Definitions

  • the present invention relates to ammunition and particularly to ammunition for use in conventional small arms weapons having rifled or non-rifled barrels.
  • Our EP-A-0129777 describes an ammunition round which comprises a casing for containing a propelling charge, a substantially full bore diameter bullet which has a plurality of full length grooves in its outer surface extending helically around or substantially parallel to the longitudinal axis of the bullet, and a sabot in which the bullet seats and which seals the bullet into the casing, the sabot having at least a part with a diameter greater than the diameter of the bullet and a plurality of fingers engaging respective ones of the grooves in the bullet to cause the bullet to spin as the sabot is rotated by engagement with rifling grooves in a barrel through which the round is fired.
  • a similar ammunition round for non-rifled barrels is also disclosed.
  • the bullet or slug has a rearwardly tapered conical protrusion and the sabot has a complementary conically tapered recess, the conical angle of the recess in the sabot being greater than the conical angle of the protrusion on the bullet or slug.
  • the bullet and slug are of the type referred to in EP-A-0129777, in which the bullet has helical or parallel grooves which are engaged by fingers on the sabot in order to transfer spin from the sabot to the bullet mechanically, but the invention has application to prior, conventional bullet and sabot configurations.
  • the bullet or slug 1 is preferably of the type shown in Figures 1 to 5, or 6 to 7, or 12 in EP-A-0129777.
  • the bullet or slug 1 is suitably modified to include a rearward protrusion 2 having a rearward conical taper of conical angle ⁇ , thus providing a conical surface 3.
  • the sabot 4 which is preferably plastics, has a complementary conical recess 5, the conical surface 6 of which has a conical angle ⁇ greater than the angle ⁇ of the taper on the protrusion 2.
  • the sabot preferably has forwardly projecting fingers 7 which engage in grooves (not shown) in the bullet 1, as described in our EP-A-0129777.
  • the conical angle on the protrusion is 55° and that on the sabot is 60°.
  • the sabot 4 has a central aperture 8 which allows forward movement of the sabot (see Figure 2) on filing of the round under the gas pressure acting on the rear face 9 of the sabot. Due to the different conical angles on the sabot recess and bullet protrusion a substantially uniform expansion 11 of the sabot over the length of its cylindrical periphery 10 is produced on firing as shown in Figure 2 as the sabot is compressed against the rear of the bullet.
