I have an old Miroku that has a bit of pitting in the chambers, i believe this can be re-lined with chrome linings has anybody had this done and the cost involved and possibly recommend someone.
I'd wonder about the necessity if there were no problems with extraction, which would require some REALLY deep pits. I've seen some pretty nasty pits in rifles as well as shotguns and clean seemed way more important than the pits. I mean, wire brush it clean oil it up and move on.
