Thanks for the info about amount of shooting- if I  understand correctly, the prior owner likely used rifle primers (no damage noted), and in the span of less than 2G of pistol primers, it showed obvious damage. That sure is quick enough to be a real worry. I did a hundred or so in my rifle, and there was no change in it's shooting, so I stopped- no damage either. But, I'd heard the warnings here and there. I opted for the 'err on the safe side' approach. I also had some notion that the pistol primers had a small possibility of not being seated to the same depth all the time, and that might cause small changes in ignition- don't know if that's real or just a dreamt up problem. Anyhow, I'm glad you got 'er fixed and it continues- it does, doesn't it?
