RE: Does Kinetic Energy = Penetration?
"The minimums that AMO suggest are still much higher in weight than a lot of the carbons will provide so that is why I say they are still moderate weights and not minimums."
I'm glad to see you disagree about what's minimum and moderate with the industry trade board as well. I was starting to feel a little picked on. <img src=icon_smile_big.gif border=0 align=middle>
However, I must point out that the minimums are based on how much weight it takes to prevent damaging bows or reducing their useful lifespan, not on arrow materials. And certainly, there has to be a little fudge factor thrown in to please the corporate liability lawyers. But I know I wouldn't want to be standing on the shooting line next to someone that was shooting lighter than AMO minimum. Been there and done that in the 80's. Got the scars to prove it.
Light carbons will indeed outperform light aluminum. No question about that. When light aluminums start bending and collapsing due to their inherent weakness, it uses up energy that a stronger, thick walled aluminum or carbon put into penetration.
However, I remain a devoted fan of Elmer Kieth and Fred Bear, firmly in the momentum camp.
