I just acquired an old 625 model of 1988. I'm experiencing an issue with .45acp ammunition. I've tried a couple brands. Both have the same issue. I can't get through a whole cylinder before one of the primers backs out and binds the cylinder. I got 100 rounds of. 45 auto rim with the gun, and they don't have that problem.
There are countless numbers of these guns in use, and I don't see any complaints about this problem. As a matter of fact, several shooters use them in local matches without issue, so I know it's not an inherent problem.
The question is, why is it happening? Could it be that the moon clips I'm using aren't thick enough, and they're leaving too much room behind the case head? Is my ammo too hot? Not hot enough?
Has anybody else experienced this? If so, how did you solve it?
