I'm loading 223 with CCI SR primers. I loaded 250 rounds yesterday and had some trouble with 43 cases where the primer would not seat in the pocket. They would not go into the pocket with even with considerable force. I destroyed two of them (they didn't go bang, just crushed them). The brass is mixed head stamp I picked up at a range and it's been processed (washed, cleaned, polished, mouth resized, trimmed to length, deburred and camphered). In addition, all were checked for military crimp and the few I found were reamed. When I process, I'm finding 10-20 cases per 200 or so cases that have military crimp, so the fact that I found 43 in 293 is too many.
Most of the brass that would not accept the primer had military crimps but the reamer tool and the pocket cleaner (Lyman) fit inside all of them. For now I set these casing aside and moved on to others. It just seems that the pocket hole is too small for the primer.
In addition, I found that once I attempt to seat a primer in a case with a small pocket, that primer would be difficult to seat in other cases, as if it were slightly flattened.
Is there some trick to getting the primers to seat? Is this a known issue with CCI primers? Should I seat the primers using a different tool? I'm using a Classic Lee turret.
Thanks in advance
