I purchased some new 223 LC annealed brass about a month ago. I formed it to 20 Vartarg without any issues. Since the brass was new, I didn't have to remove the crimp from the primer pocket. When I started priming, I noticed how easy the primers went in the pocket. A little to easy. I use the Century 21 priming tool and can easily feel the seating of the primer. Just as I finished the seating a bullet, the primer fell out of the pocket. Continuing on, one more primer fell out. I only loaded up 30 rounds for this session, but have not tried them out yet. Anyone else have/had this issue? Suggestions welcomed.
