even in smooth bores within certain velocity limits. Slugs depend on the right rifling twist rate for the length, diameter, weight and velocity of the projectile. Pellets seem to perform better than they should on small game compared to slugs that are delivering much more kinetic energy.
That's right bro. And as you know, the skirt on the pellet causes the pellet to lose it's muzzle velocity in less time than a slug of the same weight and muzzle velocity, because the slug doesn't have a skirt. And a skirt causes air resistance.
Lmfao 😂 wtf got to send this to people.. The Ballistic Coefficient of slugs is far superior to anything that can be achieved with diabolo pellets. That means more energy further downrange, combined with less susceptibility to wind.
Not. A felon might be able to own an air rifle in States that don't define an air rifle as a firearm. If a felon is caught with a firearm they are going back to jail, unless they have had their rights restored by a court,
The factors at play are the weight of the projectile, the Ballistic Coefficient of the projectile (that is fixed), the range, and velocity. The BC is how aerodynamic the projectile is, ie how well it retains its muzzle velocity. Given the same gun settings, a heavier projectile will have a slower muzzle velocity than a lighter one. To keep things simple, remove the weight difference by making the pellet the same weight as the slug. Slugs have higher BC than pellets, therefore will retain their velocity better than a pellet. A pellet slows down faster than a slug due to lower BC. Keeping your zero on scope the same, and centering cross hairs on bulls eye, if your impact of your slug is bulls eye, then the impact of your pellet will be lower than the slug at extended ranges. A slug is capable of 300 meter range where a pellet is not because the velocity will bleed off much faster with pellet. (A much more pronounced arc). The slug shoots flatter and farther because of the superior BC. Remember, equal weight, the muzzle velocities are the same, but the pellet will always slow down faster, striking lower than an equal weight slug. If you lower the weight of the pellet enough, it will have a higher muzzle velocity, making up for the lower BC, and maybe hitting the same spot as a slug, but longer range and better aerodynamics would soon give the advantage to the slug again because it carries its velocity farther down range.
Great content and shooting as usual. I would like to add my 2 cents worth. At one time in life I participated in thousand yard bench rest (NBRSA) . In our game what determined drop was time of flight. This was simply gravity. The time of flight was determined by muzzle velocity, BC of the projectile, and of course air density. I would think this would also apply to airguns. Thanks for the great video.
@@ALLABOUTAIRGUNS its just clear you don't understand how BC works, BC is just air resistance and does not increase on a fired projectile like you think it does
Thank you for your commonsense solution to the cost. I also feel the same. I stick with only crosman pellets. Anything beyond that I use a 22lr .Great video.
Technically you don't have the same gun settings. ONLY the psi was the same. In your test the pellet trap more air with the flared skirt and the slug is not efficient in the same barrel. Same weight and speed exiting the barrel the slug is higher at 100 yards. And much less wind drift. A rifle with a choked barrel shooting pellets at 900fps and a rifle with a non choked barrel shooting slugs at at the same weight at 900fps show a slug will outperform the pellet all day. Also expanding hollowpoint slugs do way more damage than pellets. I hunt and do pest control year round. But I do love ❤️ Predator Polymags Just my humble opinion 😌 My 2cents Just saying.
Same gun settings as in hammerspring and reg pressure nothing changed on the gun except projectile weight/type...which changed the muzzle velocity...this barrel is a tight full bore 5.35mm ...same weight pellet and slug at 800fps the pellet dropped 1" at 100yd compared...depending on the slug/pellet type ...either one can do more damage on impact with alot of variables to consider .....slugs have more penetration due to weight distribution in the rear and pellet weight is more in the head...slugs have more wind drift due to being actually stabilized by the right hand twist of this barrel at certain rpms and ranges...pellets tend to be more accurate than slugs due to this reason
at same projectile weight 21gr pellet vs slug at the same velocity, pellet was 1" lower impact on this same target/distance...but as I pointed out just switching the ammo type I had a higher impact with pellets
Thanks for the update. I really didn't think the pellet would have been an inch lower when shooting the same weight and velocity. And for the record I prefer shooting pellets as well due primarily to cost.
If same weight slugs hit higher than pellets it proves bc is better. Stabilization does not mean better bc because by the time it stabalizes iit already lost some speed trying to stabilize
@@josemoreno5758 didn't say it wasn't but that is only at the same velocities....I said changing the ammo at same gun settings...pellets have less bearing surface than slugs and I also stated pellets increase BC in flight and slugs decrease BC in flight due to being the highest BC at muzzle...and pellets tend to be more accurate and precise then slugs which I can shoot both because I know what I am looking for...not using velocity as a reference
177cal slugs aren't as expensive. However I also like pellets. $11.49 per tin of 500 for Crossman ultra mags 10.5gr. domed. I have been lucky that my BSAR10 SE and Avenger love the Crossman pellets. But my Gauntlet only likes JSB. It's confusing me about your saying slugs loose BC compared to pellets. I was told the opposite. That's another reason I shoot pellets. I thought they lost energy quickly. That seemed better for a urban environment. Iam not sure if you are correct. Everyone else says different. There are numerous videos showing better energy retention for slugs. Nevertheless, I appreciate your time. Perhaps Iam missing something. God bless you brother. 🎯👍 PS: Just read the link article. It makes sense now.
@@hutch0025 At Pyramid Air they are the same price. Main difference is that the 14gr 22cal are considered light weight for a 22. Whereas the 10.5gr are heavy for a 177cal. A better comparison is the Crossman 19gr., which is considered heavy for 22cal. They are way more expensive. The 7.4gr 177cal wadcutter is $19 bucks for 1250 rounds. That is a lightweight 177cal. But I agree it's strange, because the 14gr still have more material than the 10.5gr. Either way, if your gun likes them? They are hard to beat.
I need help understanding this when you say we're on what do you mean? cuz shouldn't you be hitting closer to the sticker if you are sighting in at those distances or is it just that you get on paper at those distances?
I agree with some of this but, hollow point slugz will do more damage than pellets at longer ranges is why professionals use them. If you want to shoot them, actually you can do it cheaper than pellets by making your own for about 2 cents a shot! Of course you would have to buy the molds first. I shoot pellets only because for me, it is easier for me and suits my needs for my style of pesting and shooting. I do use slugs in my larger big bores no brainer. See what I mean? Ed da pro snippin backyard man💥👇💪😱
Just had a chance to see this. I have my Akela .22 sighted at 25yds. and shoot dead nuts out to 40 with NSA 31.2g .2160 slugs. I figured the smallest diameter with a long bullet would keep the velocity up. At 25 yds it goes thru a 5/8 sheet of plywood. No velocity meter, sorry. I've shot11 different pellets and have to say that both my Marauder and Akela seem to love them all other than light pellet don't have the penetration like the slugs. Longest squirrel was approx. 50 yd head shot, aimed just above the ear and put it in. Great videos.
I have a very very budget configuration. P35 rifle, and Hatsan "Destroyer" 28 gr slugs. I impact shot after shot on an 8"/20 cms target at 186 yds/170 mts. I´m 150 ft/45 mt over the target.
Was the pellet and the slug the same weight because of course if one is heavier it's going to drop lower plus the FPS is going to be different and you need to do video with the same weight slug and pellet or do a video with a heavier palet and lighter slug to do a more accurate comparison try to get the same weight on each
@@ALLABOUTAIRGUNS Whatever, just shoot over a chronograph at different ranges and check your numbers, speed and energy simple. Your mixing up BC and drop from gravity, faster time to target means less drop.
Perhaps the gun youre using wasnt meant to shoot slugs…. Aea guns prefer pellets…. If you dont find a slug that fits snug to the barrel youre rounds will drop due to the inefficiency
Hello James, I have a question, I see the wind is blowing pretty good that day. My question is, why the wind seems to have no effect on the cardboard box and the balloon, but the soybean leaves are blowing like crazy? Would like to see your results of a test 21gr. pellet vs 21gr. slug. on the same tune you have at the time of this video.
Have u ever tested the mcx virtus air rifle in 22? I’ve own a few of these same virtus Airgun and they all shoot the same which is not very accurate.It’s only a 12 fpe gun but with a few mods u can get it up to 16-17 fpe. It has an accuracy problem and all 3 virtus that I had shot all had a messy grouping. You should make a video on how to fix and correct the accuracy on this gun. Personally I think the barrel needs a crown done.
if pellet and slug are same weight and shot at same velocity the slug will have a higher impact its physics a slug is more aerodynamic and will slide through the atmosphere easier than a diablo shaped pellet therefore the slug will retain more energy at the longer distances than the pellet if you are hunting 60yds or less use a quality pellet at 900 to 950 fps if you are hunting further out use a slug at the same 950 its simple physics at long range slugs will out perform a pellet because pellets are designed to loose velocity quickly for a safety factor
10:15 The ballistic coefficient of a projectile has everything to do with retaining energy, literally everything. You also say that the BC changes as soon as the projectile leaves the barrel. That's utter noncense . . . every slug and pellet has it's own set ballistic coefficient, no matter at what speed you shoot them, the ballistic coefficient of that projectile never changes, it doesn't decrease nor will it increase. It is a SET number, otherwise they couldn't print the BC on the box. The only projectile that I know of that could changed it's BC during flight was the French Concorde when it lifted the cockpit.
Advertised BC is predetermined. It isn't specific to your rifle, your fps settings etc as you imply. To achieve the "Advertised" BC you have to fire the bullet at a specific FPS from a specific barrel length and ROT.
James I totally agree with you my friend if I want to shoot real far yardage I would shoot a powder gun. I get great results with pellets so why go to slugs when there more money and you get less.
Bc at 800 is better or worse at 1000? More resistance. Cast bullets all seem to vary by speed. Yaw makes them freeky. I used to watch some spiral and drop more. Then others flew strait and dropped less. You think alot. Keep it up bro!
My personal take on this is thats its very much up to what applic🎉ation the ammo is needed for. Hard to say wich is generally better.just my opinion.👍🇸🇪🔫
You do not understand BC. The BC is fixed for a projectile. The only way the BC can change is if the weight changes or shape changes. After the projectile leaves the barrel, the weight and shape is fixed.
You seem to conflate accuracy with amount of drop.... Muzzle velocity is key to controlling drop, while tuning the settings for the ammo is key to accuracy.
Maybe because I'm newer to taking air rifle shooting as a jobby and not just something I had in the closet and I know this video is a year old but I'm kind of not understanding what is shown here. Two different weight projectiles fired at two different velocities hit at two different spots.. wasn't that to be expected right from the get-go before firing the first time? I'm not understanding the truth that was revealed.
Pellets increase BC downrange (800 to 600fps are the best velocity) and Slugs decrease BC as they go downrange (at muzzle is the highest BC the slug will ever have)
pelet: faster straighter balistic on smaller distance, slug: slower but more total kinetic energy due to being slower it get more time to store kinetic in the barel; so more drop but much more predictable drop... and usable distance increased and hit energy at long range increase.. 20+ joule go for heavy pelet or slug (slug more heavy best suited for powerfull airgun... cheap diana old 7.5j : go cheap ligh ... expansive new powerfull airgun? do u really want ur piston hard hit end travel while shoting cheap light pelet? ... )
It's all "slugs" or "bullets" for me, since they are far cheaper than pellets. I just buy Lee bullet mold (around $30 on ebay) and cast all my 357/9mm bullets. All I need is lead to make my slugs/bullets. And they work great for my .357 air guns. If you can recover the lead after shooting, then you can recycle them and make new ones from used bullets, so net cost of my 357 slug/bullets is almost nothing, making my 357 air gun even cheaper to shoot than .22 pellets or even .177 pellets.
Anytime I'm buying pellets or slugs I buy from pyramid Air and I'm buying at least 16 tins and spending at least $150 that way I take advantage of free 1 day shipping to NY and I get 4 tins for free
Hey man not to wreck your video but you are wrong about many things. Understanding ballistics and saying you know what your are talking about and using this video as proof doesn’t make you right. In order to compare the ballistics of a pellet vs slug you need to shoot them at similar velocity. This is like comparing a 556 to a 45-70 cartridge. Of course the 556 will shoot higher faster because it shoots faster right out the barrel. Pellets skirts slow down the projectile compared to slugs. You don’t believe me then shoot the slug at the same speed as the pellet and put a chrono down range. You’ll change your mind. Slugs are for hunting and they are better than pellets. This is coming from someone who shoots mostly pellets. I’ve shot slugs out of my fx and the faster you get them the better they perform.
I've shot them at similar velocities and my shooting speaks for itself...cards, aspirins off balloons sub moa groups @100yd, I've done it all man....pretty sure I'd know as I shoot both pellets and slugs very very accurately and since this video I can leave the gun on same settings and now I am up to 6 different slugs all sub moa bub so
That has nothing to do with how ballistics work. Shooting accurately with them and knowing that slugs shot at the same speed as pellets will result in better long distance performance is 2 different things. Just because a pellet you shoot “outperforms” a slug that you’ve tested doesn’t make what you said true. Some guns aren’t really made to produce great results with slugs because the speeds needed to be effective are much higher than they can achieve. The fact of the matter is that slugs will outperform any pellet in drop and wind drift. Comparing a 900 fps pellet vs a 780 fps slugs is like comparing a 9mm vs 380 in speed. Plug your info for your pellet into any ballistic software and then for the slug you were using and then use the same fps for both and I’d place money that the slug will outperform the pellet in every condition. You can’t deny physics and what you are saying is just not possible. Sure you might can get better groups with a pellet sometimes but holding the same point of aim for each shot slugs running the same fps will drift less than pellets.
Don't bullet manufacturers take into consideration the twist rate of the rifling in the kind of rifles they're developing a round for as well as the length of the barrel and a bunch of other parameters like how long the slug has to be to be stable in flight? I feel like pellet manufacturers have just squashed some lead into the shape of a bullet and put it out there for people to buy, Air rifle pellets are both drag and spin stabilised and have been working well for like a century now,, many people can't access rifles capable of pushing these things fast enough for it to make sense,, we all wish that we could though
I've done some unscientific testing into 3/4" yellow pine boards at 25 yards and I've came to the conclusion BC numbers are more BS than anything, at least in regards to air rifle pellets. My test rifle was/is a .22 Diana 350 Magnum, the pellets I used in my tests included the Crosman 14.3gr HP, H&N 14.66gr FTT with a claimed BC of .019, Barracuda Match 21.14gr with a claimed BC of .039,Norma 15.9gr, Norma 17.6 gr with a claimed BC of .023, Baracuda Hunter Extreme with a claimed BC of .027 and last but not least the Daisy Hollow Points. Of all these, which one do you think fully penetrated the board? The Daisy Hollow Points did. Unless Daisy is making their pellets using some secret outer space material, these results seem counter intuitive, just sayin.
@@ALLABOUTAIRGUNS Wow!!! Thats a pretty 💩 b.c. Lol! It's still accurate though. Both of my AEA CHALLENGER SL's are accurate with the new AEA reg. I'm telling anyone thats looking for a high powered sub 300$ gun. Go with the Challenger long stock. Not the Bullpup. 😂
I read the link The heavier it is the better bc Which in theory is correct Now a lab radar at 100 on clay or ballistics gell will prove your argument with both Speed and energy on target Which equals bc
I shoot .25cal mostly no 500count pellets for them. 200count is the most I've found, and most are 150count. I think I paid less for my 135ct 34.9gr nsa slugs than I did my 150ct h&n hornets by a good bit.
It's a bit off subject James, but even if you used to "be" a felon - having committed a felony, after you repented to the Judge of All, you would no more at all be a felon. And neither are all who have repented of it.
'pellet had a higher impact even though it had a higher muzzle velocity' - yes, it would. If you propel a lighter projectile with the same force as a heavier projectile, the lighter will travel faster and, if within range, reach your target with less evident drop as it got there quicker. You're comparing 800 fps slugs to 950 fps pellets... Why? What grain weights? What FPE at point of impact?
I think you need to see if the slug is spiraling. If it is then it isn’t efficient in flight . Also , what is the diameter of the Diabolo pellet vs. the slug . Your barrel may favor the Diabolo over the slug . I’m happy for you if you like the Diabolo pellets but for me the slug is the way to go .
It's not spiraling...flies true on target, I can see my projectiles in flight at this velocity and setting, I find out the trajectory of each projectile and have my own tuning methods other than velocity to correct the impact/groups ...I hit/split cards at low velocities at 100yd all the time with pellets
@@ALLABOUTAIRGUNS the slug design is still evolving where the the Diabolo design pellet has reached its Plateau . You may change your mind with newer designs come out . It is critical to have the right diameter due to the amount of contact area of the slug on the rifling as compared to Diabolo pellets .
@@hotchihuahua1546 @14:01...if you understand the projectiles flight path like I do, I can shoot anything like in the examples of this video, I hit/split playing cards at 100yd back to back all the time with pellets @800fps and sub moa group...again you have to know what you're doing
@@STKO2011 the Airgun world is changing and the slug has paved the way . The Diabolo pellet will always have its limits . I have been shooting pellets for 50 years and I can tell you at distance the best pellet can’t compete with the best slug at long distance .
I watch the videos but this is not a very good test. Projectiles are not flying at the same speed to begin with and you are not recording lost energy or anything down range. Also even if a pellet increases BC it starts far far lower and wont ever reach the slug BC so I think that’s not much or a win for a pellet either. Pellets are excellent at close to mid range, slugs are the future and long range performers
Have you seen what I can do with pellets? Either way pellets or slugs you really have to know what you are doing if you want the most out of them...I am a precision shooter, I don't shoot at random sized targets...I shoot at playing cards on edge all the way out to 200yd consistently...and pencils with pellets freehand standing out 200yd...besides that price per quantity and pellets are known to be more accurate even though I am able to shoot slugs that good
First, I don't trust the opinion of anyone who puts their head in the center of the screen on a video like a first-week newb. Second, you can come up with all of the reasons you can imagine for an airgun being superior to a firearm, but you can't explain to me why they aren't used by any military or police force. They are a NOVELTY, a fallback for when there is no ammo available and you haven't learned to reload. I own three air rifles, a .22, .25 and a .30 cal, but I totally HATE them.
You’ve seen this already commented but I’ll say it again. You have to compare same grain weight 15.89 with no power change will obviously hit higher than a 21 grain, you should know this. In addition, the barrel of the rifle makes contact with 70% or more of the slugs whereas it only makes contact with 20% of the pellet which means more drag from the slug. Measure same grain dude slug will be a bit slower cuz of drag but this is terrible what you did. Usually like you content but this one is ridiculous
Awesome vid man and again I've said before but we're I'm guessing an hour or less away we need to meet up ill bring my 357 terminator hpss plus and many other guns
I wish my gun shot 800fps fuck. It came in shootingjust under 500 butni had to tune it to get it up to 600 and thats the absolute most i can get for .25cal in my country
At first I was way skeptical because of all the hype around slugs. But, you convinced me. I was sold on the price discrepancy alone. And fuckin' fantastic shooting my friend. Subscribed!
Wrong again dude...slugs have more drag in the barrel and your comparison is with a much heavier slug. I've shot thousands of varmints out past 150yds with an airgun and I can tell you 100% for sure that pellets are less accurate and have less energy at that range. The BC of a projectile does not ever change.
The only way to truly do this test is if both projectiles are shot at the same speed. With close to a 150fps difference there is no way to compare the two. This is a total waste of time to watch!
I did shoot both at same velocity as a side note and pellets were 1" lower impact at same weight on this same target/distance...point is to fully understand trajectory and I do
Your graphic is confusing because when ballistic coefficient increases or is "high", and become more efficient, the number gets bigger and the drag is less, so the projectile coasts to the target more efficiently. When the ballistic coefficient decreases the number gets smaller, the efficiency is less and drag is increased. So a pellet has a decreased ballistic coefficient and a slug has an increased ballistic coefficient. But the drag of the projectile is greater on the pellet meaning it looses energy sooner as it travels to the target. Projectiles have many BC's depending on velocity and uniformity of the projectile. This is why Sierra lists 3 or 4 BC's depending on velocity.
The bc of the slugs isn't enough to over come the faster speeds of the pellets at one hundred yards. Try going out to 150 or 200 yards. The other advantage of slugs is less wind drift, though once again air gun slug bc 's aren't in the same ball park as center fire rifle modern projectiles. Time to target vs gravity = verticle drop. One of the constants in shooting.
@ 9:58 that's what I said...you're right can't compare centerfire to airgun ammo but 22LR isnt centerfire it's rimfire which is more of a slug/pellet combo due to the way it swages to the bore and is shot in the pellet/slug velocity, if you the read article I pinned it clearly states pellets are more accurate than slugs (spin drift/stabilization due to BC decreasing in flight)
He is comparing a 15gr pellet to a 21gr slug lol if used a 15gr slug it would kick the pellets butt… now accuracy pellet are more accurate but if you find the right slug just like you have to find the right pellet slug all day long
@@bushwhookie1334 If you slow down the same weight pellet it’s going to hit lower at the same distance. If you speed up the same pellet it should hit higher. Shoot the pellet and slug at the same speed and see what happens as long as the gun shoots slugs good.My Umerex Origin .22 I tried several different slugs in it and it did not like any of them.
@@fathertimencUSA I have a hatsan .25 flash. Shooting 34gr slug and 33.95gr mk2 pellets the slug is higher because of the BC.. now if your gun don’t shoot slugs good then there is two things the rifling is not good for slugs or your slugs are to lose say .217 air is going over it need a .218 .219 if that don’t work stick to pellets
@@bushwhookie1334 Yes they are the same weight basically. The slug might be going a little slower because of the more surface area against the barrel but probably not as much the weight difference he is using where the pellet is going a significant fps faster than the slug. Even with the better BC of the slug if it is going a significant amount slower and has more weight of course it will group lower than the lighter faster pellet. But range would also play a part since pellets slow down faster than slugs because of their BC.
When a keyboard warrior thinks the understands something. Higher muzzle velocity means projectiles go farther faster. Higher bc means projectiles retain velocity longer and therefore travel farther. You didnt have good groups. Your groups were dogshit. The faster a projectile goes and the heavier it is the more energy it has so higher a higher bc means more energy is retained at a distance which means the bc is directly related to energy retainment.
I'm sorry this guy is clueless he shouldn't be advising anybody about her what to shoot. Pellets and slugs are two different creatures. If shot at the same speed a pellet will bleed off its speed so much faster just because of the BC compared to a slug which has a better BC if shot at the same speed the slug will retain speed and energy @ a longer distance. He can't even explain why the slug is shooting slower than the Let me explain why the slug came out, #1 the slug is heavier than, #2 because the slug has a longer surface that rides the barrel rifling, this creates friction does reducing the speed of the slug. But if you were able to tune the slug to shoot the same speed as the pallet the slug will always out shoot the pellet
Yeah if I'm getting pellets to shoot good as slugs all the way up to 200 yards without the extra cost and makes perfect logical sense... especially since pellets are known to be more accurate and my shooting proves that but I also can shoot slugs very good
Ballistic Coefficient (BC) is a figure of merit for the shape of a projectile. Since the projectile's shape does not change during flight, therefore the BC of the projectile also remains constant, regardless of whether the projectile is down range or right next to the muzzle..... or even if it is inside the box it came in when you bought it. en.wikipedia.org/wiki/Ballistic_coefficient The difference between the 2 projectiles' drop is due to the time of flight (as many have already pointed out in the comments). Go faster and the drop is less, go slower and you get more drop.
BC changes consistently because the projectile velocity at range changes consistently and therefore the BC changes as well: A drag coefficient can also be calculated mathematically: Cd = 8/ρv^2πd^2 where: Cd, drag coefficient. ρ density of the projectile. v, projectile velocity at range. π (pi) = 3.14159… d, measured cross section (diameter) of projectile It's right in the Wiki definition you posted.
Here's a good article to read as reference to the topics in this video thanks for watching!!!
www.airgundepot.com/vault/articles/all-about-ballistic-coefficient/
Your science is off. In order to have a valid expirament to find BC the weight and velocity at the muzzle must match.
BC tells the difference between same weight projectiles slowing down during flight.
All bullets fall at the same speed 9.8Ms_2.
BC and drop are not directly related.
Drop is a result of gravity acting on the projectile. So if you shoot a projectile with a lower speed, it will drop more during its flight than a faster projectile, simply because gravity has more time to act upon it.
High BC projectiles retain more speed so they cover the distance faster, compared to projectile with the same muzzle velocity. (thus minimizing the effect of gravity.)
Correct drop is purely a product of velocity and time in the air the gravity is consistent.
I would word the high BC as they retain their speed better so if they start slower they overtake at some point down range, so long range they will cover the distance faster but close range it's whatever is fastest.

Can I ask a newbie type question with regards to pellets and slugs. If you zero at 100 yds for both does that mean that each will be zero from 0 to 100 yds?
@@jackbisson9226 maybe, if you pellet and slug have the same BC, yes.
But generally we shoot slug because they have a higher BC, so your slugs will drop less than your pellets.
So if you zero slugs at a 100, your pellets will be zero'ed at maybe 80ish yards
Every bullet drops at exactly the same time, one lands higher on the target because it gets there faster and has had less time to fall.
The slug is heavier so with the same setting you are shooting it slower. As a result, it will drop more over the same distance because its travelling for a longer period of time. The higher BC of the slug means it will lose less of its total velocity over a given distance compared to a pellet which is predominately drag not spin stabilised.
pelet: faster straighter balistic on smaller distance, slug: slower but more total kinetic energy due to being slower it get more time to store kinetic in the barel; so more drop but much more predictable drop... and usable distance increased and hit energy at long range increase.. 20+ joule go for heavy pelet or slug (slug more heavy best suited for powerfull airgun... cheap diana old 7.5j : go cheap ligh ... expansive new powerfull airgun? do u really want ur piston hard hit end travel while shoting cheap light pelet? ... )
I have to say thanks to you for the comment you did because I didn't think about the pellets vs slugs in that format and had partially forgotten about those aspects so again thanks for the reminder
Lol I love this guy, he never knows anything about actual ballistics. Great content
Seriously dude, you should take this video down because you are factually incorrect and making yourself look like a fool. You are shooting a lighter pellet at the same pressure as the heavier slug, which results in higher velocity with the lighter pellet which is why it is hitting higher. To prove your point about BC, you would have to shoot the slug at the same velocity as the pellet. The pressure in the reg is not relevant. The only thing that would prove your point using drop on target is for any side by side projectile evaluation to be fired at the same velocity. You might want to watch this video TWICE to enhance your basic understanding: ua-cam.com/video/lAxL38nBeFY/v-deo.html
Well stated. I understand he thinks he is giving great tips on airgun shooting. He just needs to slow down and think it through. I thought I was losing my mind watching this.😉
And 15.89 vs 21 lol 950fps vs 800… if the pellet was 21gr vs 21gr slug @800 fps different story 21gr pellet be in the dirt at 100
You have to shoot both pellets and slugs at the SAME velocity then the slugs 2x higher BC will produce (Less drop)
The low BC pellet is never going to catch up to the 2x higher BC slug even if the BC goes up for the pellet.
You were probably shooting 800 fps slug vs 900 fps pellet.
I do agree that the JSB 15.9s are great shooting and save on air and money. I shoot them too. If you want more power use rimfire.
Two words for you. Barrel friction. Slugs have a lot more of it than pellets. But any projectile with the higher ballistic coefficient is going to be faster and travel farther and retain more energy, everything else being equal.
Physics don't cease to exist because you think your pellet hits harder.
21 grains vs 15.89 grains out of the same gun on the same settings is not a fair test. However if they were both moving at the same speed the slug would carry far more fpe down range while also retaining more speed. A chronograph measuring only muzzle velocity is only telling part of the story. Having chronograph readings at the muzzle and down range showing the fps as well as the fpe would take all the guess work out of this ! As far as hunting goes, all slugs aren't created equal. With the H&N slugs I was getting the "ice pick" effect. Small hole in, small hole out. Switched to a custom 22 grain slug(22 cal) with softer lead and it leaves a big hole going in and a bigger hole going out. JSB Hades, H&N Barracuda Hunter and Hunter extreme are the most devastating pellets I've used. This is from real world testing being that I knock off 40 to 60 iguanas every weekend .
Pellets are stabilized in flight very differently from slugs.
While they are both, in rifled barrels, stabilized by spin provided by rifling, pellets have an additional type of stabilization provided by their skirted shape. Pellets work like badminton shuttle cocks or “birds”. They can self stabilize even in smooth bores within certain velocity limits. Slugs depend on the right rifling twist rate for the length, diameter, weight and velocity of the projectile.
Pellets seem to perform better than they should on small game compared to slugs that are delivering much more kinetic energy.
Thanks!
That's right bro. And as you know, the skirt on the pellet causes the pellet to lose it's muzzle velocity in less time than a slug of the same weight and muzzle velocity, because the slug doesn't have a skirt. And a skirt causes air resistance.
@@senatorjosephmccarthy2720 Ever seen the Lyman Diablo?
Skirt is a flaw. You cant shoot pellets at very High velocity. Just look at bullets.
@@bratarnolda1014 good thing air guns are total crap and cant shoot anyways
Lmfao 😂 wtf got to send this to people.. The Ballistic Coefficient of slugs is far superior to anything that can be achieved with diabolo pellets. That means more energy further downrange, combined with less susceptibility to wind.
Yes that’s true but at shorter ranges it’s hard finding a slug as accurate as the jsb pellets

@@hacunamatata6802 state laws cannot supersede federal law that's not how it works
The factors at play are the weight of the projectile, the Ballistic Coefficient of the projectile (that is fixed), the range, and velocity.
The BC is how aerodynamic the projectile is, ie how well it retains its muzzle velocity.
Given the same gun settings, a heavier projectile will have a slower muzzle velocity than a lighter one.
To keep things simple, remove the weight difference by making the pellet the same weight as the slug.
Slugs have higher BC than pellets, therefore will retain their velocity better than a pellet.
A pellet slows down faster than a slug due to lower BC.
Keeping your zero on scope the same, and centering cross hairs on bulls eye, if your impact of your slug is bulls eye, then the impact of your pellet will be lower than the slug at extended ranges. A slug is capable of 300 meter range where a pellet is not because the velocity will bleed off much faster with pellet. (A much more pronounced arc). The slug shoots flatter and farther because of the superior BC.
Remember, equal weight, the muzzle velocities are the same, but the pellet will always slow down faster, striking lower than an equal weight slug.
If you lower the weight of the pellet enough, it will have a higher muzzle velocity, making up for the lower BC, and maybe hitting the same spot as a slug, but longer range and better aerodynamics would soon give the advantage to the slug again because it carries its velocity farther down range.
Great content and shooting as usual. I would like to add my 2 cents worth. At one time in life I participated in thousand yard bench rest (NBRSA) . In our game what determined drop was time of flight. This was simply gravity. The time of flight was determined by muzzle velocity, BC of the projectile, and of course air density. I would think this would also apply to airguns. Thanks for the great video.
Yep it definitely applies...slugs are more like bullets and pellets are little different but variables still apply
@@ALLABOUTAIRGUNS its just clear you don't understand how BC works, BC is just air resistance and does not increase on a fired projectile like you think it does
Thank you for your commonsense solution to the cost. I also feel the same. I stick with only crosman pellets. Anything beyond that I use a 22lr .Great video.
Technically you don't have the same gun settings. ONLY the psi was the same. In your test the pellet trap more air with the flared skirt and the slug is not efficient in the same barrel. Same weight and speed exiting the barrel the slug is higher at 100 yards. And much less wind drift.
A rifle with a choked barrel shooting pellets at 900fps and a rifle with a non choked barrel shooting slugs at at the same weight at 900fps show a slug will outperform the pellet all day.
Also expanding hollowpoint slugs do way more damage than pellets. I hunt and do pest control year round.
But I do love ❤️ Predator Polymags
Just my humble opinion 😌
My 2cents Just saying.
Same gun settings as in hammerspring and reg pressure nothing changed on the gun except projectile weight/type...which changed the muzzle velocity...this barrel is a tight full bore 5.35mm ...same weight pellet and slug at 800fps the pellet dropped 1" at 100yd compared...depending on the slug/pellet type ...either one can do more damage on impact with alot of variables to consider .....slugs have more penetration due to weight distribution in the rear and pellet weight is more in the head...slugs have more wind drift due to being actually stabilized by the right hand twist of this barrel at certain rpms and ranges...pellets tend to be more accurate than slugs due to this reason
@@ALLABOUTAIRGUNS I get it.
You're a pellet fan.
That's OK 👍
Just makes sense for me when I can shoot either one accurately but it only comes down to price 👍
I would be interested in seeing what the results would be for this test if the pellets and slugs were the same wait.
at same projectile weight 21gr pellet vs slug at the same velocity, pellet was 1" lower impact on this same target/distance...but as I pointed out just switching the ammo type I had a higher impact with pellets
Thanks for the update. I really didn't think the pellet would have been an inch lower when shooting the same weight and velocity. And for the record I prefer shooting pellets as well due primarily to cost.
@@kelsonrogers7250 yep! No problem
If same weight slugs hit higher than pellets it proves bc is better. Stabilization does not mean better bc because by the time it stabalizes iit already lost some speed trying to stabilize
@@josemoreno5758 didn't say it wasn't but that is only at the same velocities....I said changing the ammo at same gun settings...pellets have less bearing surface than slugs and I also stated pellets increase BC in flight and slugs decrease BC in flight due to being the highest BC at muzzle...and pellets tend to be more accurate and precise then slugs which I can shoot both because I know what I am looking for...not using velocity as a reference
I have been extremely satisfied with slugs. What is your opinion on close range knockdown power. Close range the FX hybrid 30 Cal are devastating
The Hybrids in .30 are a killer even at 75+ yards. I shoot them almost exclusively: ua-cam.com/video/X7hhD70_0SU/v-deo.html
177cal slugs aren't as expensive.
However I also like pellets. $11.49 per tin of 500 for Crossman ultra mags 10.5gr. domed.
I have been lucky that my BSAR10 SE and Avenger love the Crossman pellets. But my Gauntlet only likes JSB.
It's confusing me about your saying slugs loose BC compared to pellets. I was told the opposite. That's another reason I shoot pellets. I thought they lost energy quickly. That seemed better for a urban environment. Iam not sure if you are correct. Everyone else says different.
There are numerous videos showing better energy retention for slugs.
Nevertheless, I appreciate your time. Perhaps Iam missing something.
God bless you brother. 🎯👍
PS: Just read the link article. It makes sense now.
that’s weird the same pellets in .22 are cheaper, for the same 500 count …
@@hutch0025 At Pyramid Air they are the same price. Main difference is that the 14gr 22cal are considered light weight for a 22. Whereas the 10.5gr are heavy for a 177cal. A better comparison is the Crossman 19gr., which is considered heavy for 22cal. They are way more expensive.
The 7.4gr 177cal wadcutter is $19 bucks for 1250 rounds. That is a lightweight 177cal.
But I agree it's strange, because the 14gr still have more material than the 10.5gr.

I need help understanding this when you say we're on what do you mean? cuz shouldn't you be hitting closer to the sticker if you are sighting in at those distances or is it just that you get on paper at those distances?
zeroed horizontally at 50yd and shot 100yd to see vertical drop of pellet and slug at same gun settings
I agree with some of this but, hollow point slugz will do more damage than pellets at longer ranges is why professionals use them. If you want to shoot them, actually you can do it cheaper than pellets by making your own for about 2 cents a shot! Of course you would have to buy the molds first. I shoot pellets only because for me, it is easier for me and suits my needs for my style of pesting and shooting. I do use slugs in my larger big bores no brainer. See what I mean?

Just had a chance to see this. I have my Akela .22 sighted at 25yds. and shoot dead nuts out to 40 with NSA 31.2g .2160 slugs. I figured the smallest diameter with a long bullet would keep the velocity up. At 25 yds it goes thru a 5/8 sheet of plywood. No velocity meter, sorry. I've shot11 different pellets and have to say that both my Marauder and Akela seem to love them all other than light pellet don't have the penetration like the slugs. Longest squirrel was approx. 50 yd head shot, aimed just above the ear and put it in. Great videos.

Was the pellet and the slug the same weight because of course if one is heavier it's going to drop lower plus the FPS is going to be different and you need to do video with the same weight slug and pellet or do a video with a heavier palet and lighter slug to do a more accurate comparison try to get the same weight on each

Hello James, I have a question, I see the wind is blowing pretty good that day. My question is, why the wind seems to have no effect on the cardboard box and the balloon, but the soybean leaves are blowing like crazy? Would like to see your results of a test 21gr. pellet vs 21gr. slug. on the same tune you have at the time of this video.
Box was staked in the ground, balloon was taped to the box, I uploaded a video this past year 21gr pellets vs slugs
Out of curiosity, what power was the scope set to at that 100 yd shot?
Have u ever tested the mcx virtus air rifle in 22? I’ve own a few of these same virtus Airgun and they all shoot the same which is not very accurate.It’s only a 12 fpe gun but with a few mods u can get it up to 16-17 fpe. It has an accuracy problem and all 3 virtus that I had shot all had a messy grouping. You should make a video on how to fix and correct the accuracy on this gun. Personally I think the barrel needs a crown done.
Try polishing your Barrel
if pellet and slug are same weight and shot at same velocity the slug will have a higher impact its physics a slug is more aerodynamic and will slide through the atmosphere easier than a diablo shaped pellet therefore the slug will retain more energy at the longer distances than the pellet if you are hunting 60yds or less use a quality pellet at 900 to 950 fps if you are hunting further out use a slug at the same 950 its simple physics at long range slugs will out perform a pellet because pellets are designed to loose velocity quickly for a safety factor
10:15 The ballistic coefficient of a projectile has everything to do with retaining energy, literally everything. You also say that the BC changes as soon as the projectile leaves the barrel. That's utter noncense . . . every slug and pellet has it's own set ballistic coefficient, no matter at what speed you shoot them, the ballistic coefficient of that projectile never changes, it doesn't decrease nor will it increase. It is a SET number, otherwise they couldn't print the BC on the box. The only projectile that I know of that could changed it's BC during flight was the French Concorde when it lifted the cockpit.
Advertised BC is predetermined. It isn't specific to your rifle, your fps settings etc as you imply.
To achieve the "Advertised" BC you have to fire the bullet at a specific FPS from a specific barrel length and ROT.
James I totally agree with you my friend if I want to shoot real far yardage I would shoot a powder gun. I get great results with pellets so why go to slugs when there more money and you get less.
Thanks!
You dont get less slugs maintain velocity better down range and have much deeper hollow point allowing for more stopping power at range.
Very little reason to shoot slugs slow. They will lack expansion at those speeds. Unless they are very soft.
I have a video planned to show slug expansion...
Bc at 800 is better or worse at 1000? More resistance. Cast bullets all seem to vary by speed. Yaw makes them freeky. I used to watch some spiral and drop more. Then others flew strait and dropped less. You think alot. Keep it up bro!
My personal take on this is thats its very much up to what applic🎉ation the ammo is needed for. Hard to say wich is generally better.just my opinion.👍🇸🇪🔫
You do not understand BC. The BC is fixed for a projectile. The only way the BC can change is if the weight changes or shape changes. After the projectile leaves the barrel, the weight and shape is fixed.
You seem to conflate accuracy with amount of drop.... Muzzle velocity is key to controlling drop, while tuning the settings for the ammo is key to accuracy.
If something cannot be shot at High velocity/energy its pointles to shoot. For plinking what ever but for hunting you need energy
Maybe because I'm newer to taking air rifle shooting as a jobby and not just something I had in the closet and I know this video is a year old but I'm kind of not understanding what is shown here.
Two different weight projectiles fired at two different velocities hit at two different spots.. wasn't that to be expected right from the get-go before firing the first time? I'm not understanding the truth that was revealed.
Pellets increase BC downrange (800 to 600fps are the best velocity) and Slugs decrease BC as they go downrange (at muzzle is the highest BC the slug will ever have)
pelet: faster straighter balistic on smaller distance, slug: slower but more total kinetic energy due to being slower it get more time to store kinetic in the barel; so more drop but much more predictable drop... and usable distance increased and hit energy at long range increase.. 20+ joule go for heavy pelet or slug (slug more heavy best suited for powerfull airgun... cheap diana old 7.5j : go cheap ligh ... expansive new powerfull airgun? do u really want ur piston hard hit end travel while shoting cheap light pelet? ... )
if the pelet exit too soon... there is nothing to keep that presure in the barrel to get air shock absorb of the piston at end travel ...
It's all "slugs" or "bullets" for me, since they are far cheaper than pellets. I just buy Lee bullet mold (around $30 on ebay) and cast all my 357/9mm bullets. All I need is lead to make my slugs/bullets. And they work great for my .357 air guns. If you can recover the lead after shooting, then you can recycle them and make new ones from used bullets, so net cost of my 357 slug/bullets is almost nothing, making my 357 air gun even cheaper to shoot than .22 pellets or even .177 pellets.
So what kind of ft lbs do you think it would take to send a slug downrange 100 yds. On target. May not be pinpoint of course. But kill shot ...
Wow what are you smoking of course the pellets will impact higher because They have a higher muzzle velocity less drop
Smoking the truth? If you know what I know @6:00
He did stop short of saying they drop more because they are heavier, few of the comments are still thinking that though.

Cool!

Hey man not to wreck your video but you are wrong about many things. Understanding ballistics and saying you know what your are talking about and using this video as proof doesn’t make you right. In order to compare the ballistics of a pellet vs slug you need to shoot them at similar velocity. This is like comparing a 556 to a 45-70 cartridge. Of course the 556 will shoot higher faster because it shoots faster right out the barrel. Pellets skirts slow down the projectile compared to slugs. You don’t believe me then shoot the slug at the same speed as the pellet and put a chrono down range. You’ll change your mind. Slugs are for hunting and they are better than pellets. This is coming from someone who shoots mostly pellets. I’ve shot slugs out of my fx and the faster you get them the better they perform.
I've shot them at similar velocities and my shooting speaks for itself...cards, aspirins off balloons sub moa groups @100yd, I've done it all man....pretty sure I'd know as I shoot both pellets and slugs very very accurately and since this video I can leave the gun on same settings and now I am up to 6 different slugs all sub moa bub so
That has nothing to do with how ballistics work. Shooting accurately with them and knowing that slugs shot at the same speed as pellets will result in better long distance performance is 2 different things. Just because a pellet you shoot “outperforms” a slug that you’ve tested doesn’t make what you said true. Some guns aren’t really made to produce great results with slugs because the speeds needed to be effective are much higher than they can achieve. The fact of the matter is that slugs will outperform any pellet in drop and wind drift. Comparing a 900 fps pellet vs a 780 fps slugs is like comparing a 9mm vs 380 in speed. Plug your info for your pellet into any ballistic software and then for the slug you were using and then use the same fps for both and I’d place money that the slug will outperform the pellet in every condition. You can’t deny physics and what you are saying is just not possible. Sure you might can get better groups with a pellet sometimes but holding the same point of aim for each shot slugs running the same fps will drift less than pellets.
Slugs need more velosity 930_1000fps to make it perfect acurate
That article said the exact opposite….
A?.
Don't bullet manufacturers take into consideration the twist rate of the rifling in the kind of rifles they're developing a round for as well as the length of the barrel and a bunch of other parameters like how long the slug has to be to be stable in flight?
I feel like pellet manufacturers have just squashed some lead into the shape of a bullet and put it out there for people to buy, Air rifle pellets are both drag and spin stabilised and have been working well for like a century now,, many people can't access rifles capable of pushing these things fast enough for it to make sense,, we all wish that we could though
I've done some unscientific testing into 3/4" yellow pine boards at 25 yards and I've came to the conclusion BC numbers are more BS than anything, at least in regards to air rifle pellets. My test rifle was/is a .22 Diana 350 Magnum, the pellets I used in my tests included the Crosman 14.3gr HP, H&N 14.66gr FTT with a claimed BC of .019, Barracuda Match 21.14gr with a claimed BC of .039,Norma 15.9gr, Norma 17.6 gr with a claimed BC of .023, Baracuda Hunter Extreme with a claimed BC of .027 and last but not least the Daisy Hollow Points. Of all these, which one do you think fully penetrated the board? The Daisy Hollow Points did. Unless Daisy is making their pellets using some secret outer space material, these results seem counter intuitive, just sayin.

@Renegadebroadcasting Renegadebroadcasting you canadian
'pellet had a higher impact even though it had a higher muzzle velocity' - yes, it would. If you propel a lighter projectile with the same force as a heavier projectile, the lighter will travel faster and, if within range, reach your target with less evident drop as it got there quicker. You're comparing 800 fps slugs to 950 fps pellets... Why? What grain weights? What FPE at point of impact?
A 30% increase in mass will add significant drop.

Airgun Slug Vs Airgun Pellet - WHICH IS FASTEST?
This is worth a watch it shows that pellets are impacting slower every time at the target. The slugs are hitting faster then the pellets.
I think you need to see if the slug is spiraling. If it is then it isn’t efficient in flight . Also , what is the diameter of the Diabolo pellet vs. the slug . Your barrel may favor the Diabolo over the slug .
I’m happy for you if you like the Diabolo pellets but for me the slug is the way to go .
It's not spiraling...flies true on target, I can see my projectiles in flight at this velocity and setting, I find out the trajectory of each projectile and have my own tuning methods other than velocity to correct the impact/groups ...I hit/split cards at low velocities at 100yd all the time with pellets
@@ALLABOUTAIRGUNS the slug design is still evolving where the the Diabolo design pellet has reached its Plateau .

Also even if a pellet increases BC it starts far far lower and wont ever reach the slug BC so I think that’s not much or a win for a pellet either. Pellets are excellent at close to mid range, slugs are the future and long range performers
Have you seen what I can do with pellets? Either way pellets or slugs you really have to know what you are doing if you want the most out of them...I am a precision shooter, I don't shoot at random sized targets...I shoot at playing cards on edge all the way out to 200yd consistently...and pencils with pellets freehand standing out 200yd...besides that price per quantity and pellets are known to be more accurate even though I am able to shoot slugs that good
The ballistic advantage of a slug did not take place in the shooting range of a pellet rifle
First, I don't trust the opinion of anyone who puts their head in the center of the screen on a video like a first-week newb. Second, you can come up with all of the reasons you can imagine for an airgun being superior to a firearm, but you can't explain to me why they aren't used by any military or police force. They are a NOVELTY, a fallback for when there is no ammo available and you haven't learned to reload. I own three air rifles, a .22, .25 and a .30 cal, but I totally HATE them.
不好意思不懂英文，能告诉那种子弹远距离好点？
You’ve seen this already commented but I’ll say it again. You have to compare same grain weight 15.89 with no power change will obviously hit higher than a 21 grain, you should know this. In addition, the barrel of the rifle makes contact with 70% or more of the slugs whereas it only makes contact with 20% of the pellet which means more drag from the slug. Measure same grain dude slug will be a bit slower cuz of drag but this is terrible what you did. Usually like you content but this one is ridiculous
If you’re shooting more than 75y you’re pellets will shoot DRASTICALLY worse than a slug could on it’s worst day.
Oh a year ago you did a video 21gr pellet vs 21gr slug. Watch that everyone
the test ist wrong, you have to shoot both at the same speed
its just an opinion of one person. Not the truth.
I had to smile when he hit the aspirin, that was very impressive.
Thanks !
Slugs are like bullets so no Wonder they drop like bullets. Thats why you need speed. And you hit like a truck
Awesome vid man and again I've said before but we're I'm guessing an hour or less away we need to meet up ill bring my 357 terminator hpss plus and many other guns
Send me an email shoottokilloutdoors@gmail.com and we'll have to plan to get together and shoot!
I wish my gun shot 800fps fuck. It came in shootingjust under 500 butni had to tune it to get it up to 600 and thats the absolute most i can get for .25cal in my country
At first I was way skeptical because of all the hype around slugs. But, you convinced me. I was sold on the price discrepancy alone. And fuckin' fantastic shooting my friend. Subscribed!
Thanks!
Wrong again dude...slugs have more drag in the barrel and your comparison is with a much heavier slug. I've shot thousands of varmints out past 150yds with an airgun and I can tell you 100% for sure that pellets are less accurate and have less energy at that range. The BC of a projectile does not ever change.
The only way to truly do this test is if both projectiles are shot at the same speed. With close to a 150fps difference there is no way to compare the two. This is a total waste of time to watch!
I did shoot both at same velocity as a side note and pellets were 1" lower impact at same weight on this same target/distance...point is to fully understand trajectory and I do
Your graphic is confusing because when ballistic coefficient increases or is "high", and become more efficient, the number gets bigger and the drag is less, so the projectile coasts to the target more efficiently. When the ballistic coefficient decreases the number gets smaller, the efficiency is less and drag is increased.
So a pellet has a decreased ballistic coefficient and a slug has an increased ballistic coefficient. But the drag of the projectile is greater on the pellet meaning it looses energy sooner as it travels to the target.
Projectiles have many BC's depending on velocity and uniformity of the projectile. This is why Sierra lists 3 or 4 BC's depending on velocity.
yes, that's why I pinned the article in the comments here so people who are interested can read about it
if you put the best air rifle in the hands of an idiot,the idiot aint gonna hit anything.😂😂😂😂
Slugs like to go 1000+ fps pellets don’t give af
The bc of the slugs isn't enough to over come the faster speeds of the pellets at one hundred yards. Try going out to 150 or 200 yards. The other advantage of slugs is less wind drift, though once again air gun slug bc 's aren't in the same ball park as center fire rifle modern projectiles. Time to target vs gravity = verticle drop. One of the constants in shooting.
@ 9:58 that's what I said...you're right can't compare centerfire to airgun ammo but 22LR isnt centerfire it's rimfire which is more of a slug/pellet combo due to the way it swages to the bore and is shot in the pellet/slug velocity, if you the read article I pinned it clearly states pellets are more accurate than slugs (spin drift/stabilization due to BC decreasing in flight)
He is comparing a 15gr pellet to a 21gr slug lol if used a 15gr slug it would kick the pellets butt… now accuracy pellet are more accurate but if you find the right slug just like you have to find the right pellet slug all day long
@@bushwhookie1334 If you slow down the same weight pellet it’s going to hit lower at the same distance. If you speed up the same pellet it should hit higher. Shoot the pellet and slug at the same speed and see what happens as long as the gun shoots slugs good.My Umerex Origin .22 I tried several different slugs in it and it did not like any of them.
@@fathertimencUSA I have a hatsan .25 flash. Shooting 34gr slug and 33.95gr mk2 pellets the slug is higher because of the BC.. now if your gun don’t shoot slugs good then there is two things the rifling is not good for slugs or your slugs are to lose say .217 air is going over it need a .218 .219 if that don’t work stick to pellets
@@bushwhookie1334 Yes they are the same weight basically. The slug might be going a little slower because of the more surface area against the barrel but probably not as much the weight difference he is using where the pellet is going a significant fps faster than the slug. Even with the better BC of the slug if it is going a significant amount slower and has more weight of course it will group lower than the lighter faster pellet. But range would also play a part since pellets slow down faster than slugs because of their BC.
When a keyboard warrior thinks the understands something. Higher muzzle velocity means projectiles go farther faster. Higher bc means projectiles retain velocity longer and therefore travel farther. You didnt have good groups. Your groups were dogshit. The faster a projectile goes and the heavier it is the more energy it has so higher a higher bc means more energy is retained at a distance which means the bc is directly related to energy retainment.
Whew!! Nightmare of a video.
I'm sorry this guy is clueless he shouldn't be advising anybody about her what to shoot. Pellets and slugs are two different creatures. If shot at the same speed a pellet will bleed off its speed so much faster just because of the BC compared to a slug which has a better BC if shot at the same speed the slug will retain speed and energy @ a longer distance. He can't even explain why the slug is shooting slower than the
Let me explain why the slug came out, #1 the slug is heavier than, #2 because the slug has a longer surface that rides the barrel rifling, this creates friction does reducing the speed of the slug.
But if you were able to tune the slug to shoot the same speed as the pallet the slug will always out shoot the pellet
logical sense??
Yeah if I'm getting pellets to shoot good as slugs all the way up to 200 yards without the extra cost and makes perfect logical sense... especially since pellets are known to be more accurate and my shooting proves that but I also can shoot slugs very good
James either your thoughts on ballistics are severely flawed or you just don't know how to express what you're thinking properly
Shoot at what the guns like true but Also calculate the weight my brother
these same shots I used as an example @100yd I have done with pellets @800fps at the muzzle with my tuning methods....I calculate by the trajectory
This guy serious?
This video is extremely confused. Theres so much more at play. Slugs are for hunting price wise. Order 1000 slugs at a time bud.
I stopped after a couple minutes because I really don’t think he understands bc.
You’re always going against the contrary witch is fine I’m not knocking you it’s just a trend I noticed with you interesting viewpoint.
Ballistic Coefficient (BC) is a figure of merit for the shape of a projectile. Since the projectile's shape does not change during flight, therefore the BC of the projectile also remains constant, regardless of whether the projectile is down range or right next to the muzzle..... or even if it is inside the box it came in when you bought it.
en.wikipedia.org/wiki/Ballistic_coefficient
The difference between the 2 projectiles' drop is due to the time of flight (as many have already pointed out in the comments). Go faster and the drop is less, go slower and you get more drop.
BC changes consistently because the projectile velocity at range changes consistently and therefore the BC changes as well:
A drag coefficient can also be calculated mathematically:
Cd = 8/ρv^2πd^2
where:
Cd, drag coefficient.
ρ density of the projectile.
v, projectile velocity at range.
π (pi) = 3.14159…
d, measured cross section (diameter) of projectile
It's right in the Wiki definition you posted.
Great info bro and nice shooting
Thanks man!
