I have a TC 56 smoothbore that I have been playing around with and can't seem to find a single repectable load. I have been using .530 and .535 balls I had on hand and a variety of patch thicknesses and powder charges. I was thinking of getting some .550 balls and trying those. Anybody have some kind of working load that I can use as a starting point? I need to do better than the shotgun patterns that I am getting now. Maybe I am just doing something wrong though too. This is my first experience with a smoothbore and I have treated it like I would any of my other rifles with a PRB.
