RE: Heavy arrow, more KE....light arrow, more speed..??
It is clear, buckeye, that you do not comprehend the physics of the heavy arrow vs the light arrow, when it comes to penetration.
Second of all ...... prove me wrong?..... what did I say that was wrong?
Sacrificing KE for speed is wrong. There is also something called real world experience that proves to be different from numbers on paper. This is the physics part. With all of the variables. I don't think that my experiences are different than what has been published. I've shot deer with light fast arrows, until I ran into a performance issue. I started using a heavier arrow, without changing poundage, and the issue went away. Especially, if you are shooting a lighter poundage bow, 60 lbs. or less, you are better off with the advantages of the heavier arrow. How's this, It's sort of like using a .243 or a 12 ga. slug at 50 yards. They both should work, but I'd take the 12 ga.
I kind of figured you were related to Atlas.
