I love your videos and apparently my grandson does too. He’s 6 months old. Every time I watch your podcast videos he calms down and stares at the tv until he eventually falls asleep. You have taken babysitting to a new level. Thank you.
haha so cool. I think he is absorbing some of your calming energy too, just an idea though. You get nice and relaxed and calm when you sit down to watch and learn with Spomer. heck I do too. And the little guy can feel it too. And, voila! Sleepy time!
Another great video Ron, really enjoy your work! Warmest winter that I can remember here in New England, western Massachusetts to be exact. No snow, lots of rain and a lot of lakes haven't even frozen over.
Thank you Ron for the always good information on cartridges and their performance as well as just good plain talk about hunting, conservation and the shooting sports in general. It might be cold right now where you are at but Spring is coming. Have a great week.
Thanks for addressing my comment Ron, you’re the best. Anyway, I didn’t mean that the bones and offal and whatnot shouldn’t be left in the field, you’re absolutely right about that. I only meant that I feel badly about not getting everything out of what I have before then cycling what’s left back to nature. I also always put the bones in the compost.
Hornady uses temperature stable powders, for extreme temperature variations the outfitters line is designed specifically to work anywhere in any conditions including having sealed bullet and primer so you can drop it in the river without worry.
Hi Ron. Great podcost. Getting back to the twist rate: The powder in any given cartridge only produces so much energy. Some of that energy gets converted into heat, sound, and into the motion of the bullet, that motion being linear - straight down the barrel, and rotational - bullet spin from the rifling. So, by increasing the twist rate, resulting in more spin, what is being sacrificed, linear velocity? Heat? Sound? There's no such thing as free in physics, so by adding more spin with the same amount of powder, there must be someting getting less. Thanks for your great channel, and I look forward to your reply.
Great videos and great information. I have had hang fires and miss fires in outside air temperatures at -30F and below with the standard primers, so I went to magnum primers and solved the problem. The top end of the standard primers and low end of the magnum primers are very close, so the probability of over pressures is minimal. Have a great day!!!
Hi Ron, interesting listen to the answer of the shooting in extreme cold temperatures, I live in northern Alberta and hunt moose and elk late in the season usually and hunt quite often at temperatures of -30 to -40C. My cartridge of choice is 7mm Remington Magnum I also use 7mm08 and 338 federal. I'm not a long range shooter, I prefer to sneak as close as possible so most shots are within 300yds. Yes the cold does POI but what I do is keep my ammo in my pocket lol, yep keep it warm and load mag primers in 7mm08 and the 338 federal. There's a few other challenges with hunting during cold weather but that's another topic, live the show keep up the great work. Tony.
@@waynemayle865 you may be right but the older gentleman who was introducing me to reloading was a multi millionaire who owned thousands of acres adjacent to the pisgah national forest and had many custom made rifles,,his name was Grover Honeycutt,,,and so I may have miss calculated the exact year this went down.
Talking temperatures- I had once had my 7mm-08 fail to fire even though the primer was struck well. At the time it was a -5F morning. But should I be worried that it may discharge after that? Should I wait a couple of minutes like I did? I left the Buck go that morning to be safe because I didn’t know?
Hadley, I've never had a dud like that explode seconds after the initial primer strike, but I believe it can/has happened. Think of it this way. Primers ignite due to pressure, not heat. Powders ignite due to heat. So, if the firing pin strike doesn't ignite the primer, it can't eventually warm up and ignite the powder. However, I'm thinking perhaps the primer smolders or heats sufficiently for the closest powder grains to smolder and eventually ignite. Results: a hang fire. I've often cycled rounds out of battery after a failed ignition with no issues, but that doesn't mean someone once had a partially extracted cartridge go off. Anyone care to chime in?
The marrow is quite delicious and really comes alive if you split and roast them first. It is actually more delicate than beef marrow so I find cooking it down by at least half volume and as rich as 1/4 volume if you start by just covering with water and stewing covered at a low boil for as much as two hours.
Correct about cold air density vs warm air density. Simple analogy is a baseball hit it the hot July and August nights in Texas , will travel farther than one hit in mid April in the mid 50's in New York.
Boat tail bullets. My only problem with bt bullets was in my TC Contender 7mm TCU with a Nosler 120 boattail. 3 powders and a few charge weights each cured me of using lighter bt bullets in it. It shoots 120 Vmax flat base ok and 130 Sierra SSP great. Tested the chamber attempting to find rifling with the 130 SSPs. The bullet is too short. Apparently this mid/late 1980s TC brand 10” barrel is designed for longer/heavier bullets and has a lot of free bore. The Hornady 139gr also shoots very accurately. Enjoyed this episode, keep up the good work!!!
We always hang the Deer fat in the bushes around the Deer camp, you should see the birds after a few days, Fat and happy! I’ve had Jays and Chickadees land on big game animals while I’m gutting and loudly and excitedly chirp and make a fuss. Its wonderful.
Hi Ron, love your videos and knowledge. I was wondering what you may think/know of regressive reloading. I heard that some shooters are simply popping out and replacing old primers of cleaned cases luring in powder and pressing in new projectiles without reshaping or resizing cartridges to save time and money one reloaded cases.
Salty, the only way that would work, to my knowledge, is with extremely low-pressure loads that don't stress/stretch the case. And the bullets would likely not fit snugly enough. An old reloading technique for making practice rounds for revolver shooters was to deprime, reprime, and seat a plastic bullet. Primer alone drives out the plastic slug. Normally cartridges need to develope sufficient pressure to expand the brass neck or mouth (at least) sufficiently to seal gases from coming back into the chamber. Usually the rest of the case down to the head/webbing stretches to fill the chamber tightly, too. In a micro second they shrink enough for easy extraction, so you can often get by neck sizing only. This gives a tight fit with fired brass in chamber, but usually means the same rifle, same chamber. You've roughly custom sized the brass to your rifle's chamber. But you still need to size the neck back down to grip the bullet. When I build low-power, low-recoil plinking/small game loads for my 30-06, etc., I still need to neck resize. Necks are usually quite carbon fouled after firing, too.
Over a Lab Radar, I get 2800 fps from the 180gr Accubond in my 338-06 and the same from the 200gr Accubond in my 338-06AI. The standard took my biggest whitetail in MO and a nice 6x6 NM bull elk. Both are much lighter and easier to carry than my 338WM, but I still prefer the magnum when travelling to Alaska.
Jamie from Australia. I think ron didn’t understand what you meant by twist rate affecting velocity. I don’t know myself if a higher twist rate slows down your bullets. But I’m sure you might be able to find out. Im sure it’s explained in a video somewhere. Now curious myself. I’m going to look too.
interesting. For things like that I feel like and I’d bet that there’s some sort of equivalency equation maths one could perform to find out. Not a mathematician or physicist of any sort but just thinking of old algebra and finance equations I learned in high school and college. Hypothetically, like, velocity(x)=twist rate(y). and then it varies in between. Again totally spitballin’ on that one, just a guess. A great idea to find out!
Adam, it makes sense that the added friction of a faster rifling twist would increase resistance and raise pressures. You could also say fast twist would slow a bullet. But I'm thinking one creates loads to safe pressure limits regardless, in which case one gets his highest safe velocity with that combination. I haven't seen any handloading manuals recommending loading down for fast twist barrels.
@@RonSpomerOutdoors-Podcast ok. Great point Ron. Thanks for the info. I was thinking along the the line of having two identical rifles firing the exact same load. Only one barrel has a fast twist and the other a slower twist. I just think comparisons with everything else being equal that the fast twist might have a little lower velocity at the muzzle. I like to learn anything i can. That’s why i like your show so much. A lot of good useful information that hunters and shooters should love.
Your explanation of the cold air trajectory seems in line. But, having spent all summer in the Tennessee climate working up loads for elk season in Colorado, I have found that elevation and humidity have a bigger impact on bullet trajectory than temperature. Your thoughts?
Elevation is air density: in meters, sea level is (mmHg) 760 at 2400 it's 564. While temperatures definitely affect air density, the effect isn't as great as the elevation change.
Elevation and humidity work on trajectory the same as cold does -- they modify air density. Elevation means less air pressure, but it usually also means cooler temps, so the two offset to a degree. Humidity makes the air less dense, too, which seems odd, but is proven. Fortunately, none of these factors is significant until beyond 300 yards for big game hunting. Ballistic calculators can figure them out and give you corrections. They are needed for extreme range target shooting.
Something to think about in cold weather is the impact of cold on barrel steel. Cold causes steel to contract thus generating more resistance which impacts velocity. While heat causes steel to expand. This is why 1st cold shots out of a rifle are slower in velocity than a heated up barrel.
If boat tail bullets don't shoot well from a rifle the first thing I would check is the crown of the rifle barrel. Even the slightest imperfection in the crown can cause yaw in a boat tail bullet.
Faster twist rate barrels absolutely restrict how fast you can launch a bullet of a given weight from a barrel. Nobody talks about it much, but the standard twist rates were always a compromise that would stabilize the heaviest (longest) bullets commonly available in a given caliber, while still allowing good velocity from lighter bullets. Also, sometimes a boat-tail bullet is just long enough to not stabilize well in a given barrel, whereas a flat-base bullet of the same weight often will. I've seen it a couple of times with wildcat cartridges built using a barrel previously chambered in a different cartridge.
what does someone like you with that level of knowledge think of that 8.6 blackout in a 1:3 twist barrel? Just curious, I am a total newbie to all this type of stuff.
@@nozrep - The only reason you would go with such a fast twist rate is to stabilize bullets that are very long and heavy for the caliber. I have seen how these bullets are supposed to perform and I find them to be a solution in search of a problem. Many cartridges are coming into existence because they fit the AR-15 platform. For my money, if I wanted an AR shooting .338" bullets, I'd just get an AR-10 in 338 Federal. No absurdly fast twist barrels or gimmicky bullets needed.
@@jasonbroom7147 yes thank you! i like that idea too! haha yes I just saw a Kentucky Ballistics video doing a 300 Win in an ar10 platform and am thinking, want want want want. Haha and also I had seen before a 30-06 in an AR10 somewhere on the videos that was super cool also. Alas… money. So I gotta stick with a .308 or.223 for my “starter” ar as I have only ever shot bolts and levers and shotguns for hunting.
States that allow hunting during the rut will affect the breeding of the does. Studies have shown in those areas the small bucks breed more does than the big old guys. The old guys are hiding more often than not.
Hi I enjoy your video there is so much good information . I have a question is the 270 win ammunition still available out there here there is no we're to be fond I m just wondering ?
I’m in the middle of va and that has always been a caliber that is most of time on the shelf 270win, 30-06, 308, 30-30. My grandfather only ever used a 270 my brother uses his actual gun now my dad use to as well and I take his old 270 out one or two times a year and to be honest I love it iv taken black bear white tales I would take that gun any where in the world and truck my life to it to do the job as long as I do my part love hearing people keep the 270 alive
It's more complicated to order ammo online here in Canada and yeah the 270 win use to be the most popular ammo around here but not right now I could even find a die for reloding for long time finely I got one
I could use some help deciding a caliber for white tail hunting I used a friend's 6.5 creedmoor this past year but I'm trying to decide what caliber I want but I don't want to damage to much meat any recommendations and do you think rib meat is worth it on kansas whitetail
"Worth it" for rib meat is up to each individual. I've never bothered with it, but some do. As for KS calibers, there are literally dozens that will suffice. It's tough to beat a 7mm-08, 270 Win., 308 Win, 260 Rem., 6.5 PRC, 6.5 CM, or something similar. I've also had excellent results in KS whitetails with 25-06, 243, 6mm Rem., 22-250 AI, 300 Win Mag., 30-06, 280 AI and many more.
After 3 years of intensive study, I have concluded that the internet opinions cause a significant drop in projectile performance. Anxiety sets in and they just don't have enough lead in their pencil to perform.
Love this video. One of my friends has a 270 Sherman and he really likes it. He tried talking me into doing it with one of my 270s. But to me all the xtra case work isn’t worth it. I’d just shoot a mag round such as my 270 WBY. He really likes playing with 270 cal rifles. He has several 270 WSM rifles and recently barreled one in a 270/ 300 win mag that really woops my loads that where hot for my 270 WBY. What I’d really like to play with next would be a 280 AI. What’s your opinion on the 280 AI or the 270 AI.
I've used the 280 AI since 1991 to take elk, moose, sheep, coyotes, mule deer, whitetails... Fantastic tound hot on the heels of 7mm Rem Mag performance in a 30-06 size case. And now you can get factory ammo. Much more convenient than any wildcat.
I was almost fooled. They pretended they were you Ron. They had me winning a $3000 bow. All I had to do is send them $200 for shipping asking for my credit card number. Caught on to them with the credit card request.
we have a semi-tame semi-wild mutt cat at our deer lease that always just… appears out of nowhere and meows at us while we gut our deer. Next day he’s always covered in guts and blood from “diving” into the guts and bones hole we have dug and pour everything into after dressing at the gutting station. One of the nicest danged cats I ever met. Tries to rub up on you like they do. But yuck covered in deer guts from gorging on deer bits all night long😂. Hahaha nothing goes to waste!
Alas, roaming feral cats like that are a major drain on songbirds, quail, rabbits. Invasive species. Would be great if you could lure it indoors and keep it there.
Ron your correct the tallow and fat removed is the proper way to butcher my wife seasons the venison and you would never know the difference between ground beef it’s fantastic most people don’t butcher and clean properly then they say it’s Gamy
The question about temperature reminds me of an exchange in Ice Station Zebra: Capt. Anders: A bullet goes just as fast up here [the Arctic] as it does down there. [Southeast Asia] Jones: ot quite. An insignificant difference, perhaps, but I think you'll find the operational characteristics of the M-16 indicate that a bullet will decelerate as much as forty feet per second per second faster in these climate conditions. It's denser air, you know.
I believe the reason the 338-06 is far from .338 win. mag. is that the 338 diameter hasn't gotten big enough to be able to use the faster burning powders that can be used in a 35 caliber. The reason the 35 Whelen can reach such high velocities and energy levels is because it uses powders that aren't used in smaller bore diameters. For that reason the 35 Whelen can come much closer to .338 levels and by using much less powder. The .358 Winchester is another example of this. If the .338-06 is compared to its parent case the 30-06 then the 338 increased the values of its parent by a fair amount.
The other thing that could happen with a 168 grain 7mm if it was a very slow twist rate or if he was using a very long bullet perhaps a monolithic bullet he could just be to long for his rifling. Remember it's the length to diameter that matters. For the .338-06 and other times you increase bore size the rifle is becoming more powerful. The area that the gas can push against is how the energy is transferred and for a given barrel length you will get more power out of the same volume. It will also provide better performance with a shorter barrel since you have the same amount of gas going into a higher volume bore. You actually get one more advantage and this could reflect on your cold weather question as well. As the bore size increases the ratio of bore area to surface will drop. That surface area will be sucking heat out of the gas. That is a parasitic loss. Heat and pressure are basically the same and you can really only get your powder to burn and keep producing gas when the pressure is high enough to sustain your burn speed. After that the pressure and heet will drop as the bullet moves down the bore and creates more room for the gas. Any heat lost into the barrel will drop your pressure at a faster rate. Heat transfer happens faster at higher pressure and different alloys have different rates of heat conduction. I have read that the brass case can actually soak up 40% of the energy of the powder column. This transfer is really complex and even the heat treatment of a metal will affect the speed of this transfer but when all of those surfaces are cold it's going to take some amount of increased energy from the glasses. Cold also slows chemical reactions and this is where modern powders are doing a better job of getting a more consistent range for a stable burn rates. It's my understanding this was a bigger problem in slower burning high energy powders. Single base powders that are nitrocellulose based do well across a large range of temperature. Slower powders are used to develop higher velocity. Because they are slower the bullet can begin to move forward and create more volume and allows you to use more powder without excess pressure. To help develop more speed they also design them to have a higher energy content and di this by adding nitroglycerin. This makes them a double base powder. It's the nitroglycerin that has problems at lower temperature and newer formulas are able to mitigate some of the losses. I have read that some of these are actually triple base powders. These used to only be used in cannon and gun rounds for military use use. For your Canadian hunter if he is really worried there may be advantages to using larger bore cartridges. With the larger bore size they use faster powders already. This is another reason they do better with shorter barrels since there is a trade-off with slower powders where it takes longer to get to peak pressure where you will get faster acceleration making better use if the full barrel length. Since I am going on about internal ballistics I want to say that one thing that you don't hear as being a downside to faster riflings is that it will increase friction and some energy will be wasted although the amount is small. I am really seeing internal ballistics as being somewhat overlooked for most shooters and am trying to understand it better. If anyone knows if any good references that I could get my hands on I really want to study this more and have hopes of doing some gun design. I think some really interesting guns could be developed if we could start using gain twist rifling and sabots. This could make medium bore or even large bore rifles really useful since we could get by with nice short barrels but still have fast enough twist speeds to stabilize popular long range calibers. It even gets better if ultra high pressure cartridges become common.
Cold weather does make the air denser and high altitude make it thinner. .I always thought it was the lower velocity in cold weather more than air density. Be interesting to see someone do the calculations for wind resistance, that is beyond my ability to do.
Does temperature affect ballistic performance? The answer is yes, it does. Does it have a big effect? Not really. According to the QuickLOAD internal ballistics software (which employs a thermodynamic model for simulating the combustion of the powder inside the barrel) nearly all commercial powders exhibit some temperature sensitivity to burn rate and pressure. Typically, one can expect a variation in muzzle velocity of 1-2 ft/sec per degree F of ambient temperature difference, depending on the specific load. In addition, there are published correlations that show how to correct the published G1 ballistic coefficient for temperature, atmospheric pressure, altitude, and humidity deviations from the "standard conditions" that the published BCs are defined at (see, for example, the external ballistics section in the Sierra Reloading Manual, 3rd Edition, which is the one I have). Of all these factors, humidity is probably the one variable that has the least effect on BC, but it's interesting to play around with these models just to see how small these effects are. In my opinion, the biggest uncertainty in long range shooting (beyond 400 yards or so) is the unknown wind variation downrange, and whether you are shooting uphill or downhill, especially for steep angles. Not every hunter carries with them a laser rangefinder that corrects for shooting angle (although maybe they should). The other big factor in long range shooting is cant. You must hold your rifle as nearly perfectly upright and vertical as you can. Any clockwise rotation of your rifle so that the plane formed by the line of sight and bore axis is not vertical will tend to throw your bullet off target. This is not a big factor inside 100 yards, but it could be a big factor beyond 400 yards. When shooting at a living creature, it's always a good idea to stalk as close as possible to your game to ensure an ethical shot. Just my opinions...
i have no idea what you are talking about because I am not a long range shooter of any sort. Regardless, I like your opinions and have learned, just from that!
Suppose years from now your living in space. You have a target set up on the moon. How do you figure your windage? There may be no air , but there are gravitational fields. No bullet drop though. I was just wondering?
You'd need to know the gravitational attraction, air density, and compute from there for drop. With minimal or no atmosphere, their could be no wind, so no correction needed there. Without atmosphere, a bullet departing at 3,000 fps would maintain that velocity, so fly a lot farther downrange before gravity pulled it to ground.
Cold air drops chamber/ bore pressure a varied amount as it becomes colder, the pressure drops more. However the cold air itself actually allows for less air resistance and friction on the bullet because it is less dense and USUALLY has far less humidity than warm air does,so the air becomes thinner ever so slightly. So it will not get as much velocity,but what it does get will carry further ,with less drop,however marginal it is or isn't. The longest range hunters ,match shooters and similar , at 1000 yards and beyond ,they will notice the difference. The rest of us, probably won't unless you are in -60 ° f .
That's interesting, Corey. I've never heard that cold air drops chamber pressure. Unless you mean that a cold cartridge filled with temperature sensitive powder (that burns with less heat/intensity when cold) produces less chamber pressure. I think that would be accurate. But there are many powders now that show little change with temperature. That is a fine solution to maintain muzzle velocity. But every scientist, meteorologist, and pilot I've consulted informed me cold air is more dense than warm air, thus drag increases, thus trajectory suffers. You are correct that increased humidity reduces air density slightly, so it can offset the density of colder air slightly. Fire a 150-gr. bullet, B.C. .48, 3,000 fps MV, zeroed for 100 yards, and at 90-degrees F. , 50% humidity, it will drop 45 inches at 500 yards. Keep all parameters the same except change temp. to -20-degrees F., and drop at 500 yards will be 49 inches. This is with out changing the cartridge/powder temperature. All trajectory change is result of different air density. Shoot the same bullet at the same MV with a consistent ambient temperature but change the humidity from 10% to 90% and the drop difference at 500 yards will be just 0.10" -- a tenth of an inch. The bullet shoots a whole 1/10th inch flatter at 90% humidity. At 1,000 yards the difference is about 1.5 inches.
Not sure if cold temperature affects the powder/propellant... but cold air is denser than warm air . Still don't think it would make a difference unless it is at extreme distance. 🤔
Yup, life is hard on youtube: tons of commercials, with their algorithm apparently still thinking I have a big head of long blonde curly hair and also need tons of makeup; which is ridiculous for an old fart like me ;-) And with every comment I make I win great prizes ofcourse. In the meantime, just about all the channels to which I subscribe suffer from UA-cam meddling with their content through strikes and whatnot. Nevertheless, I still really enjoy your vids sir 👍
My deer bones don’t get wasted, my mastiffs just eat them. Those little whitetail bones don’t have a chance against a 200 pound dog, it’s the only way I can afford to give her something to chew on as all the regular large dog toys are destroyed in a few minutes. Watching a $40 toy get shredded makes the wallet sore, even the heavy duty rubber “Kong” brand toys only last a few days.
Altitude, baseline barometric pressure, temperature and humidity all effect air density. Precise ballistics calculators need all that info to predict the bullet drop. Aircraft use the term "density altitude" to describe current conditions compared to the conditions used for the "standard atmosphere".
These scammers are everywhere sadly! QUESTION: Ron, if you were like me and from the midwest and considering deer hunting out west in northern Idaho or Montana where there are very big grizzly's that can kill you, what size of a rifle would you carry that can both kill a deer and as a second choice stop a bear or would you use a pistol, etc? I'm wondering if the .308 or 7mm.08 would work in a pinch? I know Bear hunters typically use huge 45.70's, etc.. 44 mags, etc.. which is fine, but I want to be able to shoot a deer at distance.. ? Thanks for all you do sir! God speed. Tim
I've never wanted to lug around a revolver big enough to stop a griz, so depend on deep penetrating bullets in my deer/elk rifle. A 200-gr. in 308 will penetrate darn well and with griz you need to hit major structural bone and, ideally, central nervous system to stop a charge anyway. This idea that a 500-grain anything to the chest will stop is largely wishful thinking. Sometimes you get lucky, but most times they take a licking and keep on chewing. You. Most of our griz attacks come fast and unannounced. Bear spray really does work, but only if you're upwind of the bear and you can unleash the spray in a few seconds. Handguns are faster for those who've trained and wear them for quick use. I trust to my rifle and teammates. That might be the biggest/best defense. A partner to back you up. Especially when field dressing and packing out meat. A good all-round rifle with reach and bear punch is the 338 Win Mag. 338-06 is probably just as good on the bear, not quite the reach for long range deer. 300 mags also good. A 220-gr. or bigger should suffice.
🤠 Ron, I would have to disagree with you on what you told Nick of Minnesota! That 140 grain bullet, out of the 7mm Remington Magnum is moving 3,300 to 3,350 ft/s! In My Experience, With My Big Magnums Operating At Higher Velocities, Flat Base Bullets Stabalize Better and Shoot More Accurately Than Boattail Bullets! FACT, Not Fiction! 🕵️♂️
You are half correct the flat bullets stabilize faster for the first 3 hundred yards then after that the boat tails take over! If you watch Desert Dogs UA-cam chanel he goes over the full reason why! For most hunting a boat tail is not needed. Bullet construction is more important especially for big game like elk and bears! In my short 60+ years of hunting reloading and collecting rifles I have found this to be true!
🤠 I have 45 years of Hunting Experience under my Belt and am also an Engineer! When I am talking about "Big Magnums", Which The 7mm Remington Magnum is NOT, the same laws of physics still apply - but at much different (further) distances! You are correct in stating that the boatail bullets will stabalize further down range! But, we Don't Know exactly what range the gentleman mentioned was shooting at for his game animals, Nor do we Know the Range (Distance) at which he was sighting in at! So, we cannot Make Any "Definitive Assumptions" (Engineers Don't Make Assumptions, but Gather The Facts First) About his Statements! But, For Most People, They Aren't Shooting Much Past 300 yards for their average kill, especially in Minnesota! Thus (I do believe), based upon that information that we do have, that the gentleman that came into the gun store was telling the Truth! 🤷♂️
They, the scammers, are on almost every channel. Almost always have blatant misspellings: clam your prize; massage me for your prize, etc. I mute them and report them.
I think anyone objecting to leaving bones and other non useful game parts in the wilderness would be really shocked to see all the salmon bodies in a river.
Cold Air Kills Bullet Performance? - Season 2: Episode 89 Extreme cold temperature (not air) does not affect "bullet" performance but it does affect "cartridge" or "powder" performance by lowering the pressure of the cartridge. Velocity and energy will be decreased. Conversely hot temperature will raise cartridge pressure. You can say that bullet performance is affected by cartridge performance, but not the bullet itself. Its not the air but the temperature that affects cartridge pressure that in turn affects the bullet. If anything cold "air" is often drier and less dense so "bullet" performance should be better.
I would recommend your doing more research on this. Cold air is more dense than hot air. In denser air the bullet experiences more friction and slows down faster, thus dropping faster. From my 40 years flying in the Navy and at the Airlines hot air is thiner thus we always had to get to a faster airspeed before the thin air would provide enough lift to takeoff.
@@rbm6184 Again I go back to my flying career and takeoff calculations where density altitude is a concern. Humidity affects air density less than atmospheric pressure and temperature. The affect of more humidity is to make the air less dense. High pressure and low temperature make for denser air.
@@couespursuit7350 Yeah you are right on air density and moisture. I just had it backwards. But powder and the pressure it generates is for sure influenced by temperature and that does affect bullets. You will get a drop in bullet impacts in cold temps and maybe a rise in bullet impacts in hot temps.
I got a call the other day told me my extended warranty was about to expire, I told him I wasn't interested he said how about a free rifle from Ron Spoomer? I said sure, so he transferred me to your people, how come, they all sound like they are from India?🤣💦💦💦
Cold weather..its not ballistic instability due to hot projectiles and cold air, it's as you said it's air density. Carried to extreme barometric pressure also has an effect. Air density is part of the routine corrections for artillery. Something I haven't heard about in years is over pressure in extreme cold. I know it has happened, but personally, I always considered it an issue with the difference in temperature related expansion/contraction rates between dissimilar materials, leaving a bore to tight for the cartridge.
If someone says you won something and you have not actually entered anything then believe me you have NOT won squat. I am amazed as to how many people seem to be falling for these scams wither on the phone, mail or social media.
You should show what it would really look like to give someone a gun. I myself would be willing to receive such a gift from you for the sake of protecting your viewers. You could make a video of it so people could see what it would really look like and that anything different pops up it is a scam. Hint- Voooooooodooooooooo
oof. how old are you? are you one of those senior citizens who does not immediately assume all that stuff is internet scams and such and thus is vulnerable to scam and hacks? Sorry that happened to you. But I am sure lessoned learned. May I encourage you to be vehemently skeptical within yourself about anything like that.

Another great video Ron, really enjoy your work! Warmest winter that I can remember here in New England, western Massachusetts to be exact. No snow, lots of rain and a lot of lakes haven't even frozen over.
Thanks Mark. Another blizzard underway here. We all try to not complain because we need the snowpack for our summer moisture.

Thank you Ron for the always good information on cartridges and their performance as well as just good plain talk about hunting, conservation and the shooting sports in general. It might be cold right now where you are at but Spring is coming. Have a great week.
Thanks for addressing my comment Ron, you’re the best. Anyway, I didn’t mean that the bones and offal and whatnot shouldn’t be left in the field, you’re absolutely right about that. I only meant that I feel badly about not getting everything out of what I have before then cycling what’s left back to nature. I also always put the bones in the compost.
Hornady uses temperature stable powders, for extreme temperature variations the outfitters line is designed specifically to work anywhere in any conditions including having sealed bullet and primer so you can drop it in the river without worry.
Hi Ron. Great podcost. Getting back to the twist rate: The powder in any given cartridge only produces so much energy. Some of that energy gets converted into heat, sound, and into the motion of the bullet, that motion being linear - straight down the barrel, and rotational - bullet spin from the rifling. So, by increasing the twist rate, resulting in more spin, what is being sacrificed, linear velocity? Heat? Sound? There's no such thing as free in physics, so by adding more spin with the same amount of powder, there must be someting getting less.
Thanks for your great channel, and I look forward to your reply.
Great videos and great information. I have had hang fires and miss fires in outside air temperatures at -30F and below with the standard primers, so I went to magnum primers and solved the problem. The top end of the standard primers and low end of the magnum primers are very close, so the probability of over pressures is minimal. Have a great day!!!
Hi Ron, interesting listen to the answer of the shooting in extreme cold temperatures, I live in northern Alberta and hunt moose and elk late in the season usually and hunt quite often at temperatures of -30 to -40C. My cartridge of choice is 7mm Remington Magnum I also use 7mm08 and 338 federal. I'm not a long range shooter, I prefer to sneak as close as possible so most shots are within 300yds. Yes the cold does POI but what I do is keep my ammo in my pocket lol, yep keep it warm and load mag primers in 7mm08 and the 338 federal. There's a few other challenges with hunting during cold weather but that's another topic, live the show keep up the great work. Tony.
5:05 froghopper was talking about making a demiglace.
The 17 Remington, was the first bullet I reloaded in 1966 , I will never forget the excitement and how it made me a reloading fool for life.
I also own a 17 remington did know it was released in 66 I thought it was 70 or 71
@@waynemayle865 you may be right but the older gentleman who was introducing me to reloading was a multi millionaire who owned thousands of acres adjacent to the pisgah national forest and had many custom made rifles,,his name was Grover Honeycutt,,,and so I may have miss calculated the exact year this went down.
@@bobbygreen2291 heck yeah. Could of been a p.o. Ackley also that would of of been also to shoot back then
@@waynemayle865 first time I remember seeing a ackley improved cartridge was a friend of mine that had a 280 Remington done that way in 1993.
Talking temperatures- I had once had my 7mm-08 fail to fire even though the primer was struck well. At the time it was a -5F morning. But should I be worried that it may discharge after that? Should I wait a couple of minutes like I did? I left the Buck go that morning to be safe because I didn’t know?
Hadley, I've never had a dud like that explode seconds after the initial primer strike, but I believe it can/has happened. Think of it this way. Primers ignite due to pressure, not heat. Powders ignite due to heat. So, if the firing pin strike doesn't ignite the primer, it can't eventually warm up and ignite the powder. However, I'm thinking perhaps the primer smolders or heats sufficiently for the closest powder grains to smolder and eventually ignite. Results: a hang fire. I've often cycled rounds out of battery after a failed ignition with no issues, but that doesn't mean someone once had a partially extracted cartridge go off. Anyone care to chime in?
The marrow is quite delicious and really comes alive if you split and roast them first. It is actually more delicate than beef marrow so I find cooking it down by at least half volume and as rich as 1/4 volume if you start by just covering with water and stewing covered at a low boil for as much as two hours.

Boat tail bullets. My only problem with bt bullets was in my TC Contender 7mm TCU with a Nosler 120 boattail. 3 powders and a few charge weights each cured me of using lighter bt bullets in it. It shoots 120 Vmax flat base ok and 130 Sierra SSP great. Tested the chamber attempting to find rifling with the 130 SSPs. The bullet is too short. Apparently this mid/late 1980s TC brand 10” barrel is designed for longer/heavier bullets and has a lot of free bore. The Hornady 139gr also shoots very accurately. Enjoyed this episode, keep up the good work!!!

Hi Ron, love your videos and knowledge. I was wondering what you may think/know of regressive reloading. I heard that some shooters are simply popping out and replacing old primers of cleaned cases luring in powder and pressing in new projectiles without reshaping or resizing cartridges to save time and money one reloaded cases.
Salty, the only way that would work, to my knowledge, is with extremely low-pressure loads that don't stress/stretch the case. And the bullets would likely not fit snugly enough. An old reloading technique for making practice rounds for revolver shooters was to deprime, reprime, and seat a plastic bullet. Primer alone drives out the plastic slug. Normally cartridges need to develope sufficient pressure to expand the brass neck or mouth (at least) sufficiently to seal gases from coming back into the chamber. Usually the rest of the case down to the head/webbing stretches to fill the chamber tightly, too. In a micro second they shrink enough for easy extraction, so you can often get by neck sizing only. This gives a tight fit with fired brass in chamber, but usually means the same rifle, same chamber. You've roughly custom sized the brass to your rifle's chamber. But you still need to size the neck back down to grip the bullet. When I build low-power, low-recoil plinking/small game loads for my 30-06, etc., I still need to neck resize. Necks are usually quite carbon fouled after firing, too.
Over a Lab Radar, I get 2800 fps from the 180gr Accubond in my 338-06 and the same from the 200gr Accubond in my 338-06AI. The standard took my biggest whitetail in MO and a nice 6x6 NM bull elk. Both are much lighter and easier to carry than my 338WM, but I still prefer the magnum when travelling to Alaska.
There has been a lot of powder company's that have done great at making temperature stable powders
Jamie from Australia. I think ron didn’t understand what you meant by twist rate affecting velocity. I don’t know myself if a higher twist rate slows down your bullets. But I’m sure you might be able to find out. Im sure it’s explained in a video somewhere. Now curious myself. I’m going to look too.
interesting. For things like that I feel like and I’d bet that there’s some sort of equivalency equation maths one could perform to find out. Not a mathematician or physicist of any sort but just thinking of old algebra and finance equations I learned in high school and college. Hypothetically, like, velocity(x)=twist rate(y). and then it varies in between. Again totally spitballin’ on that one, just a guess. A great idea to find out!
Adam, it makes sense that the added friction of a faster rifling twist would increase resistance and raise pressures. You could also say fast twist would slow a bullet. But I'm thinking one creates loads to safe pressure limits regardless, in which case one gets his highest safe velocity with that combination. I haven't seen any handloading manuals recommending loading down for fast twist barrels.
@@RonSpomerOutdoors-Podcast ok. Great point Ron. Thanks for the info. I was thinking along the the line of having two identical rifles firing the exact same load. Only one barrel has a fast twist and the other a slower twist. I just think comparisons with everything else being equal that the fast twist might have a little lower velocity at the muzzle. I like to learn anything i can. That’s why i like your show so much. A lot of good useful information that hunters and shooters should love.
Your explanation of the cold air trajectory seems in line. But, having spent all summer in the Tennessee climate working up loads for elk season in Colorado, I have found that elevation and humidity have a bigger impact on bullet trajectory than temperature. Your thoughts?
Elevation is air density: in meters, sea level is (mmHg) 760 at 2400 it's 564.
While temperatures definitely affect air density, the effect isn't as great as the elevation change.
Elevation and humidity work on trajectory the same as cold does -- they modify air density. Elevation means less air pressure, but it usually also means cooler temps, so the two offset to a degree. Humidity makes the air less dense, too, which seems odd, but is proven. Fortunately, none of these factors is significant until beyond 300 yards for big game hunting. Ballistic calculators can figure them out and give you corrections. They are needed for extreme range target shooting.
Great content makes me feel like I’m sitting at hunting camp listening to one of my uncles
Something to think about in cold weather is the impact of cold on barrel steel. Cold causes steel to contract thus generating more resistance which impacts velocity. While heat causes steel to expand. This is why 1st cold shots out of a rifle are slower in velocity than a heated up barrel.
Hello from alberta canada 🇨🇦
What's the latest on Trudy stealing your rifles?
If boat tail bullets don't shoot well from a rifle the first thing I would check is the crown of the rifle barrel. Even the slightest imperfection in the crown can cause yaw in a boat tail bullet.
Faster twist rate barrels absolutely restrict how fast you can launch a bullet of a given weight from a barrel. Nobody talks about it much, but the standard twist rates were always a compromise that would stabilize the heaviest (longest) bullets commonly available in a given caliber, while still allowing good velocity from lighter bullets. Also, sometimes a boat-tail bullet is just long enough to not stabilize well in a given barrel, whereas a flat-base bullet of the same weight often will. I've seen it a couple of times with wildcat cartridges built using a barrel previously chambered in a different cartridge.
what does someone like you with that level of knowledge think of that 8.6 blackout in a 1:3 twist barrel? Just curious, I am a total newbie to all this type of stuff.
@@nozrep - The only reason you would go with such a fast twist rate is to stabilize bullets that are very long and heavy for the caliber. I have seen how these bullets are supposed to perform and I find them to be a solution in search of a problem. Many cartridges are coming into existence because they fit the AR-15 platform. For my money, if I wanted an AR shooting .338" bullets, I'd just get an AR-10 in 338 Federal. No absurdly fast twist barrels or gimmicky bullets needed.
@@jasonbroom7147 yes thank you! i like that idea too! haha yes I just saw a Kentucky Ballistics video doing a 300 Win in an ar10 platform and am thinking, want want want want. Haha and also I had seen before a 30-06 in an AR10 somewhere on the videos that was super cool also. Alas… money. So I gotta stick with a .308 or.223 for my “starter” ar as I have only ever shot bolts and levers and shotguns for hunting.
@@nozrep Totally understand. I have way too much money wrapped up in freedom pill launchers.

Hi I enjoy your video there is so much good information . I have a question is the 270 win ammunition still available out there here there is no we're to be fond I m just wondering ?
I've seen it on Big Box store shelves, no problem. Try online orders, too. Always works for me.
I’m in the middle of va and that has always been a caliber that is most of time on the shelf 270win, 30-06, 308, 30-30. My grandfather only ever used a 270 my brother uses his actual gun now my dad use to as well and I take his old 270 out one or two times a year and to be honest I love it iv taken black bear white tales I would take that gun any where in the world and truck my life to it to do the job as long as I do my part love hearing people keep the 270 alive
It's more complicated to order ammo online here in Canada and yeah the 270 win use to be the most popular ammo around here but not right now I could even find a die for reloding for long time finely I got one
@@peterzachariasmartens2756 Oh, Canada. 😵 Simple as any online order in Minnesota.
I could use some help deciding a caliber for white tail hunting I used a friend's 6.5 creedmoor this past year but I'm trying to decide what caliber I want but I don't want to damage to much meat any recommendations and do you think rib meat is worth it on kansas whitetail
"Worth it" for rib meat is up to each individual. I've never bothered with it, but some do. As for KS calibers, there are literally dozens that will suffice. It's tough to beat a 7mm-08, 270 Win., 308 Win, 260 Rem., 6.5 PRC, 6.5 CM, or something similar. I've also had excellent results in KS whitetails with 25-06, 243, 6mm Rem., 22-250 AI, 300 Win Mag., 30-06, 280 AI and many more.
After 3 years of intensive study, I have concluded that the internet opinions cause a significant drop in projectile performance. Anxiety sets in and they just don't have enough lead in their pencil to perform.
I’ve liked the idea of that 6.5 Sherman short mag
Love this video. One of my friends has a 270 Sherman and he really likes it. He tried talking me into doing it with one of my 270s. But to me all the xtra case work isn’t worth it. I’d just shoot a mag round such as my 270 WBY. He really likes playing with 270 cal rifles. He has several 270 WSM rifles and recently barreled one in a 270/ 300 win mag that really woops my loads that where hot for my 270 WBY. What I’d really like to play with next would be a 280 AI. What’s your opinion on the 280 AI or the 270 AI.
I've used the 280 AI since 1991 to take elk, moose, sheep, coyotes, mule deer, whitetails... Fantastic tound hot on the heels of 7mm Rem Mag performance in a 30-06 size case. And now you can get factory ammo. Much more convenient than any wildcat.

The question about temperature reminds me of an exchange in Ice Station Zebra:
Capt. Anders: A bullet goes just as fast up here [the Arctic] as it does down there. [Southeast Asia]
Jones: ot quite. An insignificant difference, perhaps, but I think you'll find the operational characteristics of the M-16 indicate that a bullet will decelerate as much as forty feet per second per second faster in these climate conditions. It's denser air, you know.
I make born broth from mule deer and black bear bones. Both are outstanding.
My 338/06 will shoot as flat as a 6.5 credmor
230 grain @ 2740 bc is .617
Yes, so long as MV and BC are the same, trajectory will be same.
My only problem is with leaving bones out there is if you are in cwd area. Otherwise on public ground it is great debone deer in the field.
I believe the reason the 338-06 is far from .338 win. mag. is that the 338 diameter hasn't gotten big enough to be able to use the faster burning powders that can be used in a 35 caliber. The reason the 35 Whelen can reach such high velocities and energy levels is because it uses powders that aren't used in smaller bore diameters. For that reason the 35 Whelen can come much closer to .338 levels and by using much less powder. The .358 Winchester is another example of this. If the .338-06 is compared to its parent case the 30-06 then the 338 increased the values of its parent by a fair amount.
The other thing that could happen with a 168 grain 7mm if it was a very slow twist rate or if he was using a very long bullet perhaps a monolithic bullet he could just be to long for his rifling. Remember it's the length to diameter that matters.
For the .338-06 and other times you increase bore size the rifle is becoming more powerful. The area that the gas can push against is how the energy is transferred and for a given barrel length you will get more power out of the same volume. It will also provide better performance with a shorter barrel since you have the same amount of gas going into a higher volume bore.
You actually get one more advantage and this could reflect on your cold weather question as well. As the bore size increases the ratio of bore area to surface will drop. That surface area will be sucking heat out of the gas. That is a parasitic loss. Heat and pressure are basically the same and you can really only get your powder to burn and keep producing gas when the pressure is high enough to sustain your burn speed. After that the pressure and heet will drop as the bullet moves down the bore and creates more room for the gas. Any heat lost into the barrel will drop your pressure at a faster rate. Heat transfer happens faster at higher pressure and different alloys have different rates of heat conduction. I have read that the brass case can actually soak up 40% of the energy of the powder column. This transfer is really complex and even the heat treatment of a metal will affect the speed of this transfer but when all of those surfaces are cold it's going to take some amount of increased energy from the glasses. Cold also slows chemical reactions and this is where modern powders are doing a better job of getting a more consistent range for a stable burn rates. It's my understanding this was a bigger problem in slower burning high energy powders. Single base powders that are nitrocellulose based do well across a large range of temperature. Slower powders are used to develop higher velocity. Because they are slower the bullet can begin to move forward and create more volume and allows you to use more powder without excess pressure. To help develop more speed they also design them to have a higher energy content and di this by adding nitroglycerin. This makes them a double base powder. It's the nitroglycerin that has problems at lower temperature and newer formulas are able to mitigate some of the losses. I have read that some of these are actually triple base powders. These used to only be used in cannon and gun rounds for military use use.
For your Canadian hunter if he is really worried there may be advantages to using larger bore cartridges. With the larger bore size they use faster powders already. This is another reason they do better with shorter barrels since there is a trade-off with slower powders where it takes longer to get to peak pressure where you will get faster acceleration making better use if the full barrel length.
Since I am going on about internal ballistics I want to say that one thing that you don't hear as being a downside to faster riflings is that it will increase friction and some energy will be wasted although the amount is small.
I am really seeing internal ballistics as being somewhat overlooked for most shooters and am trying to understand it better. If anyone knows if any good references that I could get my hands on I really want to study this more and have hopes of doing some gun design. I think some really interesting guns could be developed if we could start using gain twist rifling and sabots. This could make medium bore or even large bore rifles really useful since we could get by with nice short barrels but still have fast enough twist speeds to stabilize popular long range calibers. It even gets better if ultra high pressure cartridges become common.
I have found that 22lr doesn't group well in temperatures below negative 20 degrees Fahrenheit. I assume that slower powder combustion is the cause.
Yes, I'd guess inconsistent powder ignition, Andrew.
Oh man I'm so bummed out I thought I really won. 😭 Just kidding I hate scammers.
Cold weather does make the air denser and high altitude make it thinner. .I always thought it was the lower velocity in cold weather more than air density. Be interesting to see someone do the calculations for wind resistance, that is beyond my ability to do.
Does temperature affect ballistic performance? The answer is yes, it does. Does it have a big effect? Not really. According to the QuickLOAD internal ballistics software (which employs a thermodynamic model for simulating the combustion of the powder inside the barrel) nearly all commercial powders exhibit some temperature sensitivity to burn rate and pressure. Typically, one can expect a variation in muzzle velocity of 1-2 ft/sec per degree F of ambient temperature difference, depending on the specific load. In addition, there are published correlations that show how to correct the published G1 ballistic coefficient for temperature, atmospheric pressure, altitude, and humidity deviations from the "standard conditions" that the published BCs are defined at (see, for example, the external ballistics section in the Sierra Reloading Manual, 3rd Edition, which is the one I have). Of all these factors, humidity is probably the one variable that has the least effect on BC, but it's interesting to play around with these models just to see how small these effects are. In my opinion, the biggest uncertainty in long range shooting (beyond 400 yards or so) is the unknown wind variation downrange, and whether you are shooting uphill or downhill, especially for steep angles. Not every hunter carries with them a laser rangefinder that corrects for shooting angle (although maybe they should). The other big factor in long range shooting is cant. You must hold your rifle as nearly perfectly upright and vertical as you can. Any clockwise rotation of your rifle so that the plane formed by the line of sight and bore axis is not vertical will tend to throw your bullet off target. This is not a big factor inside 100 yards, but it could be a big factor beyond 400 yards.
When shooting at a living creature, it's always a good idea to stalk as close as possible to your game to ensure an ethical shot.
Just my opinions...
i have no idea what you are talking about because I am not a long range shooter of any sort. Regardless,
I like your opinions and have learned, just from
that!
I make bone broth out of deer, bear, elk and anything else. Then I crush the bones and put the bone meal in the garden. It's the circle of life.
Suppose years from now your living in space. You have a target set up on the moon. How do you figure your windage?
There may be no air , but there are gravitational fields. No bullet drop though.
I was just wondering?
You'd need to know the gravitational attraction, air density, and compute from there for drop. With minimal or no atmosphere, their could be no wind, so no correction needed there. Without atmosphere, a bullet departing at 3,000 fps would maintain that velocity, so fly a lot farther downrange before gravity pulled it to ground.
Yes very true but you have to remember a buck will have territory about 15 to 20 miles long and it could take him a week to cover it all
Cold air drops chamber/ bore pressure a varied amount as it becomes colder, the pressure drops more. However the cold air itself actually allows for less air resistance and friction on the bullet because it is less dense and USUALLY has far less humidity than warm air does,so the air becomes thinner ever so slightly. So it will not get as much velocity,but what it does get will carry further ,with less drop,however marginal it is or isn't. The longest range hunters ,match shooters and similar , at 1000 yards and beyond ,they will notice the difference. The rest of us, probably won't unless you are in -60 ° f .
That's interesting, Corey. I've never heard that cold air drops chamber pressure. Unless you mean that a cold cartridge filled with temperature sensitive powder (that burns with less heat/intensity when cold) produces less chamber pressure. I think that would be accurate. But there are many powders now that show little change with temperature. That is a fine solution to maintain muzzle velocity. But every scientist, meteorologist, and pilot I've consulted informed me cold air is more dense than warm air, thus drag increases, thus trajectory suffers. You are correct that increased humidity reduces air density slightly, so it can offset the density of colder air slightly. Fire a 150-gr. bullet, B.C. .48, 3,000 fps MV, zeroed for 100 yards, and at 90-degrees F. , 50% humidity, it will drop 45 inches at 500 yards. Keep all parameters the same except change temp. to -20-degrees F., and drop at 500 yards will be 49 inches. This is with out changing the cartridge/powder temperature. All trajectory change is result of different air density. Shoot the same bullet at the same MV with a consistent ambient temperature but change the humidity from 10% to 90% and the drop difference at 500 yards will be just 0.10" -- a tenth of an inch. The bullet shoots a whole 1/10th inch flatter at 90% humidity. At 1,000 yards the difference is about 1.5 inches.
It is more difficult to make a boat tail form with the same precision as a flat base, and that can make BT bullets a wee bit less accurate.
Not sure if cold temperature affects the powder/propellant... but cold air is denser than warm air . Still don't think it would make a difference unless it is at extreme distance. 🤔
Fish and Game cover this "cold case" did some comparison at different temperatures with same gun, and loads... It showed a difference for sure!
Temp absolutely effects powder, that’s why certain powders are explicitly advertised as temperature stable.

What about high altitude?
Altitude, baseline barometric pressure, temperature and humidity all effect air density. Precise ballistics calculators need all that info to predict the bullet drop. Aircraft use the term "density altitude" to describe current conditions compared to the conditions used for the "standard atmosphere".

QUESTION:
Ron, if you were like me and from the midwest and considering deer hunting out west in northern Idaho or Montana where there are very big grizzly's that can kill you, what size of a rifle would you carry that can both kill a deer and as a second choice stop a bear or would you use a pistol, etc? I'm wondering if the .308 or 7mm.08 would work in a pinch? I know Bear hunters typically use huge 45.70's, etc.. 44 mags, etc.. which is fine, but I want to be able to shoot a deer at distance.. ?
Thanks for all you do sir!
God speed.
Tim
I've never wanted to lug around a revolver big enough to stop a griz, so depend on deep penetrating bullets in my deer/elk rifle. A 200-gr. in 308 will penetrate darn well and with griz you need to hit major structural bone and, ideally, central nervous system to stop a charge anyway. This idea that a 500-grain anything to the chest will stop is largely wishful thinking. Sometimes you get lucky, but most times they take a licking and keep on chewing. You. Most of our griz attacks come fast and unannounced. Bear spray really does work, but only if you're upwind of the bear and you can unleash the spray in a few seconds. Handguns are faster for those who've trained and wear them for quick use. I trust to my rifle and teammates. That might be the biggest/best defense. A partner to back you up. Especially when field dressing and packing out meat. A good all-round rifle with reach and bear punch is the 338 Win Mag. 338-06 is probably just as good on the bear, not quite the reach for long range deer. 300 mags also good. A 220-gr. or bigger should suffice.
🤠 Ron, I would have to disagree with you on what you told Nick of Minnesota! That 140 grain bullet, out of the 7mm Remington Magnum is moving 3,300 to 3,350 ft/s! In My Experience, With My Big Magnums Operating At Higher Velocities, Flat Base Bullets Stabalize Better and Shoot More Accurately Than Boattail Bullets! FACT, Not Fiction! 🕵️♂️
That’s your old slow twist rates, you have to have the twist rate for the longer bullet.
🕵️♂️ But a 140 grain bullet IS NOT a Long Bullet! 🤷♂️
😳 Plus, You Also "Incorrectly Assumed" What Twist Rates Some Of My Custom Rifles Were Using! 🤣
You are half correct the flat bullets stabilize faster for the first 3 hundred yards then after that the boat tails take over! If you watch Desert Dogs UA-cam chanel he goes over the full reason why! For most hunting a boat tail is not needed. Bullet construction is more important especially for big game like elk and bears! In my short 60+ years of hunting reloading and collecting rifles I have found this to be true!
🤠 I have 45 years of Hunting Experience under my Belt and am also an Engineer! When I am talking about "Big Magnums", Which The 7mm Remington Magnum is NOT, the same laws of physics still apply - but at much different (further) distances! You are correct in stating that the boatail bullets will stabalize further down range! But, we Don't Know exactly what range the gentleman mentioned was shooting at for his game animals, Nor do we Know the Range (Distance) at which he was sighting in at! So, we cannot Make Any "Definitive Assumptions" (Engineers Don't Make Assumptions, but Gather The Facts First) About his Statements! But, For Most People, They Aren't Shooting Much Past 300 yards for their average kill, especially in Minnesota! Thus (I do believe), based upon that information that we do have, that the gentleman that came into the gun store was telling the Truth! 🤷♂️
They, the scammers, are on almost every channel. Almost always have blatant misspellings: clam your prize; massage me for your prize, etc.
I mute them and report them.
Don't think I would want bone broth from CWD deer. I shoot 150 grain nosler interbond long range out of my 7 mag all day and get excellent groups
The smaller buck breeds more doe than the big one do
I think anyone objecting to leaving bones and other non useful game parts in the wilderness would be really shocked to see all the salmon bodies in a river.
White Tail deer fat is not very palatable. Same with it’s marrow. Mule deer is equally sour. That’s why we use pork fat when making our sausage.
Cold Air Kills Bullet Performance? - Season 2: Episode 89
Extreme cold temperature (not air) does not affect "bullet" performance but it does affect "cartridge" or "powder" performance by lowering the pressure of the cartridge. Velocity and energy will be decreased. Conversely hot temperature will raise cartridge pressure. You can say that bullet performance is affected by cartridge performance, but not the bullet itself. Its not the air but the temperature that affects cartridge pressure that in turn affects the bullet. If anything cold "air" is often drier and less dense so "bullet" performance should be better.
I would recommend your doing more research on this. Cold air is more dense than hot air. In denser air the bullet experiences more friction and slows down faster, thus dropping faster. From my 40 years flying in the Navy and at the Airlines hot air is thiner thus we always had to get to a faster airspeed before the thin air would provide enough lift to takeoff.
@@couespursuit7350 Notice I said drier air. Dense air is laden with moisture. You are right I had it backwards. I stand corrected.
@@rbm6184 Again I go back to my flying career and takeoff calculations where density altitude is a concern. Humidity affects air density less than atmospheric pressure and temperature. The affect of more humidity is to make the air less dense. High pressure and low temperature make for denser air.
@@couespursuit7350 Yeah you are right on air density and moisture. I just had it backwards. But powder and the pressure it generates is for sure influenced by temperature and that does affect bullets. You will get a drop in bullet impacts in cold temps and maybe a rise in bullet impacts in hot temps.
Cold air is more dense, but moist air is more dense than dry air at the same temperature. Hot air is less dense.
That about cold air and hot air is true I mean if you don't believe it why do they blow hot air in a balloon instead of cold air hence hot air Ballon
I got a call the other day told me my extended warranty was about to expire, I told him I wasn't interested he said how about a free rifle from Ron Spoomer? I said sure, so he transferred me to your people, how come, they all sound like they are from India?🤣💦💦💦
IF YOU GET AN EMAIL FROM ME ABOUT CANNED MEAT, DON'T OPEN IT, IT'S SPAM.
Love it!
On a average a buck spend. 24 hours with that doe so ,maybe 3 a week
Deer/Elk marrow is delicious. Not waxy.
your rite, the only thing wasted on a game animal is what the hunter takes out of the ecosystem from wich it came.
Which is why we can consider humans selfish for locking themselves in caskets and concrete boxes upon their demise.
Cold weather..its not ballistic instability due to hot projectiles and cold air, it's as you said it's air density. Carried to extreme barometric pressure also has an effect.
Air density is part of the routine corrections for artillery.
Something I haven't heard about in years is over pressure in extreme cold. I know it has happened, but personally, I always considered it an issue with the difference in temperature related expansion/contraction rates between dissimilar materials, leaving a bore to tight for the cartridge.
I've never heard that cold barrels contract enough to decrease diameter and subsequenlty raise chamber/barrel pressures.
If someone says you won something and you have not actually entered anything then believe me you have NOT won squat. I am amazed as to how many people seem to be falling for these scams wither on the phone, mail or social media.
Who actually fall for the scams???🤣
You should show what it would really look like to give someone a gun. I myself would be willing to receive such a gift from you for the sake of protecting your viewers. You could make a video of it so people could see what it would really look like and that anything different pops up it is a scam. Hint- Voooooooodooooooooo
I thought I won. Texted the number and my phone is blowing up
oof. how old are you? are you one of those senior citizens who does not immediately assume all that stuff is internet scams and such and thus is vulnerable to scam and hacks? Sorry that happened to you. But I am sure lessoned learned. May I encourage you to be vehemently skeptical within yourself about anything like that. Test it off of a land line phone if you just really really really think you won an actual thing. Those hackers can steal bank stuff off of your phone just from what you did if they are savvy enough hackers.
