Having 5 or 6 shots in a revolver is nice, but the caps causing issues and the time it takes to load them is losing its appeal. So, I have been thinking it may be time to get a single shot or a double barrel muzzleloader, but I'm not sure what to get. What I do know is I don't want a flintlock and it must be at least .36 caliber. Also, if it can use .375 or .454 round balls that would be a big plus. No preference for it to be rifled or smoothbore, the distances I'll be shooting at with it (25 yards max) either would work. Things that immediately come to mind are the Pedersoli Howdah and the American Guncraft Diablo. Lyman has their GPP, but that is rather large for a single shot. Also, I have long had an interest in the Great Gun derringers from Czech Republic and would pay to have one imported. Thoughts?
