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.
