Re: .45 bullet weight
I shoot 200gr hard cast LSWC in competition. I have some 230gr ball hard cast lead, some 230gr FMJ and some 230gr XTPs. I would not hesitate to use any of them. Even the match loads would stop a fight. I know there are a lot of gee whiz bullets out there, but I haven't ran into anyone willing to stand downrange and catch one of my match bullets.
Honestly, a hard cast lead bullet is what a lot of people use to hunt with, so they wouldn't be too bad for defense as long as they aren't run too hot.
Even if they don't expand, remember, a .45 will never shrink. You are still putting a near half inch hole in something. I figure if nothing else my match loads will help me with shot placement. They are dead nuts accurate.
