Oh keith44...that is so awesome that you've started this thread. Smooth Bores are a hoot.
I got my first smoothbore (10 gauge double by Pietta) to hunt geese. It was such a fun way to hunt, and after a season or two I got very profficient at loading and shooting between flocks.
My next was a sweet little upland 12 gauge double made by Pedersoli. Its bore is under sized so I load it with 13 gauge wads. Doves, Pheasants, Rabbits and Squirrels have been its main quarry.
About 10 years ago I got the Flint Itch and got a Brown Bess Carbine Kit from Dixie Gunworks. That became my new go-to gun when it can to using a blackpowder smooth bore. It ALWAYS went off, and uts taken geese, ducks, doves, rabbits....squirrels...I'm sure that I'm missing something.
At the moment I have a smooth bore on order at TVM. Its a 20 gauge flint...I can't wait till it arrives.
I just recently acquired round ball molds for both the Bess (.75 calibre) and the TVM smooth bore (.62 calibre). So I have little to no real experience at the range or hunting with projectiles out of the smooth bore. That'll change in a year or so...
You get yourself a smooth bore there kieth44 and it'll be a blast...literally and figuratively.
