Definitions

  • the present invention relates to ammunition and is particularly useful in ammunition for use in conventional small arms weapons having non- rifled barrels.
  • Conventional slugs or bullets usually have a lead core with a surrounding copper jacket of a diameter which is slightly oversize with regard to the diameter of the barrel of the weapon with which it is intended to be used, the copper jacket of the bullet being engraved during its passage down the barrel of the weapon by the helical rifling grooves in the barrel.
  • the bullet is spun by the rifling grooves to stabilize its flight, but a considerable proportion of the energy from the ignition of the cartridge containing the bullet is lost through friction between the bullet and the rifle barrel caused by the engraving of the bullet, the friction generating heat in the barrel.
  • heat generated by the friction of the bullets passing through the barrel can be a serious problem, causing the weapon to jam and firing to stop and, at its worst the barrel to bulge or burst.
  • a conventional shotgun slug is a hollow, cylindrical lead cup with a domed end (ogival shape), but as a shotgun has no rifling grooves the slug does not spin and is accurate only up to a range of about 100 metres or even less, partly due to the lack of spin and partly due to its unstream- lined shape which slows it quickly.
  • DE-C-583098 discloses, according to the preamble of claim 1, a slug or bullet which has a star- shaped rear portion which is attached to the ogival front portion of the slug and which has a plurality of V-shaped grooves.
  • the grooves are located tubular elongate elements.
  • the tubular elements significantly increase the overall diameter of the composite projectile, causing the slug to be undersized.
  • the elements are secondary projectiles and extend longitudinally only over the length of the rear attachment portion.
  • FR-A-1124740 discloses a shotgun slug with plural secondary projectiles in the form of spherical pellets which are housed in U-shaped grooves formed in the sides of a round-nosed, parallel- sided slug.
  • the secondary projectiles can be located in a hollowed out portion of the slug.
  • an ammunition round comprises a casing for containing a propelling charge, a substantially full bore slug of ogival shape and a plurality of elongate elements preventing the slug from tilting off axis as it travels down a barrel, characterized in that the slug has a plurality of grooves in its outer surface extending substantially along the longitudinal axis of the slug, the elongate elements being seated in the grooves and having a dimension substantially the same as the radial depth of the grooves and extending substantially the length of the slug.
  • each groove has a substantially V-shaped cross section and the slug is made of steel.
  • the elongate elements are made of steel. By forming grooves in the surface of the bullet the bullet can be spin and/or fin stabilized during its passage through the air.
  • the slug and elements are formed of steel.
  • the slug 1 When seen in elevation as in Figure 2b, the slug 1 has a conventional outline having a parallel sided portion 2 and a tapered nose 3.
  • the surface of the slug is not a smooth cylindrical/tapered surface, but rather a plurality of V-shaped grooves 4 are formed extending parallel to the longitudinal axis of the bullet, in the present embodiment there being four grooves and each of the grooves having a substantially 90° included angle at its base. This leaves, therefore, four elongate flanges 5 in a cruciform shape as shown.
  • the grooves 4 extend to the nose 3 of the slug (see Figure 2b) and the slug thus presents a much smaller frontal area than a conventional slug with a corresponding increase in the ability of the slug to penetrate what it hits.
  • a sabot formed of a resilient plastics material such as nylon is mounted in use.
  • the sabot 6, as seen in Figures 2a, b, c, has a generally cylindrical body part 7. Extending from the body part 7 are a plurality, in the present embodiment four, fingers 9, each of which extend generally parallel to the central axis (7') of the cylindrical body part 7 and each of which, when viewed in cross section as in Figure 2a, comprises a substantially 90° segment which is a close fit within a respective groove 4 in the bullet.
  • the fingers of the sabot fill the grooves of the slug behind the crimp to prevent gas leakage through the grooves at ignition.
  • the slugs 1 have an ogival shape, the ratio of the length of the slug to its diameter approaching unit.
  • Each of the fingers 9 in the first slug has a hollow in its radially outer surface to lighten the sabot in order to reduce the weight of the cartridge to that of a conventional cartridge.
  • the metallic elements 14 shown in Figures 3a and 3b comprise steel elements of equilateral curved triangular shape fitting congruently within the grooves 4 in the second slug 1.
