No sir, Blackey Cole is correct about the shotgun. Split Rail who is a National and World Champion Frontiersman uses a hammerless shotgun!
FRONTIERSMAN Any Main Match percussion revolver with non-adjustable sights (Note exceptions listed re: dovetailed sights). (Exception: The 1873 Uberti percussion revolver is not allowed.) Revolvers must be shot duelist or double duelist style. See Duelist description for required shooting technique. Must use blackpowder in all loads (rifle, revolver, and shotgun). Must use a side-by-side, single shot, or lever action shotgun in the main match stages. Any SASS–legal pistol caliber rifle is acceptable.
