:thumbsup: I picked up a 56 caliber smoothbore barrel for my T/C White Mountain carbine. Fit perfectly.
Fired the barrel last weekend with both shot and roundball. The shot load I settled on for the time being is 70 grs. of Goex 3F Pinnacle, over powder wad, a lubed wad, #5 shot with an overshot card. It patterned very well and much better than the two loads I had earlier tried.
Shot four roundball loads down the barrel. I used .535 rb's with 70 grs. 3F Goex Pinnacle with an over powder card, next the roundball with a .018 lubed patch. That load shot printed left and approx 1.5" high. The next load I used for three shots the .535 roundball with 70 grs. 3F Pinnacle and a .015 lubed patch, Elevation of shots were very close and printed approx. .75"high. If I can get this rifle/smoothbore centerd I plan on taking it Turkey hunting next week. Two weeks after that modern season for whitetail season opens. Will either use the .56 smoothbore for Deer or go back to my old standby which is a lot lighter. A Thompson Center Seneca in .45, it's my favorite muzzleloader. Good luck to you all.
