ABSTRACT:
A spherical convex pusher plate member is positioned intermediate the rear end of a subcaliber tubular projectile and the forward section of a cup shaped sabot carrier to improve the ballistic performance of the projectile by reduction of a parasitic weight and faster separation of the carrier after launch. Propellant gas pressures acting on the convex spherical section of the pusher plate causes deflection thereof sufficient to force the sabot to loosen from the projectile to provide an improvement in projectile velocity.
