ABSTRACT:
A shotgun shell includes a sabot with a tubular portion extending from a e, a chamber disposed within the tubular portion in communication with an opening in the base, a load of shot disposed within the tubular portion around the chamber, and a valve disposed between the chamber and the opening to control the flow of propellant gases into and out of the chamber. The valve can be a choke with a flow constricting orifice that delays pressurization and depressurization of the chamber. Alternatively, or in addition to a choke valve, a movable valve member can be disposed between the chamber and the opening to seal with a valve seat in order to capture high pressure propellant gases which, upon emergence of the sabot from the gun barrel, will assist in creating a highly dispersed shot pattern at close range. Also disclosed are a number of ways in which the sabot can be modified to control the stiffness of the tubular portion in order to change the shape of the shot pattern to suit specific applications.
