In sorting though brass I pick up at the range I occasionally find empty brass with unfired primers. I just sorted a batch of 250 9mm cases and found six that had unfired primers. There was no mark where the primer had been hit with a firing pin. I've been tossing them out, but it occurs to me that I might miss one some day and wonder if there is any danger in depriming them? I also find some unfired rounds that have a firing pin strike on the primer and I've been tossing them out also. Would it be safe to pull the bullet and save it?
