Abstract
A device for controlling the scatter of shot wherein the barrel of the shotgun adjacent the muzzle is provided with grooves disposed at a small angle to the longitudinal axis of the barrel. The grooved portion of the muzzle is constricted to provide a converging then diverging wall portion. The roots of the grooves define a cylinder having a diameter comparable to the diameter of the barrel. The width of the grooves is greater than the size of the shot and discharge of the shot through the barrel past the grooves produces a twisting movement which provides an uniform distribution of the shot.
Claims14
A device for increasing and standardizing the scatter of shot pellets discharged from the muzzle of a shotgun barrel having at its breech end a substantially cylindrical contour, comprising converging interior wall means adjacent the muzzle of the gun barrel, a number of grooves in said wall means set at a small angle relative to the geometric axis of the barrel, characterized in that the bottoms of the grooves are on a circle coaxial with and conforming to said cylindrical contour, and the depth of said grooves is greater than the radius of said shot pellets.
