I knew of a copper whom did the reloading for his PD for practicing. He was taking the loaded 556 rounds and dripping crazy glue on th eprimers to keep them in place on the worn out brass. I told him he was a nutjob and asking to get one of his buddies hurt , let alone wreck a rifle. The second I feel a primer go 'swoosh' with no resistance I set it aside and later retrieve primer and it is SCRAPPED , No exceptions.
