Cougar has found a tried and true method for penetration.Get a PROPER SPINED arrow,balance it out and make sure the aluminum is of a thick walled variety and penetration will be awesome.The most important thing he is doing is shooting arrows that are matched to his setup and balanced right.
Don't give me credit for anything, I switched from using 2216s to 2213's for 3D shooting several years ago specifically to gain speed on the course. I made the mistake of using them for hunting, and although I killed my share of deer with them, I noticed a loss of penetration on non-passthroughs and this was using the same broadhead. Only reason I don't or haven't gone back to aluminums is I've been shooting carbons for 4 seasons and although I believe the smaller diameter carbon arrows do improve penetration, I also believe in the heavier carbons for hunting. I am also stubborn.[8D] Thats why I am currently considering the Beman Max-4 camo arrows.....small diameter, heavier weight and advertised straightness of .003. I wish they used a uni-bushing with the ACC nocks AND I wish someone here would do a spine degradtion test on them.
