I loaded up about 100 .458 SOCOMs (all stuff from here) took my rifle to the range and the rounds wont strip from the mag and chamber all the way. Now if I take a single round and drop it into the chamber, it falls right in. If I double charge the rifle it will finally seat into the chamber from the mag. I was thinking I need either a stronger buffer spring, or heavier buffer. Ideas, or something I might be overlooking? And dont say lube!
