I’ve been reloading for my L-frame
.357 for quite some time. Recently I’ve encountered a problem I’m having trouble diagnosing. The cases are all nickel plated Starline brass. The primers are all CCI small magnum rifle primers.
The primers are seated into the case primer pocket so as to be flush with the case head.
When I try to shoot these cartridges, about 2/3s of the rounds fail to fire. When I examine one of these failed-to-fire cartridges, I notice an light strike on the primer. The rounds that did fire have a much deeper strike. None of which is surprising.
BUT, both rounds have their primers set equally deep into the case pocket. I can’t see anything that would explain why one cartridge primer has a deep strike and the other a shallow, light strike?
Any ideas?
