Was out with my brother this afternoon. Shooting his armalite dmr local 500yard range and had some new handloads cause huge issue. Had some berger 175gr otm pop out of seating depth and lock up the mag. I'm at a loss how do I correct the issue can I just crimp on the vld or do I need to buy a canalure machine and if I canalure how much will it screw with my bolt gun and charts?
