A lousy 60 caliber? How much does the hallowed .223 expand to? I've never seen a **** wearing a shirt and jacket, so can't comment on the performance of the .45 ACP against one, but my 230 grain +P+ handloads don't leave much ****.expanding to more than a lousy .60 calibler in animals, where a shirt and jacket are put into the bullet's path (as they always are when you have to shoot a man).
I'm assuming that when you refer to "ball", you really mean a full jacket bullet. (That isn't what it means, but common usage has bastardized the meaning). Why would someone limit themselves to a full-jacket bullet in a defensive load? My 230 grain loads, either XTP's or Gold Dots would be my choice. Since your doomsday has not yet arrived, I think toting a rifle around the streets for self-defense would tend to make people a bit twitchy, and probably land you back in prison.
The .45 ACP isn't my favorite gun for SD, the .45 Colt is, but don't dismiss the ACP as pretty much useless. When you do that, you show a total disconnect from reality.
