Did the 'smith say how the bore looks? If the bore looks acceptable and it's confined to the chamber, you might be able to get acceptable results with some work on your own. Or not. Hard to say in advance.
Did your local 'smith that looked at it do the barrel work originally?
Good shootin' -Al
^^^^I would try throwing $50 at a flexhone and lightly polishing the chamber before junking the rifle. Unless you really want to rebarrel it.
