I ordered that gun from my dealer sight unseen, and when I first looked at it it appeared to have been used, it had that dark sooty look, the dealer said that was normal, so I took it. When I got it home and cleaned it, I was getting long lead shard out of the bore, like tinsel. Then I saw the nasty scrapes on top of the lands. It looked like some tool had broken or gotten loose in the bore during the rifling process. Took it back to my dealer and he sent it back. The new barrel looked much better, the top of the lands were smooth anyway, but it still leaded.
I've been trying to talk 3leggedturtle into using the fire lapping ammo. If ever a rimfire needed it, it was that one. It might even smooth up the chambers a little.
I've never had good luck with rimfire revolvers. I need to just stick with my Mark II.
