I have been wanting to get a black powder shotgun for some time now. About the only one I can find is the Pedersoli. I want one that (for lack of a better way of explaining it) "looks like a real muzzle loader".

First question - Are there any other guns out there besides the Pedersoli?

Second question - Should I get a 12 or 10 gauge? And why?(I will start hunting for turkeys and doves but will move to ducks and geese real quick I think)
