Abstract
A projectile in the form of a sabot shotgun slug assembly includes a cylindrical slug, a cylindrical sabot positioned about the slug and a pressure wad co-acting with the slug and the sabot. The cylindrical slug defines a central bore extending partially therethrough. The slug is preferably made of a deformable metal. The sabot defines a plurality of longitudinally extending internal grooves. The pressure wad has two ends, with a gas seal located at a first end and a post located at a second end. The pressure wad further includes shock-absorbing members formed between the gas seal and the post. The post is positioned within the central bore defined by the slug. In operation, after the sabot shotgun slug assembly is fired, the slug deforms and expands outward to fill the plurality of grooves defined in the sabot which mechanically locks the slug and sabot together to stop any slipping movement of the slug when torque is transferred to the slug through the sabot due to the twist of the rifling and, simultaneously, expands inward to engage the post such that the slug, the sabot and the pressure wad remain connected together while travelling downrange toward a target.
