A shot gun shell is disclosed which employs a wad defining a shot cup, including closure means associated with the open end of the shot cup adapted to operate upon insertion of the wad into the shot gun shell casing to restrain the shot within the cup without the aid of external means. The wad of the present invention employs a one-piece construction and may be manufactured from a plastic material. A shot shell casing is also disclosed which employs a circumferential bead located about the inside surface of the casing adjacent its open end. The bead serves to frictionally retain the wad of the present invention upon its insertion into the casing.
