all ammo is not created equal and dont be under the impression that after shots fired, the BG is going to run.
I met someone in a course in november that survived a home invasion a few months prior. He fired .45gap rounds at the BG that had just broken down the front door, he was waiting at the end of the hall, because the knocks were suspecious, and he didnt reconize them. Soon as the BG (and his 2 accomlices) opened the door, they saw him standing 15+ feet away, the BG ran at him. The good guy drawed and fired 6 rounds, all of which got caught up in the the jean jacket and sweater that the BG was wearing. Once face to face he he put the muzzle up against the BGs side, and fired one round through the torso. BG drops to the ground, and starts reaching for a weapon, good guy fires one through the guys neck. 2 other guys left the get away car running in the driveway.
So of 8 rounds fired, 6 got stuck in clothing. Needless to say, he did some ammo research after that
Rounds fired were Rangers if i recall correctly.
One of these days im going to do some of my own testing.
Story was verified by the instructor and another student in the class (both personal friends of the guy).
