Just picked up an old M-12 in 20 bore and there is a slight ring of rust in the chamber where the brass sits, not really bad but I think it grabs the spent hull sightly on ejection. Gun still cycles fine but dose not throw the spent hull as far as I think it should.
Other than wrapping a brush in steel wool and oil and working it with a drill is there a better way I can remove the rust?
