In an ammunition round a substantially full bore diameter bullet has a plurality of elongate grooves either helically formed or parallel with the longitudinal axis of the bullet and a sabot which has a body and fingers which engage with the grooves and seal the bullet in a casing, the sabot having a slightly larger diameter than the bullet so that the sabot is engraved by the refling slots in the barrel through which the round is to be fired, in order to rotate the bullet. In alternative constructions the grooves contain elongate elements or a plurality of spherical elements to prevent the conically tapered slug or bullet from tilting or cocking in the barrel after firing.
