Recommended I ask this here after raising the issue in the 45 room. I roll my own ammo for my 45 tac. Because the Ranier 200 grain flat points were the only thing available for awhile at Midway that's what I got. Shot about 50 of them the other day and one out of each mag wouldn't feed and it was always a few rounds into the mag. Prior to this I have been shooting Hornady and Ranier HP's without even so much as a hint of a hiccup. Same with my mags ... all have worked great until this past weekend with the FP's. It was recommended I polish the feed ramp. Is this above and beyond cleaning it well? Advice please! BTW, my ammo is a 200 gr FP on 5.3 grains of Titegroup and an OAL of 1.225. Any thoughts on the why's of the problem?
