I have some 10 round and 8 round power mags that I use in my S&W 1911. I reload semi-wadcutters and have no issues with the 10 round mags, but when I use the 8 round mags I get some failures to go into battery. I was able to mark a couple of rounds with a marker to identify the location of the problem. It seems they are getting caught at around the ten o'clock position while entering the chamber and the case at ten o'clock is getting peeled back 1/8 th inch causing it no to chamber. It hapens a various times not on any specific round count. Is it just me or does anyone have similar issues?
