I bought a Lyman Great Plains Rifle from a local pawn shop a month or so ago. Today I used my new bore scope and was shocked to see brow/rust colored dots in the bore a few inches in front of where the powder sits when loaded. My fear is these are rust pitting. Can anyone give any insight on what I'm actually looking at and if there is anything I can do to stop the progression? If it's a total loss, then what are my options? Can I sleeve the barrel for a smaller caliber or bore it out and get it rifled for a larger caliber?
