Thread: Bore Rust?

Ideally, the bore should be smooth and shiny and the rifling edges square and sharp. If you have a chance to compare yours with a new barrel I think you will see the difference. I would suggest an immediate "deep clean" starting with carbon remover and a cloth patch followed by copper solvent and a bronze brush. I think you could expect to take a good half hour of repeated cleaning before you know if there is any irreparable damage to the bore. Then again, at the end of the day, if it shots to your satisfaction don't worry about it.
