I have no idea how to load a choked shotgun. I have a .62 caliber Green Mountain Barrel Co. Smoothbore. All I do is drop the powder down (80 grains of 2f) then an over the powder card, then the fiber wad, the shot in a homemade paper wad, and finally two over the shot cards. Out to about 25 yards I get good patterns. I wish I could stretch that a little but am new to smoothbores and have no idea what more I can do...

Good luck with your shotgun. It should be an interesting turkey season..
