I’ve read a few threads about similar issues, but unclear on how to correct it with a mag lip tool. First PRS match this weekend as well. I have a few mags that do not push the cartridge against the feed lips. The head case side is lower, so the bolt can’t catch it. I’ve tried cleaning it out, dry lube, and carefully stretching the spring. These are almost new mags and have seen only a handful of trips. I have one Gray Ops mag that feed w/o issue. 6GT, Solus action, MPA Vanquish chassis, factory 108 ELDMs. Any advice appreciated before I tweak lips.
