I use a .62 caliber smoothbore percussion lock rifle made by Green Mountain Barrel Co. I load 80 grains of Goex 2f, then a over the powder wad. After that I use a fiber wad and on that load 100 grains of #6 shot. After that I use two over the shot cards. This is a good combination to 25 yards for me. Although the turkey would not cooperate the first time out and then due to a illness, I missed the last season...
