Wanting to learn what happened. Just loaded my first 50 rds .45 ACP after trying 3 mags of different charges, so a total of 78 rounds. Had one misfire. I think I might have missed the powder charge. The barrel was clear but action didn't cycle. Is just a primer enough to push a slug out of the barrel. Shooting a Para GI Expert 5" barrel, using winchester 230gr JRN and 5.0 grains of Win231 with CCI primers. If I made a mistake I guess I went the right way with no charge vs a double charge. Maybe I'm not smart enough to do this?
