I joined the forum last season as some were discussing the doe I shot at 338 yards last year. I wish I could show the bullet to demonstrate how much energy was left for expansion, but darned if I wasn't still getting a pass-thru at that range (no shoulder though). She was DRT.

I believe in real life over calculations, but the calculations have me sufficiently skeptical that I am unlikely to try anything further!

The calculations also say my .40SW Glock is way below the limit, but I have finished numerous deer with it and it has yet not to pass thru with hollowpoints. Even my cap-and-ball will go through, but like the Glock there is no shock damage. If we're talking the same 800 ft lb figure I've heard thrown around, I do believe that it takes about that to get real shock transfer on a game animal. However you will still get a wound channel with less than that, and we all know what an arrow can do with a wound channel. A .40cal hole through the lungs is quickly lethal.
