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.
