Twix, the reason for the AR in 45ACP was the purchase price $500 for the upper and lower. I plan to get an upper in 10mm. The match went well for 2 stages. The 1911 had a case head seperation, left about 3/4 of the case in the chamber. I was using new Win brass, Win primer, 12.4 of AA7, with a west coast 155 plated bullet. Until the 1911 failed I was having a good time, next month I will be using my beretta 92FS, it's never failed me in 6K rounds.
