good evening friends
i just recovered a lot of firearms from a deceased estate including a very nice old stevens shotgun, so old in fact that it is a "J Steven Arm & Tool co" apparently from 1880 or thereabouts, very nice toy.
Now a few of the shotguns i got have got a little surface rusting on the outside of the barrel and a little in the bore which i dont think is critical but it is making shell insertion sticky, which as i have experienced in the past will make removing them after firing damn near impossible.
is there a purpose made tool, maybe a steel brush or some kind of grinder head I can use to rout the chamber smooth? I've got a plastic 12 ga cleaning brush but its not cutting it, hence steel or something.
