How much does helical slow arrows down??

Ranch Fairy compares light 350 grain vs 550 grain arrows with the same helical configuration out to 50 yards. Even he was surprised.

Good video! The only thing I would say is instead of using all the FPS losses as equal. I think you should calculate percentage of speed lost at distance. So if it starts at 300fps and looses 30fps @ 50y that would be a 10% loss of speed. I think this is an important distinction because if you shoot a heavier arrow at 150fps and only loose 15fps that is still a 10% loss so it’s the same but you could argue that it is only half the loss with your calculation. You still proved out your point but saying that the heavier arrow was affected 1/2 as much seems like manipulating the numbers. Thanks for another great video!

[@stephencarter7495]

I thoroughly enjoy these technical videos, I'm a mechanical engineer who loves archery as much as nerding out on adult arrows.

[@xSPORTSMAN1993x]

500-550 seems to be a really nice sweet spot for speed and ke with high foc. Easy to obtain with regular store bought stuff

[@benji4840]

true, we need lead cored copper inserts! or something. otherwise, the insert gets really long, or you have to buy heads over 200grain and that seems to jump the price a lot.

[@loganzimmerman551]

It works quite well. I've shot through deer legs with my 524gr setup. A 30" 70# draw on a Mathews Traverse puts some power behind it. leaves the bow at 260fps. Victory RIP TKO with a 75 grain insert and a 125 grain head.

[@Bowbender8]

I've moved from 410g to 525 the last couple of years and have been surprised by the step up in penetration. This coming season I hope to be at 600+ and fixed blades. I've been slow to give up on mechs.

[@SpearsUnclaimed]

That’s what my conclusion is coming to as well. I hunt in Alberta and run a 630 gr arrow but thinking I could benefit with a little bit more speed by dropping to 550 and wouldn’t feel too sad about it. Next year!

[@claywright3895]

I agree I'm at 525 and it's a deadly combination!!

[@wiscofun3028]

Your changing two variables, mass and velocity. In order to calculate loss of efficiency your going to have to keep one of those constant. If you're interested the effect of mass upon speed erosion you need to have a constant launch velocity. The 300 grain and the 500 grain both need to have the same velocity at launch to compare the effect of mass on speed erosion. The way your doing it now, you have no idea if the increased mass or slower launch velocity was responsible for the reduced speed erosion.

[@bakters]

They are doing nothing wrong. The idea is to deliver some practicable numbers to actual hunters, not to rewrite a textbook on aerodynamics. The take home message is that if you increase the weight, your arrow might be slightly slower at launch, but it will keep its speed better, and you don't have to worry as much about speed loss due to bigger fletches. With that said, you are correct. Depending on the regime, drag is either proportional to speed or to speed squared, so a slower arrow experiences less drag overall. What does it change, though? Higher sectional density helps, slower launch also helps. Both aspects work in the same direction, as far as speed erosion goes.

[@WM-jy9dz]

your approach would require to change the bow - the point is to gather data for one bow with a fixed draw length and fixed poundage (thus a fixed amount of spring energy stored in the bow) to evaluate the impact of various arrow weights and various fletching configurations (that is what we normal mortals can change) on KE losses.

[@rootjr.3658]

Correct, but practically speaking it doesn't matter much. The majority of bowhunters are shooting bows that will launch an arrow of a given weight at relatively close to the same velocity, and are more likely to drastically change arrow weight than bow draw weight. Therefore, launch force for most people using this information remains the same, mass and velocity are inversely proportional and dependent on one another. However, fundamentally both the increased mass and lower velocity are responsible for the reduced speed erosion. The additional mass increases the the inertia of the arrow, while the reduced velocity also reduces the air resistance. You could do some calculations or testing to find out which has the greater impact on the speed erosion, but it has limited practical use since mass and velocity are so closely tied in this type of system. By this I mean that the limiting factor is the human body. Since most bowhunters are 60-70 lbs. draw weight and 28-30 inch draw lengths, there is not much variation in the correlation between mass and velocity and the trend will hold true.

[@the_sharp_carpenter]

@@rootjr.3658 could get Josh Bowmar in to shoot his 95lb 31" draw bow that shoots a 550 grain arrow over 300fps to check the numbers lol. But like you said there are only a handful of gorillas that use bows to hi t with.

[@phobiarg]

The lighter arrows are losing about 10% of their initial velocity at 50 yards. The heavier arrows are losing about 6.5% of their initial velocity over that same distance.

Don't make a mistake on your shots with those heavy points.. your vanes won't do their job.. takes an hour for the arrow to get to the target.. your pin gap is insanely bad.. and you don't get anything substantially better in penetration and kinetic energy. Kinetic energy = 25LBS = rabbits and squirrels 25-41LBS = deer 42-65LBS = Elk/Bear/Boar/etc. 65+LBS = caped buffalo.. Just based off of your first arrows figures; your kinetic energy for the 337 grain arrow is 69.7lbs at 0 yards and 59lbs at 50 yards.. your kinetic energy for the 537 grain arrow is 71lbs at 0 yards and 65lbs at 50 yards.. You are leading people on the wrong direction in my opinion.

Good work fellas. I shoot aluminum arrows, which are naturally heavier than carbons, and I shoot fixed blade heads with a strong right helical. My old Mathews bows still shoot a relatively heavy arrow around 250fps. I almost always get complete passthroughs. I remember shooting a buck with a steelforce head (cut on contact) overall arrow weight around 520 grains. That arrow sliced through the deer so effortlessly that it stuck in the ground and buried itself into a tree root. The reaction of that deer was rather like nothing, and he actually turned around and smelled the arrow that just went through him. He walked a short 15 steps and piled up!

[@baseballslamer24]

[@mikemcgill3998]

That's a good/ interesting thought. I'd like to see it.

[@jessemorales7791]

I sorta did a test like this when I was measuring the fps my bow was putting out with the arrows I just built that are somewhat adult arrows (553g with a 125 broad head). I checked it and I was shooting 247fps with a field point and then tried with a kudu broadhead It shot 251 fps then preceeded to try others I had such as magnus black hornet(244fps) QAD exodus(245fps) and the annihilator xl (243fps) . I don't know what it was at 50 yards, I used a chronograph.

[@rootjr.3658]

Once the helical gets an arrow spinning (rotational velocity) the drag is going to be reduced, because relatively the airflow is flowing close to parallel to the vane and you are mostly just left with the resistant force of the frontal cross-section perpendicular to the vane's path. As the RPMs go up however, you could go with less vane (AKA less tillering resistance) because you will have the addition of gyroscopic inertia to help with stability. Bullets fired from a rifle rely solely on gyroscopic inertia for stability. Theoretically you could do the same thing with and bare shaft (no vane drag) if you could find a way to impart a lot of spin to the arrow prior to the arrow leaving the bow. However, then the cross-sectional balance of mass could be problematic. An example would be sharpening one side of a broadhead more than the other, you have more mass on one side than the other. This would give similar results when a load of laundry gets stuck to the side of the drier and starts to bounce or your car's tire gets out of balance.

[@Arwndr]

There is limits in spining. If arrow spin too much that start to slow down arrow. And there is a complex movement of arrow in the air: waiving/oscillating from shoot impulse + spining from fins. Depending from oscillating ratio - spining reach maximum possible rate and never go higher. (depends from stiffness/spine of arrow) In that case, if fins have more helical degree than that maximum possible - appears additional drag force. And also when arrow already in that "stable" spining with as you described parallel vane going through the air - there is some small losses of spin through the air drag friction. So helical vanes/fins again add more drag in this moments to become into this "parallel" mode again. So they are not really "parallel", they all the time do a job for small corrections through the air. Same as straight vanes all the time do a friction job because of arrow all the time starts to spin right after shoot. (because of string twist)

[@offthearrowshelf]

this is really fascinating video. I'd be really interested in seeing if the results would be comparable if you were shooting a slower bow, sub 200 fps. I shoot a flatbow 45lb wooden arrows comes out around 172 to 176 feet per second with a 460 grain arrow, 4.5 inch batwing feather (3 fletch) . Thank you

[@WM-jy9dz]

not everyone may be aware of this: feathers cause actually a much higher drag (in order of 30% with these speeds) than plastic vanes (birds need the thrust caused by the drag otherwise they couldn't fly 🦅 ) hence the findings are not a surprise - even a straight feather fletching (no off-set, no helical) will cause a significant drag. That might explain the fact that there was not much difference in the speed erosion of the 3 feather fletching variations.....maybe that is also the reason why they don't put feathers on missiles 😂😂😂....the rocket man will know .....I shoot these VAPs for 3D (350 spine) in a 3-blade / 2" low profile setup with only 1.5 deg off-set configuration, for the hunting arrows I want to try (300 spine) a 3-blade / 2.25" tac vanes with 1.5 deg off-set. They don't need more fletching as the "steering" drag (=losses) at those relative high speeds is just significant higher compared to slower bow-arrow combinations.

[@driftlesshunter9200]

I couldn't see your entire sheet, but I will use a couple numbers that I could see. 300 fps - 269 fps = 31 fps. Now take that a step further to be fair here. 31 fps/300 fps x 100% = 10. 3% loss in arrow speed for that comparison. Another one I could see was 239 fps - 224 fps = 15 fps. Take that a step further. 15 fps/239 fps x 100% = 6.3% loss in arrow speed for that particular arrow. I think the point you wanted to make is still intact, but ..... Using a simple example here - A car going 100 mph slows down to 60 mph. That car lost 40% of its speed (40 mph/100 mph x 100%). A second car going 50 mph slows down to 30 mph. That car also lost 40% of its speed (20 mph/50 mph x 100%). Just make sure you have the right EZ V insert installed in your sight for your set up, & you are good to go!

[@mab0852]

If Rocketman is doing math, you should show the proportional change in KE and Momentum since KE greatly favors speed over mass and really doesn't mean much at archery velocities. Your bow is a fixed KE input for the most part. While heavier arrows make the machine slightly more efficient in translating the KE to the arrow with less loss, it's marginal. You saw that in your last test. Change in momentum is what drives loss of penetration on the target.

[@keithqueen352]

Honest question, why do heavy bullets travel slower and hit harder than light bullets of the same caliber?

[@mab0852]

@keithqueen352 with increased mass they have higher sectional density and as a result a generally higher BC. KE=1/2 m v^2 Since the initial KE is ~fixed in a bullet or a bow and the lighter bullet starts faster at lower mass, but decelerates quicker it's giving up energy at a much higher rate than the heavy bullet. This is grossly oversimplified, but that's the primary reason. My LabRadar gives me speed and KE over distance. You can use insert weights to send a light and heavy arrow from the bow at the same initial KE and see the light one's KE drops faster over distance. I've done it many times just playing around.

[@Njjb122]

This test showed me heavy arrows are really slow i dont think it matters if they lose 50% less speed the pin gap is going to be even bigger at the speed difference between light and heavy it just seems to me like the 425-500 gr arrow with 100-175gr up front with a 3 fletch helical reigns Supreme for all north America game animals...but everyone already knows this

[@mikewest5809]

It's on my bucket list to hang out with you someday. Great video, always fun to watch you have a good time. You had me at, now it's a slug. I don't think any of that is relative unless you start out at the same speed going from light to heavy. So, you would have to drop the poundage on the bow to shoot the light arrow and put it in slug mode as well or bring the poundage up to 90 or 100 or so to make the heavy one fly as fast as the light one. One way or the other or both. Otherwise, it's not a realistic comparison. On top of that when we put the light one in a momentum calculator we come up with 1.8. When we put the heavy one in there we come up with 2.5, a difference of .7 at 50 yards. I get it if you make the heavy arrow go the same speed or even close to the same speed as the light one, then it will definitely hit harder in a way that will show up substantially. The other question about all of it, that baffles me.> What does it really take? I put a 370-grain twizzler through both shoulder scapulas of a Bull Elk at 30 yards with a Magnus Stinger at 242-FPS out of the front of the bow. I don't shoot that slug anymore but I shoot the same weight arrow at 275-FPS. I just put that through the shoulder of a Bull Elk and into the spine and dropped it like a rock at 40 yards. You couldn't even get the Magnus Stinger back out of the spine it was in there so deep. Couldn't even see the back of it. I have been using a 370-grain arrow for around 20 years now and have more kills than I can count with it. I have broken front leg bones, and spines, and punched through scapulas. Hell, I used a 440-grain arrow when I lived in Alaska because they required it to be at least an ounce back then, now they don't have an arrow weight restriction. I put that thing through plenty of Moose out to as far as 50 yards and as close as 12 yards at 260-FPS. Talk about Big Bones, I put that twizzeler through the front leg bone of a Moose and on into the vitals. It cracked the front leg bone from ball joint to Ball joint in a spiral. It was such a cool-looking crack I kept the bone for the longest time. I wish I still had it. I still have a front leg bone from a Deer I cut completely in half right below the ball joint the arrow went clear to the vanes, with a 370-grain arrow at 270-FPS. I know you know, but I think it has more to do with head choice than any one specific choice. A sharp Magnus Stinger will kill and penetrate plenty enough to get the job done, light or heavy. As far as your speed test, the facts are that the pin gaps will be closer on the light arrow every time if it's going faster. I also believe the chance of them beating the arrow is way better with a slow arrow. I haven't had it happen once since I quit shooting slugs. I have had them try.

Does heilicle slow down an arrow? Yes. You spend energy turning the arrow. You do so by adding drag. Its not rocket science. Perhaps it is but it isn't complicated. How much? Depends on how many vanes, degree of heilicle, diameter of the shaft, how long, yada. Short answer yes.

I would love to see you test ethics archery spinning inserts with the same vane combos. If the arrow doesn't need to spin the mass of the broadhead do you get the same losses

[@WM-jy9dz]

if you have to maintain a heavier mass spinning it won't need more energy to overcome the air friction (air friction depends only on surface and speed) plus as the spins for an arrow are actually very moderate numbers (perhaps 1 full turn every 3 to 4 meters) the energy lost for spinning is only a fraction from the overall friction losses caused by the vanes anyway (also straight vanes have a significant drag thus eating KE).

[@GerbenNZ]

Question about the effect of helical slowdown. These are some random thoughts that popped into my head as I imagined the effects shown in your video. Not sure how to word this in an understandable way, but I'll try my best. Helical fletching seems to have more drag because it has a greater profile exposed from a forward view. However! If an arrow spins, the air doesn't flow straight along the shaft. Instead it travels along the arrow at a ratio with a certain length down a shaft and a certain amount along the circumference due to the spinning action of the arrow. I can imagine an arrow spinning at a rate where the helical fletching is actually straight on in the air flow at that time. The initial spin of the arrow is created by the fletching, so I suspect the rate of deceleration of the arrow is super high in the first few feet of flight as the arrow spins up and then the rate of deceleration drops as the fletching's offset starts to match up with the airflow. At that point I suspect the helical fletched arrow's deceleration is similar to that of a straight fletched arrow. A spinning arrow may fly more stable sooner and lose less speed (due to reduced time flying "sideways" as a straight fletched arrow stabilizes). This may compensate for the added loss of speed early on compared to straight fletched arrows. Now, if there is something there it all applies to field points because they don't take much effort to spin up. If you add an (adult) broadhead things change. Due to the increased mass and the added resistance of spinning a blade, rather than a field point, it takes far more energy to spin up the arrow, resulting in a different ratio between deceleration due to spinning up (helical) and deceleration due to more flight time flying "sideways" (straight fletched). In short: Do helical fletched arrows slow down relatively more with broadheads than they do with field points compared. (Even though in absolute numbers it may still slow down less due to the heavier arrow.) And how does that compare to straight fletched arrows? Can you compare deceleration between 0-25 yards and 25-50 yards (preferably on the same shot) to find out if there's something there? That'd be interesting! Wow, reading back I very much doubt any of that made sense, but I can't do much better. If I come up with a better way to put this I will. Feel free to make fun in the meantime...

[@mikemcgill3998]

I get what your saying. A circle(field point) spins easily because there's no sideways drag. A flat board(adult broadhead) would have force against it, as it spins sideways through the air. How much energy does it take to spin the broadhead? Am I understanding you correctly?

[@the_sharp_carpenter]

If you pause the video the radar has the speed readouts every 10yds so you can see what you are asking for as far a initial, middle , and end of flight. I'm sure that changes with a broad head. kzbin.info/www/bejne/gGGmh2eFosuIfZY this is a great video for vane speed erosion.

And…your high helical rig had larger vanes. I’ll be my high helical blazer 2 inchers aren’t costing me any speed vs. straight blazers. Really appreciate this video and your approach to data science. Thanks!

Don’t be stupid

[@MikeyWoomer]

Maybe someone else asked this already.. but what was the degree of the zinger fletch.. and was the zinger a 3 or 4 fletch and... lol.. was thr zinger one of the new ones or one of the old style? I am a fan of zingers and vanes and feathers.. shoot them all lol. I love to fletch and play around with fetching. I just started to shoot the new easton bully vanes. They paired up with bohning to make a great vane. It's the profile of a blazer vane with the stiffness of like a hear vane. Great video Troy love these

[@londonforge]

Try out StarrFlight FOB !!!!!

[@kodiakfisher]

It appears to me that almost all of the momentum gain happened at launch when comparing heavy vs light and that gain obviously would be evident at 10, 20, 30, 40 also not just 50.

Fear Of Change F.O.C. 😂❤

[@tonyviers-de9qi]

Great video. Can you a test at 100 and 120. 4 arrows, 2 small vanes , 2 bigger vanes ( same material) each with one helical and the other off set? I like your 50 yard data since that is a great hunting distance…( for a good shooter)…. But curious about longer distances ( field points only)

[@MrAdobediaz]

i wonder what a FOB would have done in this experiment...asking for a friend...great info

[@revskull]

Don’t know if the variable would be that valuable, but I shoot offset 4 fletch vanes..I ‘think’ I gain the stability with less drag..??

[@jolookstothestars6358]

Cool stuff guys! Next time invite me over I'm just across the border in Arkansas. ; ) p.s. I wonder if the high helical acts like a propeller??

[@seantnper881]

So then with a 700+ grain arrow bare the same results? Or a 1000 grain monster? I’d like to have 50 1000 grain arrows ready to go with some bishop steel… buuuut that’s really expensive to do…

[@olegchernenko6712]

How do u like Zinger in terms of stability and loudness?

[@RanchFairy]

More we explore this aerodynamically. It appears we would prefer a larger fletch over smaller to keep broadheads flying Field points are liars I like the concept. I KNOW the noise thing is a paper tiger Because we NEVER see consistent movement of the animals Your study on you tube begins now! And k shoot feathers - they are the loudest - but things still die and the reactions are completely unpredictable Choose perfect arrow flight and sharp DURABLE broadheads FIRST

[@hikingwithaviking8529]

I have noticed long vane (2.5"+) and a full hecial on a faster arrow (280+) balloons like crazy. Using a 2"-2.3" with a true hecial achive better results for righter groups at speeds up to 290fps from what I have seen.

[@yourmomma2995]

i try to keep my arrows under 400 grains, i honestly can't remember the last time i didnt get a pass through, with my arrow buried deep in the dirt on the other side.....maybe when i was a little kid shooting a 40lb bow. but i only hunt whitetails, if i was to go to africa and hunt larger game i may be forced to use a heavier arrow, i would have to do some testing to see.

[@windellpenton]

I see those concerned about component size .. I think RF needs to consult with someone about manufacturing a tungsten insert .. 😎

[@hutchieboy242]

I think the speed sustained with the 4vanes at 297 was a significant point. It was the less speed decrease of all the arrows. Helpful to the Bsrebow crowd. Does 4 vanes help at that range?

[@ericwiitala5407]

That's a fantastic question. Are there pay phones anywhere anymore? LOL!! 😁👍

[@shootingatshadow]

You really need the same velocity but with different fletching configurations. This way you can get the initial drag the same between comparisons since drag is a velocity squared based function. This way you're only comparing mass vs fletching configuration. Not mass vs speed vs fletching configuration.

[@RanchFairy]

Agreed. But you're quite advanced and we want the average folks to understand this. More to come.

[@shootingatshadow]

@@RanchFairy I watched a bunch of your other videos, and really good job. I have changed my setup a bunch with amazing results. 519gr, 16% FOC, 292fps with a 125gr Kudu point.

I have another take. Tim is not normal. He's absolutely on another level from average people. So he wins. Yep. I'm trying to help the other 99.9% of humans with average bowhunting skills. But they might be doctors, or lawyers, or tradesmen, accountants, the best internet marketing person ever, incredible at leadership, etc. But they aren't the .001% who are amazing with a bow or other weapons. I mean, its a thought.

[@grayman7208]

14:00 when testing for comparison ... you must only change one variable at a time. no fletching and different weight are two variables.

[@Kurtdog63]

Guessing there is a point of diminishing return for arrow spin, extreme helical, verses straight fletch, concerning accuracy (for broadheads). Bullets of various velocities, weights, calibers, and lengths are definitely spin picky. Also, ever try to throw a foot ball without spin? I like somewhat large feathers (4 inch) with some offset, (my EZ fletch is 4 degree) not only for arrow stabilization and improved accuracy, but the offset, larger fletch has a thicker profile from the rear of the arrow and gives a better visual of the arrow in flight. Lighted nocks are awesome, but they sometimes fail and and don't always show up that well in bright environments. Two fluorescent chartreuse feathers and a dark cock feather can give somewhat of a variable contrast regardless of the target background or light conditions.

[@jasonstirland]

If the test is supposed to be of fletching configuration, then that is the only you should be changing with each shot. You can't change arrow weight, arrow spine, and fletchings and then make a determination of how just the fletching configuration changes velocity

[@RanchFairy]

Helical Fletch Heavy vs Light Arrows.....in the title? And yes I can do a test of fletching where we change the ballistic coefficient to see what happens. Because that's what we did! Find anyone else in archery even daring to try this type of testing, with a lab radar, to keep the lying and "calculator" guesstimators honest. I look forward to your reply.

[@jasonstirland]

Easy tiger. I'm not arguing your data is wrong. I'm in the high FOC club. But you tested speed errosion as it relates to mass, not fletching configuration. Look at the beginning of the video when you show us the arrows. Your straight fletch, is a different weight, different type fletching, and a 4 vs 3 fletch. All different from your helical. To test speed errosion as it relates to helical vs straight all those things need to be the same. It's all splitting hairs, but if your going to do it...

[@williamfaltynowski7593]

Have you ever tried a 2 fletch arrow with a 2 blade single bevel broadhead? Just curious if the fletch to head offset would allow it to fly straight, and or if it would work at all....

[@jfreak7589]

What's the square root of 357.34??

[@RanchFairy]

Fletchings create drag!!! That what we learned.

[@ThatJamesGuy88]

Stranger on the internet just told me I shouldn’t go from a 440 grain arrow with 3 fletch to a 500+ with a low profile 4 fletch because of drag. I just want to play with a heavier arrow. 🤷‍♂️

[@RanchFairy]

There’s the math

[@timl8302]

The reason feathers are slower is they're wider than vanes. My Ozarks with is .088.

[@RanchFairy]

UH...no.....my feathers are .5" tall by 1.5" long but that has nothing to do with it. God.....did this. Feathers are more resistant to airflow. See, birds have to fly. If the feathers didn't resist air, then birds would not fly.

[@timl8302]

@@RanchFairy That is not what I meant. Let me put it another way. Vanes are thinner than feathers. Thus, less air resistance. Although, vanes don't fold around branches like feathers.

[@RanchFairy]

@@timl8302 feathers must drag or birds won't fly. That simple.

I'm going to ask a dumb question but wasn't the arrows going faster when hit the target at 50 yrs with the 100gr head than the 300gr head at point plank from first shot I mean a considerable speed difference

[@RanchFairy]

Yes - of course - launch speed was much lower POINT of VIDEO is how much erosion occurred - from launch to impact. See my Kinteic energy and momentum at 60 videos - those I study the down range “on meat” impact energy. I was amazed

[@Jimbowiejr]

As a railroad engr I can tell you that mass matters. A car running into the side of my locomotive vs a logging truck at apt the same speed is totally different amount of energy produced. Warning :: No one was injured during these accidents. X Do not try this at home or away from home.🤔

[@WM-jy9dz]

to stick with this analogy: you would need a VERY big bow to put all the KE into a locomotive at launch to get her from A to B 😁. Comparisons between arrows and heavy vehicles like cars and trains need to consider that the later ones don't rely on the launch KE as they have alternative fuel recourses on board that maintain their speed....if we would pack fuel into an arrow it would be a missile and then it would be all about speed 😂...

[@austinphillips9966]

I’m shooting 481 grain arrow with over 20% foc 250 spine I wonder what my erosion would be

[@WM-jy9dz]

you need to measure your launch speed - from there you can estimate the losses pending on the distance and your fletching setup with the drag deceleration, e.g. a moderate 3 vane fletch will cause a deceleration in order of approx. 2000 millig (boy do I hate this imperial units living in a metric world - fyi 1 meter/square second is equal to 101.97162129779 millig-unit); for feathers it will be in order of 3000 millig. For a more precise approach you would shoot the arrow through a chrono at point blank, and then through the chrono at 50 yards (or whatever distance you are comfortable with).
