Hi long time lurker first time poster, I recently purchased a Winchester 1885 in 32-40. It had the barrel relined and looks like a professional job. Upon trying to chamber a round they fit really tight and didn't want to extract. I coated the cartridge with Dykem and when a shell was chambered and knocked out of the chamber it has a bright ring 1/4 inch from the rim. The Dykem left a corresponding ring in the chamber. The ridge is maybe a few thou. high. It's like who ever chambered the rifle had a chip in their reamer. Can I lap that out with an abrasive (like valve compound) coated empty casing (cut off just past the ridge so I won't mess with the rest of the chamber) or do I have to rent a reamer?
