Definitive arrow study- Easton

[BBob]

your reasoning?

Beyond a certain point in real-world conditions, particularly in wind, the steering influence of the broadhead outweighs the vanes’ ability to stabilize flight with too much FOC. And what he said above ^^^

Edit: I added "with too much FOC" to the above to further clarify my thoughts.

Back in the day when I shot a ton and experimented a ton I kept records of how and what I shot day in day out and figured out what worked for me. "High" FOC wasn't it, at least for me.

So many very good bowhunters and shooters I know have said the same.....

How? A BH has less surface area than the fetching and with high FOC it has a way shorter lever with which to impart any lateral force than the fetching does.

I do agree that very high FOC arrows can be effected by crosswinds more meaning they fly more sideways

Just figured what you were eluding too, I think. You mean in a cross wind the high FOC arrow can tail out which points the BH to the opposite side which induces steering. ??

My argument was in still conditions the fletching will have far more influence than the BH

@ozyclint, the you start referring to terms like lever arm...we know who you have been listening to for arrow advice. Grin

My bet is this study blows those old EFOC theories out of the water.

The fletch part of the study gives us a clue; Essentially, we need enough fletch....and more is not better. In a cross wind, too much fletch acts much like putting your BH too far forward or extra weight on the tip- a lot more pressure on the rear portion of the arrow pushing more arrow sideways.

What Easton and all the pros have figured out- a little bit of FOC is a good thing for best arrow flight and accuracy....plus its better on the launch and the best in cross wind performance.

Be careful where you get your arrow advice. The claims of better penetration for high FOC have never been scientifically proven. We have known since the 1940's, an arrow with an FOC of 10-12% flys further which indicates the best possible performance. Adding more arrow weight WILL give you better penetration- the heavier arrow absorbs more of the bows energy. Penetration is non issue with most bows that have energy to burn....and is more of a function of BH efficiency than arrow factors.

I don't really care how far an arrow flies. It not an indicator of performance to me. It's only got to travel 15m before it has to go through a water buffalo. Getting through the water buffalo is the important bit to me.

The video is well named....a ballistic study.
They've conducted tests from bow to target with scrutiny on arrow flight and accuracy.

Does know one care about terminal ballistics? How the arrow reacts when encountering different forms of resistance.
