Shot 7 1/2 or smaller. Shotgun loads are basically the same as SASS. We shoot some knock downs and some swingers, range is normally 15 yards or longer.
If you decide to shoot in the Originals Class, all are currently shooting a revolver and a rifle. You can shoot any two guns, but I have never seen anybody shoot a shotgun. Proposed bylaw change up to make the class 1 revolver and 1 rifle.
Good way to start. Some of us have returned to the single rifle and pistol. Which ever class you choose it is the most fun you can have with your clothes on.
