I inherited this gun from a friend's estate. I'm not a black-powder shooter & have no interest in it so I'd like to sell it. I think the original kit came with 50 round ball of which it looks like half are gone. Makes me think it was shot perhaps 25-30 times. There is also a pound of Pyrodex with it which still feels full enforcing my 30 round theory. It's been oiled & nicely cared for. I don't think it has ever been fired with BP. There are a few extras like patch grease, powder charger, capping gadget, powder measure, tin of caps & some wads. I realize I can't ship the Pyrodex. What should I sell this for?
