Not sure where to post this, but since it is primarily a 1911/.45 questions, thought I would try it here. A question of theory: So everyone knows the history of the .45 ACP being a genuine bad guy stopper. History has proven it with years of military service. Some of you out there have had hands on experience with this. My question: All of that history is based on ball ammo, military issue correct? So, did the military use jacketed 230 g or unjacketed lead? Does that change things signifigantly? If the standard is FMJ, then ANY name brand JHP in a 230 .45 should be outstanding yes? Now I know, there is always good, better, best. But if the .45 'hardball' does the job so well, then should one pay the ridiculous prices of the super ammo that is out there? Example: Rem GS +P...$38 / 20 rnds vs. Win 230 JHP...$31/50 rnds. Also, does the FMJ tend to overpenatrate in a HD situation? My primary HD bedside gun is a .40 loaded with 165 JHPs, but I'm starting to keep the 45 around as a secondary. ie, working in the garage in the evenings etc.
