Hey, Weshoot, you're never going to win this argument; I gave up long ago. Even though you are, of course, correct.
I once had a fellow on a forum counter my comments about energy being the principal factor in anti-personnel with the comment that: "well, then why don't you hunt moose with your 17HMR". So I calmly answered him that it is ENERGY, not velocity that counts, and that if it were just 'caliber' then why are almost all white tails taken with 30 caliber guns, instead of 45 ACP's?
Most will also keep repeating the mantra about bullet size, completely forgetting that a smaller bullet going faster will EXPAND, often to MUCH larger size than that slow big bullet.
So it's not worth the effort to try to discuss this anymore - for me anyway. I just read several comments in a handgun magazine that once again referred to "stopping power" and "knockdown power" of a 45. Oh well..... (BTW, I also read where a LEO was called to eliminate a rabid fox, and it took MULTIPLE SHOTS with a 45 ACP to kill the little thing....)
