I'm having a feeding issue where about 20 percent of the time, the round will get jammed about three quarter of the way into the barrel. It looks like round is not lined up with the bolt and the rim of the cartridge is slightly high(round is slightly pointed down as it enters the barrel). If I back out the bolt slightly, the rim of the cartridge falls down and aligns itself and it goes in. Any ideas how to remedy this? I can post a picture, if you guys have no clue what I'm talking about.
