Abstract: An ammunition round for simultaneously launching multiple penetrators enclosed with a single composite sabot, without any nesting or physical contact between the penetrators. The composite sabot has petals which are engraved by the tube's rifling during launch to rotate the petals, without presence of a separate rotating band element. The petals are separated from the penetrator elements upon exit from the gun tube solely by centrifugal forces acting on the petals.

Abstract: A multi-piece projectile for a small arm training ammunition round maintains stable flight until reaching transonic speeds. During transonic and subsonic flight, aerodynamic features located on the projectile generate a pressure differential to increase limit cycle motion of the projectile. The aerodynamic features are located on a portion of the projectile which does not interface with rifling elements of the gun barrel and may include protrusions in or extrusions from the projectile.
