  • Patent number: 7451705
    Abstract: This present invention relates to a non-discarding sabot projectile system. One embodiment of the present invention relates to coupling the sabot to the core at one or both of an upper sidewall region and a bottom region. The upper sidewall coupling between the sabot and the core utilizes a keyed groove system in which the sabot is hooked into a recess on the core. The bottom coupling between the sabot and the core utilizes a lower member that extends below the core and through the sabot. The lower member is configured to be punched to expand into the sabot. In addition, a cup member is disposed on the sabot below the core. The cup member scrapes carbon material off of the inside of the gun barrel as the system is loaded. In addition, the cup member minimizes fouling and improves accuracy by providing an additional seal between the sabot and the barrel during operation.

  • Patent number: 6186071
    Abstract: A projectile includes a core having a substantially conical head extending from a tip to an outwardly projecting annular lip. A substantially cylindrical body projects from the conical head adjacent to the annular lip and extends to a substantially flat tail end face. An annular slot is bounded between the annular lip and the cylindrical body. An annular groove encircles the body between the conical head and the tail end face. A plastic sabot has a front end with a chamber recessed therein. The chamber is bounded by an inner side surface having a substantially dome shaped annular bulge radially inwardly projecting therefrom. The body of the core is received within the chamber of the sabot such that the front end of the sabot is received within the annular slot on the core and the bulge on the sabot is received within the groove on the core. In another embodiment, a plurality of spaced apart fins inwardly project from the inner side surface of the sabot.
