Abstract
Gases of combustion vented from the bore of a shotgun barrel in spaced relation to the muzzle travel along one or more passageways externally of the barrel and are discharged externally of the barrel and ahead of the muzzle in a generally transverse direction relative to the barrel axis to create turbulence immediately forward of the muzzle and exert lateral forces on a shot charge after the charge leaves the muzzle whereby the short range shot pattern produced by the barrel is substantially enlarged. A finite, moveable mechanical obstruction projecting into the bore retards the advance of a wad to reduce influence of the wad on the shot charge.
