Abstract
A sabot for a shotgun shell provided with a recess in its base upon which opellant gases may act to radially expand and flatten the sabot thereby enhancing the dispersion of shot. In alternate embodiments the recess may be conoidal, parabolic, pyramidal, or an involute surface resembling a cone. The recess may also be comprised of multiple overlapping layers. Each recess provides a unique shot pattern for short-range antipersonnel engagements. In other embodiments, the foregoing recesses are provided with grooves to facilitate petalling of the recess and flattening of the sabot during and after launch. In another embodiment, the recess is filled with propellant and capped with a consumable plug to delay ignition of the propellant charge, further enhancing shot dispersion.
