shot about 600 rds of 22 LR rimfire thru my Ruger Mk II the other day, using LRN (lead, not copper plated), and while cleaning it, I noticed a portion of the barrel didn't let a cleaning patch slide down very easily, in fact it was quite hard. I brushed some of this stuff out, and it appeared to be slivers of lead, shaped like when you clip your fingernail. I eventually cleaned this all out. It appeared to be built up in the chamber or lead of the rifling.
I'd never seen this before. I've always shot jacketed centerfire, and this is my first experience shooting large qtys of full lead rounds thru a pistol.
Should I expect more of this crapola, or is something wrong with my gun ? If I shoot copper plated rimfire exclusively with this gun, will this problem recurr, other things being equal, assuming the bore is not damaged ?
Any advice or education appreciated.
