Thank you, Thank you, Thank you. The most misunderstood, misquoted, and maligned factor in the Study. Well done, Sir.

I agree with RF that confirmation bias drives a lot of the haters on this subject. I've been bowhunting for 47 years and have seen some pretty crazy, almost unexplainable things happen when an arrow hits a deer. As far as breaking bones, one complicating factor seems to be whether the bone, especially a leg bone, is loaded up under strain/tension when that broadhead hits it. I have had a couple of hard quartering away shots that hit the hind quarter just as the deer was loading his hind legs to bolt and the femur just shattered in both cases. Conversely I have hit a small buck right in the shoulder blade above ball joint just as the deer was raising his leg. Knocked him right off his feet and the arrow just fell out with no penetration using a Muzzy 3 blade head, and he just got up and walked away unhurt. I agree 100% that if I had been using a heavy arrow with better mechanical advantage it would have blown right through him. For all those who have had 147 kills on 147 shots and saw every one fall within sight, well God bless them. For the rest of us who have had some sleepless nights after a not so great hit, we'll keep looking for ways to get better and do better. Keep up the good work, Troy.

Uh guys... the science doesn't lie! My setup is one that I'm confident in. Sirius Apollo 250's, 4 fletch, 100 grain insert, 200 grain grizzly stik massai. Shooting 30" draw at 65lbs. Out of an Elite Remedy. Absolutely the best flying setup and hardest hitting one I've ever shot. Either shoot adult arrows, or don't! But don't hate on the guys that have done decades of research proving the theory

495 grains at 16% foc and 265 fps, easily through both deer shoulder blades. 430 grains at 280 fps with magnus stinger split the ball joint on exit. Both broadheads were sharpened with fairy dust.

I went from shootings flappers on a 400 spine arrow to a magnus on a 300 spine arrow and it has significantly improved my on meat performance after diving into RF'S content quite heavily and its amazing how much i was leaving on the table shooting 70 pounds and never getting a pass through on 10 deer to getting 5 pass throughs on the first 5 deer i have shot since the change its mind boggling the difference

I appreciate all RF Mr. Ed has done for all us bow hunting enthusiasts. In particular this clarifying video on this bone breaking study. Ranch’s’ reading reminded me of my childhood when my mommy used to read me a bedtime story. May be a good idea to read from Dr. Ed’s studies every week! Keep’em coming RF!!!

The way I see this Troy, is that they don't know or don't understand this stuff as much as you and Dr. Ed do and they don't like it. That makes them feel bad, or just plain stupid. So they go out of their way to prove you wrong and that makes them feel better about themselves. I've seen this so many times in my 77 years here. The only-problem here is that: You can't argue with science! Jim

Blue collar man here. I dont have time to deal with bones. The deer is dead when i get a shot thats why im at 700grains single bevel haha

This is very important to us traditional archers.

As a physicist, one huge thing that is not obvious to non-scientists is the premise of probability. Usually people will conceptualize things as being either totally random or totally deterministic. The premise that you can rigorously predict and determine the *probability* of something occurring is a subtle enough premise that you should expect some challenges in communicating such things. You don't actually have to be stupid to misunderstand something as subtle as this.

Thanks RF. Ive gone from 465 grains to 600 grains with a 250 spine. Im loving it.

I was very glad to see The Hunting Public Crew, start learning from and testing with you. Those guys will excel! Christ bless!

@ranchfairy youve helped me out tremendously, thanks for being the martyr for heavy arrow/high foc. Thanks to Dr. Ed, your research is tremendous for everyone. Shooting 73.5lb, 28inch draw, 713 grains with 21 to 22% foc. Also thanks Sirius!

I shot a small cow elk on a quartering away with a gold tip hunter 340 and a g5 fixed blade at 40 yards and maybe got 12” at best into the elk. I will never do that again. I did get the elk but it shouldn’t have went as far as it did. I’m hoping I get a shot this year with my current improved setup. The single bevels are flying like darts. I’m getting excited for September!!!!

That is so easy to understand.... Broadheads can and do break bones and they do that below 650 grains. BUT at around 650 grains ALL broadheads will see a sharp increase in the ability to break bone. Simple to understand. Shoot a light arrow into you target. Make note of the sound when it hits... Then use a heavy arrow.. A TOTALLY different sound. Whether you are shooting a vertical bow or a crossbow.

Hi, Thanks for your videos and knowledge on the bow efficiency to ethically harvest animals. I agree fully with Ed Ashbys research and testing the lethality of a bow and arrow. I understand the 650 grain threshold. The one thing not mentioned is the speed of the arrow he was using. I use a Magnus stinger and believe thye pocess 😮enough structural integrity to breach a whitetail deers bone structure with the accept of the shoulder knuckle providing you have enough momentum to penetrate efficiently and follow all the other thing like good arrow flight, a strong arrow and as much front of center without sacrificing arrow flight. I myself shot a 480 grain arrow and generate a out 70 lbs of kinectic energy and .6 momentum 19 percent Front of center with a 60 lb compound. I'm 62 and cant accurately shoot 70 lbs anymore. I'v been bow hunting for over 40 year and really never had trouble breaking ribs to get into the vitals I never experienced the scapula causing bad penetration it is actually softer than the ribs. I only take slight guartering shots. I don't risk bad angle shots I think the setups you are promoting are definitely are more effective and are top of the line the only problem for me is the cost to effectively achieve this amount of perfection. I believe I'm doing my best to ethically harvest Whitetails. Maybe someday I'll be able to financially afford to upgrade. Thank you for the knowledge you share. Good luck and safe hunting. Ralph

Great video and great comments on confirmation bias. It has to be maddening to discuss this with people intentionally trying to misinterpret the study and never providing their own extensive research. Thanks for the education.

I appreciate the ol' RF. Especially the tuning vids and he will actually respond to an email clarifying anything that is unclear. Last year with the arrows/broadhead combo i had I shot 590g. This year a different combo going about 550, next year a little lighter. Maybe the next heavier, it just depends on what works on my animals and how I shoot each setup. Its a constant journey always tinkering.

I hunt out west from 20-60 yards which is really all you should be taking game at no matter east/south/north/west responsibly with a bow and arrow. I have two arrow configs, 505 and 592 grains.. thats it. I carry both in my quiver and know the holdovers for both in those ranges because it's the only arrows I use. I practice with an iron will field point which is spot on tor their single bevel bh's out to that range and a four fletch 3 deg helical. Money on anything in NA and prob abroad as well... you're a good guy Troy and I watch every angle of bowhunting. You did your perspective with real data and that can never be discounted.

Aside from your entertainment value, I keep watching your chanel (or any other chanel you're a guest on) because i ALWAYS learn something new. Thanks and keep being you RF

Thank you “common core” education. Promoting stupidity in our youth. Good job Ranch good video

Thank you for another brilliant video while explained. I am afraid you are always going to get the demet's who want to disprove everything that they read. Even though they probably did not read the entire study that doctor add dead. You and the rocketman are brilliant. Putting the information in a way that everybody can understand. 👏👏👏🇺🇲👍🇬🇧👍

This really clicked with me, extremely interesting!

Thank you for all the info. I am an old fart that was heavy into archery hunting until a work accident. I was devastated. Then along came crossbow hunting. But the early crossbows did not meet my standards for my accuracy. Crossbows evolved, now I hunt again. Thus, I am trying to teach an old dog new tricks. I love the info you give us. Back in the day we would hunt with wooden shafts and gluing Bodkins onto the shafts after our spin tests. We quickly found out that the long narrow tip was not a good idea. We blunted the tips and sharpened the tip into a tanto tip (if I was smart i would have patented it). My uncle was older and was only able to shoot a recurve at 50 pounds. He shot a deer at 20 yards and had a pass thru. We were amazed that the arrow had shattered both front shoulders! It's people like you that enable people like me to still keep on keeping on. Thank You

Awesome explanations. Based on my bow speed @ 70lbs I was losing kinetic energy with 650gn but happily settled on 565gn for best results. Punching through 44gal drums easy

Ashby is awesome and really helped open a focus to FOC which before his,really wasn't such a big topic. Kudu's to him. I still stand by, as a compound bow hunter, I follow after a 3 headed monster. KE,FOC,Momentum. Many people got off the KE thing we were on pretty hard in the early 2000's. KE is still relevant. KE is going to begin with your bow poundage capability to propel mass x speed. Lower the poundage, and you lose that mass by speed. They all are connected and work in unison with ofcourse a well tuned bow first and foremost. So my bone breaking increases from when I went from 70 pounds to 80 pounds. Don't know any of the statistics, but I examined plenty dead animals including maybe hundred animals dead with a Easton FMJ and never a catastrophic failure like we seen online. I'm settled on a 580 grain arrow 5mm 3K weave arrow shaft with a 50 grain stainless half out and 150 head on my 80 pound PSE EVO EVL 32 80% Let off,smashes any bone on any animal on North America easily. I have gone as far as 660+ total arrow weight using a 6.2mm arrow and really smoked bones too. The issue is, it's so heavy, I don't have enough tape on my sight to get much further than 60 yards. But a great arrow nonetheless,especially for hog hunting over a feeder. I don't know the statistics. I read and watch videos like this and get some help, Troy helped guide me because increasing FOC on 80 pounds isn't so easy. You tinker,and expreimen. I have the added advantage of a hunting lease year round hogs,and plnety of them to try things out. When deer season comes around, all my equipment has been proven to me and established. So thanks to guys like Ashby and Troy for just EXPOSING you to new ideas from proven scientific methods. It's up to you to fit it in with what you do. For me, I have 2 arrows that tune out of 2 bows for 2 different purposes. I'm happy. Question remains what would I use on a Elk or Bison ? I think both would work great,one will have distance limitations.

Hopefully I can send you something this year. Spent a couple years tinkering. What I'm shooting now is what I'm going to stick with. Getting really good arrow flight and consistency with a 610 gr, 5mm Easton Axis w/ 150 gr left bevel Iron Will (250 gr up front). Fletchings have a left helical to match the bevel and natural rotation of the arrow. Hopefully a mule deer will cooperate and I'll let you know how it works.

Thank you Ranch Fairy! Keep em coming, I'd watch some videos of you fishing too if you have or post any

I love watching your videos you and T Bone both preach FOC and it’s awesome I have been tinkering the last few years with foc and I have noticed a difference between higher foc and just slapping arrows together n hunting like I used to.

If anyone has ever seen the old 1930’s? Howard Hill African bow hunting expedition movie you will see he uses a very narrow long two blade head. Wooden shafts naturally. No idea of the weight. Point is his points had a great “ mechanical “ design for superior penetration. Long and narrow. I’m assuming he used very heavy shafts with a 70-80 bow? He wasn’t naive enough to use a light draw weight for African game. Troy, love this video because so much information is based on hundreds of animals examined after the kill. No guessing, research and facts

I watched my cousin who was shooting a 58# compound bow (some Bowtech bow from about three years ago) shooting a Rage Hypodermic mechanical broadhead hit an Elk in a rib bone at 18 yards and it looked like the arrow BOUNCED OFF THE ELK? It had about an inch of blood on the shaft back from the MANGLED broadhead. Now I would never ever shoot a mechanical broadhead at an Elk, but he would and did. The following year he was shooting Helix and hit a bull at 21 yards up hill. He drove the arrow through part of the elbow joint and went about through the heart. Now you know a heart shot doesn't usually produce an instant kill. So we walk up on the thing and he shoots it square in the ass. It wobbles off to about 45 yards and stands broadside. With this shot he smokes it behind the shoulder a nice double lung shot. Arrow blows through like nothing. At the point the Elk explodes down hill (steep down hill) and piles up about 80 yards away on the only flat spot on that mountain that I think existed. I'd like to note that everyone we ever talked to about hunting Elk (including me) begged him with tears in our eyes to NOT shoot an Elk with a Hypodermic mechanical. I still shoot a Hoyt Super Slam legacy, 73#, 30" Draw, 2315 with 125 muzzy 3 blade. I'm shooting 218fps. Finger tab.

Ranch Fairy is awesome! Keep up the GREAT work Troy!

Went from shooting Walmart Specials..cheap Blazer Vanes with a cheap expandable head.. to a RF Apollo 250 spine at 29 1/2 in w/ a 125 Single Bev: totaling 578.06 grs ( I wanted to go 200 single bev, but my 2012 Bear Strike would not allow it) I get laughed at a bow shops, I get "you're shooting javelins", and "you listen to Ranch Fairy, he's a quack only shooting pigs at 20 yrds"... when mainstream "finger on the pulse" type people are telling you you're wrong... I want to listen to Troy even more....yeah I used the last sight tape on my Tetra, but I'd rather have a HEAVY BadASS perfectly paper tuned with a Shit ton of Momentum than what I previously was using.. Nobody taught me anything about Archery Hunting, I stumbled onto Mr. Fowler's channel and I never looked back.. NO the arch out to 60 yards isn't hitting the treetop, no it's not limiting.. It makes me more confident, makes be a better hunter, and makes me cocky as fuck when I go into Bow shops and outsmart either the Flat Billed 5'6 neck beards and/or the white hair in the ears fud boys when they try to tell me I'm "shooting the wrong arrow"

There will always be people who do not read the full article

Still amazes me how people try to discredit or disprove Ed’s studies. I can never understand how today’s equipment fails at killing in such close ranges when these things were used in war to kill people in plate armour, chain mail and heavy gambeson at 400-500 yards and people say 3-6 inches of penetration is okay or an arrow deflects at 60 and they say thats hunting?!?!? People have no idea the weapons that they “use” and they make them so inefficient and ineffective. It really blows my mind. For me though i think there is too much emphasis on the grains. I get it i know why thats there but i think the focus should be momentum. Because the kinetic energy machine plays a HUGE factor too. And i don’t think its fair to ignore this. Different draw weights different draw length’s different mechanical advantages will all be different. Example a 30 lb draw recurve will pass through and animal with a 650 gr arrow because the momentum out of that is around 0.6-07 a compound with 80 lbs can get 0.6-0.7 with a 540 grain and so on. I really think its the slugs of momentum that mean the most and if you want to use a mechanical head you need more momentum than if you used a fixed head. I really think once you have all the factors: arrow flight, structural, integrity, head sharpness ect, ect, getting to 0.5 and higher preferably of slugs is all you need. There is a diminishing return which occurs with anything that launches a projectile. And the kinetic energy machine determines what that is. My crossbow did not like 630 grains they do not fly good and goes way too slow for the scope to be accurate. (Could have been how i made them) but 565 is still 0.7 slugs just like the 630 were and it does better it does it a little faster and the momentum is the exact same. You need to test your equipment to see what is right for you and your kinetic energy machine they are not all the same. So I understand the 650 bone breaking mark but what is that in terms of slugs? 0.6-0.8 range? That Troy would be a thing to look at.

I have one setup that works extremely well on all critters I hunt. That means everything up to a cape buffalo, but not a cape buffalo. And that is a 650 grain arrow at 260 fps, with a FOC of 15%. I have used that setup for 15+ years with great success now. I have broken numerous humerus on different critters with this, including elk sized ones. If the critter is rather small, I use a Slick Trick Magnum or even a mech like the Spitfire Maxx. If the critter starts to become medium sized, like a whitetail doe, I ditch the mech and either use the Slick Trick, a Magnus Stinger or even a Cutthroat. If the critter becomes elk sized and bigger, I ditch the Slick Trick and the Magnus Stinger and only use the Cutthroat. The main reason for why I don't use the Cutthroat all the time, is because they are rather expensive broadheads to lose if I am not able to find it again after the shot as I always have the arrow flying on the other side of the animal after a shot unless I hit the spine. The same happens with the other broadheads as well, but they are far from as expensive if I am not able to find them again. I do most of my hunting from the ground still hunting or stalking, so losing the arrow after shooting an animal is not uncommon.

Came for the info, subscribed for the sarcasm. Planning to buy some adult arrows for this season

Nice flex. I see that green bottle in the background 😂😂

Very excited to try out my high FOC set up this season! I have followed RF for years. This year I had a absolute stud of a whitetail show up regularly. The location is a perfect area to hunt traditional. So I plan to shoot a 700+g tradstar this year. We live in southern Oklahoma on a 10,000acre ranch so hopefully can get some test subjects in before deer season.

Crossbow running Sirius Phoenix 22 inch carbons, 125 grain inserts and Ranch Fairy (tuffheads) 200 grain single bevel. 625 grains. So am I almost there ? LOL. Gonna keep what I got, this all works fantastic for me so far !

Hey Troy, you're doing an amazing job... but the realization just hit me, as I'm turning 30... that apparently 2008 was 15 years ago. Do you know if the Ashby Foundation is in the process of a 2028 update, using everything from blazing fast, lightweight arrows, to the heavyweight bruisers... mechanical and fixed blade? I feel like technology has changed so much, especially in the past 10 years, that it's tough to quantify. I'd be surprised if anything could beat the 650 grain fixed blade... but it would be awesome to have a more recent update, that uses all styles of archery equipment, to reach a definitive conclusion. I'd love to see that collaboration... not just on big game, but deer, and pigs too. Keep up the great work, man! I just received the 200 grain broadheads from Sirius, and they look incredible. One more paycheck and I'll order the test kit.

I really like your channel. I’m learning a lot. Having to forget many things I thought was true

Trying to get hunters to understand that something increases odds of success or lowers odds of success instead of absolute results is difficult. Statistics don't lie, people just misinterpret them haha good clarifications!

The intro is AWESOME!! Hahaha. Great video, well said..

You get one shot. Maybe less then a handful times in the season. Make sure it counts and your able to put meat in the Freezer.

How did Howard Hill get by without the book of "Hunting arrow weight for Dummies" I know "COMMON SENSE"

Good job RF. . Never seen so many know it alls outside of archery. And i do medicine for a living. Lol

I started 400 twizzlers.. moved up 300 spline 150 Magnus BraodHead Scalpel Sharp . 540 grains. Still a bit shy of 650 .but 540 and sharp broad head.pass threw !

Last season I went up in arrow and bow weight 76# hoyt ventum pro 33 arrows are rip tko 250 spine with 75g inserts, 15g collar and a 200g tuffhead evolution (580g total) I've never seen so much arrow penetration. Took a quartering towards shot and broke 2 bones on a whitetail. The first was a rib. The second was after the arrow exited lower opposite abdomen, struck and broke its hind leg. The arrow continued going and was embedded into the ground. Total tracking was approximately 50 to 60 yards. I'm strongly considering bringing my bow up to 82# and switching to 200 spine sirius Gemini with 100g inserts and 200g rf single bevels

Ok ranch fairy I have a story you might fund funny. Yesterday I go to my local bow shop ( macks Prarie wings) to get my arrows 4 fletcher and add a 100gr insert to replace my 50 gr, putting me around d 520 grains. The guy who runs the shop whose name I will not mention because he is a reputable guy in the area, refused to put the 100gr insert in my arrows and I formed me he shoots twizzlers and flappers with a 400gr arrow and does fine. So it looks like I'll be ordering adult arrows from you

HAHAHAHAHAH NICE! Finishing with the hunter shooting a goat length wise through it's entire body and saying yah, 650 gn's! LOL

Remember what Chris Rock Said .. "Readin is for Rich People" 😂

I never heard a “boom flopper” say they are going Elk hunting and need to buy a 22-250? It’ll kill them too with perfect shot placement though right?

Love the content. Keep it up!

I have definitely noticed more penetration with my flappers by adding a 100 gr. Brass Insert.

I’m not pandering, but I don’t worry anymore where I place my shot, calm down I still shoot for the vital v but I really don’t stress over all the stuff I used to worry about , and another awesome effect of my heavy arrow is my bow is crazy quiet!!!

I know all about there is! Watch the young man run, he'll be runnin' against the wind. Lol!

Heavy arrow effiecentcy is pretty easy. What do You want to get hit by, a hardball at 80 mph or a tennis ball at 90 mph? Which is going to break more bone? Which will fly farther.? Which will be less effected by the wind or some odd twig?

The problem with hunters, especially these kinds of "keep everything stupid simple and never try to be better" is that they aren't scientists, they dont have a STEM background, they dont understand how numbers and data works. I wish Ashby just posted the raw data, an arrow hitting game is such a complex process with so many variables that its difficult to make any concrete conclusions about anything.

I'm shooting really heavy arrows by accident. I was trying to build a 665 grain arrow, but I cut my first shaft too short and I'm too cheap to throw them away, so I added heavier points until it spined properly. My prototype arrow ended up being 740 grains. And now that's all I shoot out of my 60# recurve. I could shoot lighter, faster arrows...but why? Thanks for all that stuff you do RF. Great videos. Very informative.

The other channels trying to play off of ur content are funny too saying ur too radical with heavy setups and they start preaching a "middle of the road" arrow telling ppl that's the best way to go. Meanwhile, their videos show them rarely getting pass throughs unless the animal is less than 12 yards away 😂

35 year detective. A good investigation examines all available evidence without bias and works forward to find the truth of the matter. A poor investigation first jumps to a conclusion of what the result will be and then only includes biased evidence that supports that conclusion - the end result is the truth gets left behind. A lot like politics.

Keep it up RF! Truly, I don’t believe archery hunters will ever agree. However, when they hit a deer in the scapula and find their arrow (without the deer) that only penetrated 2-3 inches, they should build a pan B setup. Some folks are stubborn. Keep buying Chinese junk steel😂

Sure a lot of "-ish" and "about" and "approximates" in there. How can you assign a specific weight of arrow to "bone breaking threshold" without any regard for speed, KE, and momentum? A 650 grain arrow shot from any bow setup will break bone better? We are still talking about his tests performed with long bows here? He didn't find any broadheads that could penetrate bone 100% of the time at less than 650 grains with a longbow? How about with a modern compound? How about on different species of game? Do I need 650 grains to breach bone on a pronghorn? On a whitetail? On a cottontail? Or are we just talking about water buffalo and applying that data to every single game species? As far as mechanical advantage for broadheads, the standard for measuring MA treats it as a ramp with something being slid along the edge and doesn't take into account that the broadhead blade is cutting, not pushing material along it. Bill at Iron Will explains it better than I could. I'll stick with my 450 grain "Plan A" Pixie Sticks for North American game.

The bottom line people are afraid of change!

That's science these days. Start with a conclusion. Like "safe and effective"

Seems simple enough to understand to me

There’s melted Snowflakes all over KZfaq now lol thank you #RanchFairy.

Excited to watch! so i hear a lot of noise that ashby studies on physics doesn't apply in a world of compound bows; that it only applies to trad equipment. Was wondering if Troy has ever unpacked what seems to be a common misconception.

Surprising how many old guys I talk to and really good archers that still stick to the super light arrow with a flapper on it. Of course they have success because that’s all they’ve used like what? They completely ignore their failures that some could’ve been avoided with a little heavier arrow with a fixed head.

Bone breaking is a function of psi not necessarily mass

If you get time, I've NEVER seen a video on single bevels breaking bone with a realistic poundage traditional bow 45-50 lb. I wonder if there is an energy threshold for the bevel to be relevant ?

in 95 percent of deer ive shot and recovered bones where cut threw not broken. shoot more like a 450 grain arrow cant rember exact waights atm and dk where my scale is to waight them. but the other 5 percent there was atleast a part cut into bone then bone shanped likly due to weakening and then strain as animal ran. you can ezly break bones when have a point of stress that will focuse forces aplied to the bone. bone is really no difrent that a weld assembly. if there a stress riser chance of failar greatly goes up. and to untrained eye a half brok bone may look like a fully broken bone.

Half way through. That's pretty simple science 😂

love your content.

@Ranchfairy I heard you say in one of your recent videos that if you have bleeder blades up front they are not as effective as if they were in the back. Any feedback on that would be appreciated. Love the videos man! 🤙🏾

I like to tinker, so I landed on a setup right at 800 grains. People say it's too much but I had fun and it was successful. Right side scapula, rib, soft stuff, rib, left side scapula, not a sound. Spun away from me at the shot arrow pointed back at me on the ground. 2 jumps and lights out.

I thought of some anatomy videos there.

Love it. Thank you

Sounds like a lot of theory…the same type of theory that says you can’t get a long broadhead to shoot as accurate as a mechanical. It’s all irrelevant without testing data. If you cannot show how it matters on the equipment being used today vs just what is ideally better then what’s the point? And if it’s so close from a game recovery aspect that the answer is “it’s too small of an aspect compared to all other variables in a hunt” then I’m not paying good money to change. So let’s see the data or just admit you’re guessing in practice.

Good stuff!

That last viewer video was excellent choice, exclamation point, etc… any one arguing with heavy arrows work better when perfection doesn’t is simple ignorance. Just keep shankin some of those big pigs for the cause.

Can we define what is “Heavy Bone”? I’m assuming a whitetail scapula doesn’t fall into this category, but a humerus or knuckle probably would? Whitetail ribs definitely done, but elk might? I think this would clear things up for many people. I shoot an 8 factor arrow that is 480gr and it will absolutely double shoulder blade a whitetail. Now what happens when it hits an elk humerus, I don’t know.

the ignorance I hear people spout off about some of your videos blows my mind. so many so you only say to build 850 grain arrows and I tell them they are full of it. the 550-650 area is money for most people

You should make a video and read some of your hate mail!? That might be very entertaining! 🤣😂🤣

You need a shirt that says "page two, paragraph two."

Nice way to end the video!

They used an Asiatic Water Buffalo @ 20y. Besides ball joints & the bone area around the ball joint are heavy bone on a whitetail, Mule Deer & ELK. The question is what is the definition of 'Heavy bone & 'Medium bone'? Is it a diameter or density? I am just asking to get a sense of proportion as to effectiveness of a 500gr -600gr. on common US/Canada big game leg bones. Feral Camels & Cattle excepted. I'm just trying to figure things out from comparing Cape & Water Buffalo at short distance to common quadrupeds game. OK, I'll even add sheep & Mt. Goats to the mix. Yes, I've read Dr Ed starting years ago.

Well u know ur doin something right when the haters are talking!! Do u boo boo😂

When I mention this study to people, the common response I get is "well that's with a recurve, not a compound". How can I respond to that?

Completely agree with the Ashby stuff and everything you do RF. Still waiting to see if this aspect can be expanded on with today’s equipment. For instance, 605 grains going 270 could have the same bone breaking ability as say 675 going 235? Point is certainly speed is going to have some effect and finding that happy medium. And I’m sure testing this would be laborious.

Ashby had to be shooting aluminums right? 2219, 2317, and 2419? I wonder if the 14gpi had a major effect of the 650 factor being from the weight or the arrow build being so high, because he had to shoot stiffer spine aluminum shafts that weighed more?

k knuckle heads! Its already been done. Learn from the best, Dr Ashby. Let us know when you are shooting a 90 pound long bow and a 1200 grain arrow....then open yer pie holes. Lol!

I need some help/advice from anyone watching. Im about to order a ranch fairy bareshaft test kit but not sure what spine. I shoot. 27in arrow at 57-60lbs. I was going to do the 250/300 but wondering if I need to get the 300/350… every dumb spine chart says 400 but I know that’s too high. Let me know!

Rain in Texas in July? I thought that was a myth lol.

397grains will do all the bone breaking you want at 70lbs got the evidence all over my channel love the science tho and yeah i dont read 👍🏻

at what speed were these arrows tested? and how much does this have an effect on grain weight? can you use a lighter arrow that's faster? what about the bows poundage? 50 vs 75 vs 100lbs... i have so many questions lol.
