Arrow Weight Testing for Hunting - High Momentum
Вставка
- Опубліковано 15 лип 2019
- I tested a bunch of different arrow weights through a chronograph with my bow to see how the kinetic energy and momentum varied with increasing arrow weights. Interestingly, both energy and momentum continued to increase through the heaviest arrow I had. There was no "sweet spot". I could have kept going heavier and kept increasing both momentum and energy. The only downside to a heavier arrow is trajectory, and that is something that has to be evaluated based on your setup, intended game, and intended shot distance.

This is an awesome project. I always appreciate when people start talking numbers and making sense.
Fantastic job of putting this together and presenting it in a manner that makes sense. I’ve looked all over for information like this and not found it so thank you!!
Excellent!
This is one of the most comprehensive & straight to the point test data I’ve seen. On this subject.
Congratulations! Thanks for sharing.
Well done!
Good to see actual data supporting a hypothesis instead of these know-it-all’s telling everyone what they think is the best.
Great video and very well presented! The problem is that so many archers get seduced by speed that they forget there is more to the equation. As you pointed out the only real drawback to a ultra heavy arrow is trajectory. Today we have so many great sights and equipment to compensate for increased trajectory, it is easy to overcome this drawback. I feel the gains you get from a heavier arrow and broad head combination such as penetration, increased momentum, quieter bow, and less wear and tear on your limbs and bow arm are well worth it. Again great job of presenting the data it's refreshing to see facts and science instead of opinions! Thanks Garret!
This is really nice analysis. When I first started archery, I noticed the much more expensive bows were much heavier than the entry-level one I bought. I am still perfectly happy with that bow and have no need right now to upgrade, but if I discover some of these issues, I know what to change and why. There shouldn't be anything magical about trajectories, and when presented in this way, the mystery is dispelled. Thanks!
Very thoughtful and informative video. Thank you for the great content.
Shocked by the momentum part, but glad to see it. Thanks for sharing this.
Very good presentation Garret. Nice work!
Most informational video IV seen in a long time great job
I have been researching this topic for months, this is the best and most accurate video I have found. TradLab
Thanks Cody! I've been closely following your testing with the Push crew. Great stuff. 👍
Excellent video, the results speak for itself. Thank you for doing so much of the homework.
Excellent video, great information. Thanks for posting.
Great video, with heaps of info. Well presented.👍🏻
Great video man. You went above and beyond with The analysis on this one. The facts are the facts. Heavier is better with bow hunting. But there is a happy medium to get the job done. I shoot a Matthews switchback XT at 74 pounds 30 inch draw. 474 Grain total arrow weight. Bone crushing pass though city every time.
Super well said and all the aspects are covered
Having shot both high end compounds & custom recurves I can say that the way an animal reacts @ the time of the shot (especially a mature 1) u can't go wrong with having an efficient setup that is quiet as u can get it.
Excellent video. Thank you for all you do.
The detail in your videos are incredible. Your humble honest assessment is refreshing. Great video. The trajectory become the largest hurdle for us. The pin gap is so great in the heavier arrows that the error for the shot placement is much higher at close ranges. There was a foot distance between my ordinary arrow and the heavy build at 30 yards (I am shooting a very fast bow, so speed and kinetic energy shouldn't be an issue). That means that if you use multiple pins the gap will be significant if you space them in 10 yard increments. Moreover if you are using a single pin you will need to range for accuracy past 20 yards. Long distance shots are really more complicated when you are shooting a heavier arrow. With field points at ranges from 20-30 yards there was almost no difference in penetration in our tests. We tested arrows with a total weight of 375gn, 475gn, and just over 500gn. Lastly penetration is also dependent on arrow tuning, arrows that enter the animal/target with no oscillation or angle penetrate significantly better. Last last thing...Not sure how you test it but heavier arrows are on your string longer so shooter error could be an issue. As with brace height, the less time the arrow is on the string the more "forgiving" the bow is. A heavier arrow is taking more time to push out of the bow and stands to reason will be on the string longer thus giving more opportunity for torquing (not twerking that's a different issue), or other form errors.
12" drop in POI with roughly 100 grains? What bow were you testing with?
Excellent video well done and we’ll said! Best of luck this fall
Great Info, the Ranch Fairy would be proud...
i guess Im kinda randomly asking but does anybody know of a good site to watch newly released tv shows online ?
@Harvey Mason I use FlixZone. Just google for it :)
Fortunately, I’m not into fairys.
I have been arguing with people for while that KE doesn't matter as much when it comes to penetration, thank you for this! Also much of this falls in line with what @ranchfairy has been saying about heavy arrows.
Fairys aren’t real.
@@talisikid1618 they are if you believe.
IMHO- KE is a more of a marketing gimmick. 75 ftl-bs looks allot better on a page in a magazine than .6sl-ft. Remember KE has velocity squared. In most rifles it's fine. But, remember, pistols & bows are slow. Also, RF says he's started seeing a big jump in penetration, at the ranch, with arrows at 500-550gr. Which isn't too hard to do. Old fashion XX75 aluminum with a 300 spline is 13.3 gpi. x 28" arrow = 372.4 grains total, then you add insert, point, vanes & a knock. Easily, 500+
as usual, great video with great info
Great video. Been a fan of heavy arrows for awhile now.
Great video, love my EZV!
Nice video young man. You spent some time working on it. Very well done.
This is a sure fire way to find the weak link in your bow lol very helpful info for sure.
Excellent info, well presented.
There are many videos like this but yours seemed the most informative. Perhaps you could evaluate what is the minimum speed needed to hit a quick reacting jumpy animal, and from there determine ideal weights, from common hunting distances.
No bow shoots fast enough to beat an alert Whitetail. Some studies show you'd have to shoot about 6-900 fps to beat them. Now it may increase your margin some, but a heavy arrow is generally much quieter. This is good. Always far more important than speed, within reason. Now I don't at all believe anyone needs a 650 grain arrow for killing deer. But one learns how to tune an arrow to a bow on that journey so go for it. And then settle back towards the middle like truly experienced hunter do. Perfect arrow flight and placement beat everything else. Period.
Your videos are the best, good stuff
Absolutely brilliant!
I have watched this video twice now since you uploaded it. Maybe 3 times, but any way. Awesome info and everything showing exactly what you are discussing. I believe you are correct with thinking you will reach a point where the heavier arrow will pass the slower arrow. I also believe this idea definitely translates to archers shooting at critters out at further distances. If you shoot at something out past 50 yards, the heavier arrow will have more impact power than the lighter arrow and could actually hit at the exact same time as the lighter arrow. Which puts you back at the question of what arrow is best at any distance? I believe the heavier arrow will out perform the lighter arrow no matter the distance. There is exceptions only when shooting at smaller critters that are a bit quicker on movements, I.e. squirrels, turkeys, and so on. When shooting at these you will be at closer ranges anyway and also won't need the same hitting power either. This should be the only time that speed will trump hitting power. At the end of the day you have to consider for the sake of the intended prey what will guarantee the quickest and most ethical take down of that animal. This means, what will allow the quickest recovery due to the animal dieing quickly from a good penetrating shot. Hope someday you or someone can get the chronograph numbers at distance so everyone can see how the weight translates to speed down range. The ranch fairy UA-cam channel has been testing penetration and affects of weight for quite a while with great results. Again, awesome video and food for thought for all archery hunters. Keep up the good work. 👍
Love the video and the data!
Great stuff man.
Funny I should watch this right after watching a penetration test of low vs. high FOC. That was the only consideration focused on, and it was rather eye opening. It also explained why I’m a lot more prone to shoot through targets now, even though my arrows are fairly slow and I’m only shooting 60#. While I don’t think most whitetail hunters need 550g+ arrows, I highly recommend ditching the 100 g heads, leaving off the wraps and heavy fletching, and getting the weight up front where it belongs. Inserts are great for adding weight up front, but a heavier broadhead should translate to a stronger broadhead. Good video.
Great Video! Thanks for the info!!
I hunt with a 556 grain Easton axis 6mm and 2 of the deer I shot last year were through 1 front shoulder. I got a clean pass through and neither went further than 50 yards.
Great information. Grew up hunting whitetails in the northeast, moved out to CO and now hunting elk and mulies. Back east, I want the arrow at it's target as quick as possible. I've had and watched whitetails jump the string and duck an arrow under 30 yards. Had one duck my arrow at 26 yards shooting a Mathews Switchback at 65 lbs. Now, out west... I want the heaviest arrow possible that I shoot well. Elk/mulies I want as much energy as possible to put two holes in it, as well as hit my mark at longer distances if I need to make a follow up shot.
Studies show you'd have to shoot something like 600-900 fps to beat a deer at 20 yards. Shoot a super quiet set up for best chance. A fast bow might get an arrow in one... somewhere..as it ducks and spins. Seen guys hit em on the opposite side shooting a fairly fast set up. Can't beat em
I was shooting around 450 to 475.. I just made a jump with a new arrow and a new insert from ethics. I'm now in the 520 to 550 range. My bow seems to really like it. I'm planning on hunting pa black bear with it and of course white tail. I made the switch to a single bevel broadhead. I can't wait until deer season lol
Mikey Woomer Jr same! What velocity??
@@twobbles10 fast and hard lol. Super smoth. I'm shooting them outta my redwrx 70 lbs 28 draw. Flyin man
As soon as you presented the graph It confirmed what I expected. That velocity falls of slower as you crank up the weight. There is a lower range where the velocity wont fall off more than a few percent, for large increases in arrow weight. Causing momentum to continue to rise until some very absurd upper level in weight (2000gr?).
Which means a #35 basic recurve bow could theoretically use 1000gr arrows to take an elk inside of a close distance (due to trajectory, and/or just the time in flight leading to a miss beyond 25-30yd).
My new theory is start with the bone penetration threshold of 650gr. Then predetermine the distance you will ever take a hunting shot. Multiply that distance (in feet) times two.
This gives you the feet per second (lower limit) that gets the arrow to the target within 1/2-second. I.e. the 30yd shot is 90 feet and that means you want 180fps to get there in half a second.
180fps is average for a moderate arrow weight of maybe 10 grains per pound. So a #35 longbow shooting. 950gr arrrow might only shoot 118fps, therefore your hunting distance is going to be limited to about 59 feet, or 19.5 yards.
But that #35 bow can still take a deer and probably an elk also, because the Momentum of 118fps and 950+ grains is still more than adequate, and even superior to somebody shooting a 400gr arrow at 250fps. (0.497mom for the slower arrow vs 0.444 for the fast arrow. With 0.50 being adequate for Elk sized game).
Very nicely done! Thank you!
I was searching for DAYS to find such an analysis, because I plan to do it for my 200lbs-crossbow. All I see in many many videos and forums is a lot jibber jabber but only few numbers and absolutly no charts.
C'mon. An engineer cant even think without charts :D
Great video. Personally, for deer hunting I'd run the heaviest arrow I can run and get the arrow to the deer in 0.5 seconds or less. For my old PSE Thunderbolt... did I say old... That's a 420 grain arrow at 252 ft/sec, initially. That gets me out to 40 yards max where the arrow gets to the deer about 0.4 seconds after the sound, and that's pushing it. You presented a very good take on the age old argument, but the units for momentum are slug-ft/s. Slugs is just mass.
I shoot a Black Widow recurve 43@ 29”. My arrows are Goldtip XT hunter 500 spine 150g Magnus stinger and 100g brass inserts. Total arrow weight is 525g shooting around 160fps. I limit my shot to 15yds or so. Shot 2 deer so far with it and blew straight through both of them. My compound is 62# and I shoot XX78 2315 with 200g in front. Total arrow weight 590g. Shooting about 230fps. No problem shooting through a deer at any angle.
How does that 500 spine arrow handle that much weight? Seems like it would blow apart first shot. No problems with shaft cracking or anything?
Congrats on the two pass-throughs.
I tried 400’s but they were stiff, the 500’s bare shaft tuned perfect.
@@zacharyadams6277 only 43 pounds so it's in the range. Obviously works I guess.
great information very well done!!!
He rolled that second bear😂
Thanks I was feeling bad about my 221 FPS 606 grain arrow but now Im happy with my build!
Is that a compound orvrecurve speed?
@@keithtomczyk4730 compound, I have a short draw length as is
It'll certainly kill! If you can live with the trajectory. What is your main hunt? Western spot n stalk and stuff or mainly whitetails from a stand? For Whitetail, and generally 40 yards or much less...I'd not mind that set up at all. Millions of animals have died from much lesser set ups. Placement , placement, placement.
@@montuckyman4982 I hunt whitetails and hogs in the South. Going with a 525 build this year for the trajectory.
Looks like some good testing and interesting data! Im wondering if you increased the weight in equal amounts and where it was added?
Increased tip weight until the spine would be weak, then increased arrow mass and stiffness and started working back up through the field points again. The mass is the only thing that matters for this test, not the FOC. If you shot a really weak arrow spine it might show lower numbers due to energy loss out of the bow.
My standard whitetail/bear arrow is a gold tip pierce platinum 300 spine, 500-600 grain total arrow weight. I run ethics archery adjustable insert/outsert systems and 125 grain magnus black hornet, ser razor, or buzzcut broadheads. I alway I mean always get a pass through out to 40 yards which is my maximum kill distance to date. I practice out to 60 but never had to shoot that far yet. FOC is between 18%-20%, with a lighted nock and 5 inch wrap. More animals are lost every season because of light fast set ups with flimsy ass mechanical broadheads. I’d rather my target hit by a freight train that breaks through everything in its path rather than a piece of straw traveling the speed of light that just bounces off. Good video, hope it gets more hunters on the heavy, high FOC, fixed head bandwagon. Their freezers and stomachs will thank them.
Sounds like an awesome setup!
DIY Sportsman I wish I was doing this my whole life. Makes the arrows borderline indestructible. For whitetail or multi species hunters targeting animals bigger than a turkey it’s a no brainer.
Sir you are scary smart!! Congratulations to you and your beautiful new bride!!
Fantastic video. Nice to see more and more guys moving in the heavy arrow direction.
Hi mate . have you looked at different bows and seen if one reacts differently/better
momentum is an excellent measurement.
Awesome video: ? For u.. I know they always talk about F.O.C being between 10-15% for a hunting set up.. as u moved up the weight of each arrow did the FOC stay consistent or do u think it matters?
FOC was all over the place for these setups. It doesn't have an impact on velocity out of the bow.
Great vid
You just had to release this while I’m at work and can’t watch huh!
Very informative!
So Garrett, what's your total arrow weight for whitetails this year? Can you elaborate on the insert and tip weights, also? FOC?
Great video...one thing I have been thinking about and haven't really seen much about is whether or not there is a difference with lets say a 70lb Elite Synergy bow (known to be a bit slower of a bow, but easier and smoother draw cycle) and lets just say a 60-65lb Hoyt Defiant Turbo (known to be a faster bow, but more of a radical draw cycle). With those two setups shooting around the same speed and with using the same grain arrow...would there be much of a difference? Or would it basically just be preference whether you liked the smoother feel from the elite but have to pull 70lbs to get the same amount of stats as a 65lb Hoyt turbo?
I think my eyes are becoming cross-eyed as I'm typing this...
If they are truly the same speed at the same arrow weight, there likely wouldnt be much difference, but it's tough to say which would be faster without actually shooting the arrows or at a minimum using software to estimate. Holding weight at full draw would be different if let-off percentages are equal. Sometimes target shooters will choose cam style based on a combination of arrow speed and holding weight to choose either one of those types of setups to fit their needs.
Can you talk about that DIY quiver I saw in the JX3 video? Comments were disabled so couldn't ask there. thanks!
It's a DIY version of a Quivalizer. It saves some weight and the need for a stabilizer or side bar by putting your arrows out in front and to your bow hand side of the riser. The downside is that it's more challenging to maneuver or carry on your back when walking through the woods. They are more popular out west.
A little off subject but what bow vise is that and where did you get it? Great video btw. Thanks
It's just a Harbor Freight adjustable vise and little HME tree stand bow holder clamped inside.
Go heavy my friend.
I just saw a test where some guys did penetration testing in unused block target with 400gr arrow vs 600gr arrow, looking at equal KE and equal momentum, and their result was that equal KE had similar penetration but equal momentum, the lighter arrow out-penetrated. Their conclusion was that with older bows, the extra penetration is really due to increased KE due to increased efficiency, and that with the brand new bow they were shooting, it's so efficient at 400gr that it would no longer give the efficiency boost for heavier arrows. I'm curious if you know of anybod that's done the type of testing in this video with a 2021 model. What bow did you do this testing with? I checked the gear list but it's been updated since this was made.
I'd be really interested in seeing where, if at all, all 3 data points intersect, or at least triangulate. Would be interesting to then see if the point in that intersection/triangulation results in good bareshaft on a bow tuned to spec.
My initial guess would be no. Because none of those 3 things depend directly on things like static arrow spine or length, or bow tune, which can all have a major impact on bareshaft flight. In other words, Ibelieve you can build both light and heavy setups for a given bow with great arrow flight, by making sure to keep things like the dynamic spine adjusted appropriately for each setup.
Well done as always. Like we say at work: "Let the data lead the way." I wonder, that if all of these numbers could put a deer down, then trajectory, or having the site pins as close as possible for a 20 thru 40 yard shot, may be favorable, as you had mentioned. If trajectory is increased then there may be more misses through that range, but would improve with practice, as indicated.
Yes, and that's why guys shooting high energy bows have more margin of error. They've got enough momentum even with light arrows that often they might still be ok in a less than ideal shot and can use that advantage of closer pin gaps. With lower energy bows it's more of a tradeoff. Closer pin gaps makes it easier to hit their spot, but has a less ideal outcome in a poor shot. Versus a heavier arrow might gives better outcome on the animal but harder to hit the spot. On my wife's bow I have her set up with a relatively heavy arrow and big pin gaps. But she's also accepting shot distance as a limitation, much like I do with my longbow.
@@DIYSportsman Makes sense. Along this vein, I've wondered lately if crossbows in general aren't better for the animal(s): less window for possible errors, putting the animal down quickly, ease of use and practice, etc. Would have to be balanced by the challenge of other equipment, etc.
@@jeffm.1656 Of course their better. My rifles even better. But efficacy must be limited to allow for hunting opportunity. Otherwise , hunts become super limited. Already are limiting seasons with all the cross guns and 100 yard slayers with compounds out there😁. People are getting too effective in some hunts and seasons. Just facts biologists have to balance.
Its Archery, it's supposed to be really hard. 👍
What are the formulas you used to calculate the kinetic energy and momentum?
Thanks for sharing this. What an interesting study on multiple arrow weight setups. Still blows my mind that people can build an 1100 grain arrow 🏹. My current arrow set up is a 11.25 gpi arrow vs the 9.3 gpi at a 29 inch draw. That's a 58 grain difference then add the 45 grain outsert for a 103 grain difference. But I still ended up using a 100 grain fixed blade broadhead like a Magnus Stinger Buzzcut or G5 Montec CS. I wanted to try a 125 or 150 grain broadhead but Cabela's doesn't carry them and internet sites were out of stock.
So putting a broadhead that's heavy enough to reach double what my setup is sounds expensive and hard to find. I know that they make 300-700 grain monster broadheads for deadly game.
I only pull 60 lbs at 29 inches on my old PSE from 2006, and my current arrow weight is in that 510-530 range. I am finally getting them to fly well and similar to my field points.
Forgot to mention that my arrows are the Carbon Express Mayhem SDS 350 spine.
Have fun with it bit don't get sucked too far into the mega heavy thing. 500 grain arrow with perfect flight for any modern 60-70# compound will kill anything in north America. With a good shot. And some speed makes a good shot easier to make...gotta balance it with what your goals are. Some thought for ya.
@@montuckyman4982 exactly I don’t plan on going much heavier if at all. Thank you for your input. I thought about upping the insert or point weight a little bit but that is it.
One advantage you have is speed. With the lighter arrow dr. Grant on growingdeertv did a video on this. Dear reacting to the shot how far they can drop at different ranges. I like staying around the 440 grain range 70 pounds 28-inch draw and I'm shooting about 275fps.
Great scientific data. thank you. Have you done test for arrow length for those data?
For that specific test, arrow length won't matter. It's all just based on weight of the arrow coming out of the bow. Where it does come into play is your dynamic spine which can affect your broadhead accuracy. At really long range it can also play an impact on wind drift due to the change in surface area.
@@DIYSportsman Thank you very much
So going from say 400 mass to a 500 or 600 mass arrow. What is the difference in time of release to arrow hitting the target at 20 to 30 yards for example? How does this translate into say 100th of second time loss? I here so many folks say I don't want to shoot that arrow because the animal may move but all animals move and will that loss of time effect how far they move significantly
My arrows are 455 grain and shooting 265 FPS. Great trajectory and penetration on Whitetail. I’m considering going to 475 to see how it shoots. You are correct on the theory of a heavier arrow going faster at range than a lighter one. Look at a ballistics chart for a 30-06 150 grain vs a 180 grain. At around 200 yards the 180 carries more velocity and way more ft. pounds of energy. The same applies to arrows.
Great content! ;)
Great job, I appreciate all the data. There is a bit of bias when it comes to what an individual prefers to shoot in the light vs heavy arrow setup. Science done incorrectly is a biased opinion that leads to errors. On the extreme ends of the scale there are deficiencies. My feelings are that there is a sweet spot for a weight to speed ratio. Another factor to consider is an animals reaction time. Reference Cameron's Hanes 700gr arrow shot at fallow deer. They jumped the string evertime at 240ft/sec. Another major issue is trajectory I know from hunting and 3d shooting one may only have a small gap between foliage or branches to shoot through. Arrow drop is another concern a flatter trajectory is obviously an advantage at unknown distances, which if you hunt that is problem. The animal may move after you ranged it. Just a few yards could be a foot drop depending on what your setup is at a specific distance. Plus a lighter arrow is known to be more forgiving. There are reasons for why people prefer lighter arrows for competition. For compound arrows used for hunting the general consensus for many years has been an arrow weight of 420gr to 490gr at a draw lenght of 28" or greater at a draw. weight of 60lbs or greater. I've had pass through on 5 elk with a 450ish grain arrow with a speeds of around 270ft/sec. Just an opinion
Yes I do agree, getting the data is one thing while recommendations based on it are another, and time of flight as well as trajectory are both important. Right now I've grown to like around 280fps on my compound and closer to 200 on traditional. Not blazing fast but also not lobbing logs. A happy medium.
what is your current arrow weight for whitetail deer?
Great info fist person to say anythaing about the drop changing as you go heavy...
Did you have to take out a loan for that Bishop arrow? The stuff they make looks good, but their prices are absolutely ridiculous...and their website is nausea inducing...
So I have a physics question regarding the momentum. So as you may know, the equation for momentum is p=m*v, where p is momentum, m is mass and v is velocity. So based on the equation, increasing the mass would increase the momentum. However, when you increase the mass, you recorded that the FPS initially decreased by 30 FPS. Based on your graph, are you concluding that the increase in mass was greater than the decrease in velocity, which in turn resulted in high momentum?
Yes thats the basic idea. The devreased velocity isn't enough to overpower the increased mass factor, and the new m2v2 is greater than the old m1v1.
One advantage of lighter/faster arrow hunting over a known distance (feeder/bait pile): Makes it harder for the deer to move/jump the string.
Yes and no. Speed of sound is over 1100 fps. They definitely have less time to react, but I also think a deer is generally more likely to jump the string on a 380fps crossbow that sounds like a microwave exploding than the thud of a 160fps arrow from a recurve for example. Aron snyder talked a lot about that in his transition to traditional where he got multiple shot opportunities at many animals due to the bow being so quiet.
The lesser of speed drop from heavier arrow is because 100 grains at 1000 grains is ten percent and 100 grains at 400 grains is 25 percent. I guess my question is did the percent in speed change if you figured out number in percentages equally or was it still less effected as the over all weight increased.
I shoot 60# for whitetail and I have a 28.5" DL. A normal shooting opportunity for me is within 30 yards but could be up to 40 yards. I use 28" long Kill'n Stix Original 400 arrows with 100 grain broadheads. I estimate the total arrow weight to be just over 450 grains. In your opinion is that a good arrow weight for my setup? If not, how would you improve it?
That will be an effective setup. The easiest jump in penetration if you wanted it would be to change the 100 grain head to a cut-on-contact version if you arent already. If you wanted to build a heavier setup, I would get a stiffer spined arrow. Then, if you wanted you could keep your current broadheads but use a heavier insert system, like the Ethics brand or similar (many good options popping up). In addition to or as an alternative to the heavy insert, you could run a heavier broadhead. If you just add weight to the front of your existing arrow, you risk becoming too weak in spine which can cause accuracy and flight issues.
What is your draw length with the stick bow? Speed seems slower then I thought it would be.
29.5" but probably less when this video was made.
Nice presentation. Appreciate your no hype matter of fact style.
So what arrow weight do you hunt deer with? Nice video.
Most of mine have been shot between 420-480. Last year I tried 660. This year I'll likely use my 537gr setup at 250 fps.
The numbers from 30 yards would be a cool experiment...I don't think anyone has done that. I had a feeling you were in engineering from your older videos, this one confirmed it, haha, ME myself. The ballistics vs momentum would probably yeild the sweet spot. Like knowing what's the heaviest arrow that would be under a certain drop at 40 yrds. I'm sure there a calculators for that, but real world testing is better imo
Btw- I saw your diy climbing stick video, that was awesome. I was wondering if you had any recommendations for a budget cnc router setup and a 3d printer? I used to do a lot of cad work, so I have that part down, but I've never actually machined anything.
When I bought my CNC, it was a black friday deal on the Shapeoko 3xl. About $1500, and probably about another 500 for tablet, table, cutters, etc. I haven't looked too closely at 3d printers over the past year. Used to be, if you didnt spend at least $1k youd have really marginal quality and several thousand more to get pro quality prints. But the price to quality ratio keeps improving. I'd bet there are good options under $500 now, I just havent used any specifically to say for sure.
The advantage of a light fast arrow I could see would be reaction time. The faster the arrow the less time the animal has to react to the shot. Whitetail don't need a ton of momentum but jump the string like crazy.
yes & no... I also like and have gone to and believe in a light weight arrow set up, but the reaction time you speak of is caused by the sound of the bow which is and/or can be directly related to shooting light weight arrows. The speed of sound is 1125 fps... so if your bow is too loud, I don't care how fast your bow is; your not making up for the reaction time.
Yeah, you won't beat them with speed. Silent and fast and just heavy enough would be ideal. Again..silent, perfect arrow flight, perfect placement.
Just a guy who's never cared about arrow weight even shooting a RPM360 - To me that 605-650gr arrow looks to be a good middle ground..
Good info.
I’m shooting a 43 pound draw weight with 603 grain arrow with 325 grain front end weight. 600 spine. It’s speed is 131ft/Sec. I think that’s 22.9 GT.lbs of KE. Is that enough to get a pass through on a n average deer with distance 20 yards?
Terminal velocity would be the point when the trajectory would be most consistent, but I don't know how you would obtain that.
Drop it through a chrono.
L Parker from a tower? My aim isn’t that good. 😉I’m not sure how long it would take to reach terminal velocity, but I’m guessing it’s at least a couple hundred feet.
@@justinmailloux549 a building, a dam, whatever. Could just film it and see how far it travels per frame. Not that hard.
If you shrink the KE y-axis, does it look like it starts rolling over at some point? Looks like maybe 550gr?
It might have a localized peak around 600/650, but it also could just be noise in the data. Perhaps with several repeat measurements that graph gets smoother.
to me, this says if you're going to shoot >500 gn arrow, you might as well shoot a 650gn arrow. You still shooting the EZ-V? great video
Yea the biggest thing is just being comfortable with the trajectory. Guys in my obervation who hunt close are generally much more comfortable going a little slower, whereas guys who frequently have opportunities 25-50 like faster, or guys hunting out west.
I have a 32" draw, am having a horrible time finding a arrow with enough backbone. I am shooting a 476grain arrow around 296fps.. any recommendations on a arrow
There are more and more arrows coming out with stiff spine options. Black eagle has a couple 200 and 250 spine options, and 150 in the Rampage, Victory has 250 spine and the 240 spine or 170 spine Grizzlystik. Sirius has 200 and 250 spine. Daysix has 250 spine. I'm probably missing some others.
Plenty of weight and speed to kill anything in North America. But yeah...some 200 spine arrows out there
Have you done a review on the EZ V site?
Yes, here's a link: ua-cam.com/video/nwQh3IRSN8I/v-deo.html
What poundage on your bow and what's the ibo speed rating for the bow ?
70# and 330
Ok cool. That's the same as my bow. I'm trying to get an accurate fps for my hunting arrows sin6i dont have access to a chronograph. I'm at 28 draw length with a 505 gn arrow set up.. looks like a 250 fps for me
I shoot 60 pounds and a 29” draw. I got a 350 spine arrow to bare shaft perfect with a 60 grain insert and a 125 point. My arrow is 9 gpi. Is this heavy enough to shoot a single bevel broadhead for whitetail?
That would be plenty. There are no minimums per-se for choosing a single bevel head design. My wife has gotten pass throughs with 40# at 25" draw with a lighter arrow than what you've described. Key was perfect arrow flight and good shot selection.
Also loVe the sight
Can you provide the FOC of the different setups you tested?
They ranged quite a bit, from maybe low teens to low 20s %. Front of center doesn't impact these measurements specifically. Just arrow mass and the bow firing them.
as long as you can blow through a shoulder blade any extra momentum is kind of a waist at that point considering you are sacrificing speed.
So what setup are you using for whitetail with the compound
Most likely I will be using my modified Grizzlystik setup at 537gr and 250fps. I've been shooting it really well with broadheads and it's a very durable setup.
@@DIYSportsman what is your draw length? 27?
@@Americandream_is_alive 29.5
Very good info. I had to switch this year to a lower poundage bow due to therapy on my shoulders. It is set at 50 Lbs. and the manufacturer says to shoot a 400 arrow. I have never shot a bow at this low of poundage for hunting deer. What do you think would be a good setup to get proper penetration? I will not be shooting over 30 yards. Thanks
400 grains and 50# should be sufficient with good arrow flight and a low cutting force broadhead (would recommend sharp cut on contact, 2 blade). Bumping the arrow weight up to 450 or 500 would give a little better margin of error provided you can still live with the trajectory. My wife's bow is 36# and 24.5" draw. I have her with a stiff 500 grain arrow that she can grow with as she gets stronger. But she is also limiting to shots likely under 25 yards and using a sharp cut on contact head.
Thanks for your feedback. I have some 500 arrows I was using with my other bow before I had to go to lower pull weight that I may try to see how the trajectory is.
