Hello. I know there's a similar thread, but i didn't want to derail it. I was watching a program about the Green Beret's on the Military Channel the other day, and they did the thing where they shoot a 9mm and a .45 caliber into clay to show the differences in pressure created by each round. That being said, with a standard 230 grain .45 a.c.p. round, what is the minimum sufficient velocity in order to cause this effect? They said it was at 800 fps, but they didn't say if it was ball, or hp or what. Does anyone know the specs of the military standards today and during the past? I was looking at some G21's, but the velocity was about 50-75 fps off of a fullsize 1911 (and STI was the one I had the spec's for) in spite of only a .4 inch barrel difference. If anyone could shed some light onto this, it would be greatly appreciated.
