Definitive arrow study- Easton

[Beendare]

Finally, a scientific study on arrows including FOC by the premier source- Easton

Shooting machine sure, slo mo camera and multiple engineers calibrating and documenting everything ...but then they shoot both FP's and BH's and induce a consistent 2 deg torque on some shot to replicate a shooter.

One of the key difference between this and the other precisioncutarrow study in 2025, they de tuned the bow to a 1.5" paper tear....and they didn't look at FOC. I suppose the de tune was to replicate the avg bowhunter that doesn't tune his equipment? I don't know. Seems like it was done to test max fletching correction.

I've seen so many other garbage backyard arrow studies I'm looking forward to this. Results aren't published yet....but from my experience, I don't think the high FOC guys are going to be happy.

Whats your prediction?

16:50 "FOC matters" But what FOC will matter?

I never shot high FOC and shot more of what would be a standard target FOC (Easton recommended) and never had any accuracy or performance complaints when shooting broadheads.

 

[Beendare]

Actually, he goes into more study parameters here and the torque introduced to the bow and why.

I'm bummed. He detuned the bow here in this study too for a 1" tear. I know a bunch of guys that would be appalled with a 1" tear.....heck, I don't get a 1" tear with my recurve.

Look, I'm not trying to be a naysayer here. It's a fantastic study with incredibly accurate calibration and meticulous data collection. Well done.

BUT....He obviously thinks there are a lot of bowhunters that cannot tune or hold consistent form. Maybe he's right, I dunno?

He leaves us hanging on the results.

I'd say so. Just like on a public rifle range I'd bet 90% can't shoot very well and I'd bet 90% of the masses don't know a thing about how to tune a bow. The shop does it and hands it over.

Yes he does the little bastid

I think the reasoning to put the bow out of tune was to make the results more conclusive for a more forgiving setup.

If everything is perfectly tuned every time then it will be a lot harder to differentiate which vanes, broadhead, FOC is better. When you introduce a slight error then it should become obvious quicker and more conclusively which stand out.

Feel like there's going to be a "FOC Node" where things work well at most speeds with a fixed blade. My Scientific Wild A** Guess (SWAG for short), is going to be 13-17% with absolutely no evidence to support this position.

This was not a Easton project while they did donate a bunch of resources it was a independent study.

I definitely went deep down the FOC rabbit hole. 692gr with 23% FOC.

I am much happier with my current 480-485 gr build no matter what the FOC is.

Yeah I was under the impression this was round 2 of the big joint venture arrow ballistic study performed by James Yates, Precision Cut Archery, Easton and a few others.
Yates in the backcountry has a video out about the upcoming study and mentioned a fair amount of groups and companies donated to fund the study. One name I remember hearing was Kifaru.

Yes there are just a ton of people with a crappy tune on their bow...... I was one of them until I decided to learn how to do it correctly

I was actually wondering about this the other day.

The question was, "I wonder if anyone has ever done a study identifying the ideal FOC for arrow flight/ trajectory as well as the terminal ballistics effects?"

I look forward to their results.

Good observation, I think you are right. For sure it made the 2025 study on Fletching easier to differentiate.

Easton was listed on the title of the vid- I don't know how much or how little they were involved.

QUESTION; I'm curious, How many bowhunters -that you know personally- don't tune their bows for perfect arrow flight? I know a lot of bowhunters and guys at our club...and I can't think of a single one.

 

[Beendare]

Results;

My bet; If you get too far over 10-15% FOC it destabilizes the arrow.

Your sample is flawed- you are only considering archers at your club! The ones who care and practice.

The majority are back yard shooters, bought the bow online, and borrowed arrows from a friend day before season! They probably aren’t your friends

The results will tell you which setup is more forgiving for a 1 inch tear in the direction they set it up. Anything beyond that will simply be inference and guessing, no different than now.

How do you know that?

I'm playing devils advocate, I would assume you are right...but thats why I phrased it as bowhunters you know. Thats accurate info- not guessing.

My premise is that a study like this will be ignored by the first time backyard shooter but relevant to the guy that works to improve on his form and setup. Those guys tune their bows.

It seems the study is working from the premise that there are a lot of guys that just screw on a BH and hunt- which could be the majority of guys- I don't know.

A one inch tear out of a machine is a one inch tear every time, with fixed broadheads probably an issue but with field points or low profile mechanical probably not.

your reasoning?

 

[Beendare]

your reasoning?

The evidence that very high FOC does anything to help is very thin and amounts to a bad longbow shooters casual observations. The margin of error on those observations is more than the claimed gain.

The Easton FOC range has been proven best from testing by the original rocket scientists as far back as the 1940's, Easton engineers and every pro in every archery discipline. There is not a single pro that shoots very high FOC- Zero. The guys that claim, "but thats target guys" aren't getting the relevant concept; it's more accurate...and accuracy is everything in bowhunting.
