That old high grade Fox, cased & never fired,, I wouldn't fire it. I don't really collect either. So why drasticaly devalue the gun by shooting it,,just to say you did so.
Works for some I guess,,really makes no difference to me.
I'd let it be,,safe in it's still unfired condition,,and let someone else who desires to fire it pay top dollar for it, just so they can be the first to shoot it..
...And that's fine,,it's their gun at that point.
The boys at Pawn Stars would need to fire it for sure.
Others I just use carefully.
I don't treat them as survival guns needing to perform in every imaginable climate or condition.
They're old(er) like most of us and need or at least deserve a bit of extra care I think.
