In my opinion, your gun does not need a refinish. It is a .338 hunting gun and as such, it is going to pick up some beauty marks. If it were mine I would leave it just as it is and appreciate it for what it can do. If you have any really deep scratches on it, just rub on a light coat of good stock oil. You should be putting on a coat a year anyway just to help keep it water proof and looking good.
Very nice gun by the way, I would be proud to own that one! Bob
