Definitions

  • the present invention relates to ammunition and is particularly useful in ammunition for use in conventional small arms weapons having non- rifled barrels.
  • a novel ammunition round comprising 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.
  • DE-C-583098 discloses 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 in accordance with the preamble of claim 1 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 slug which has a plurality of grooves in its outer surface, each of the grooves being substantially "U” shaped in cross section and containing a plurality of spherical bodies arranged in rows in each of the grooves, characterized in that the slug is of ogival shape that the grooves extend helically around or substantially parallel to the longitudinal axis of the slug, and that the spherical bodies have a diameter substantially equal to that of the cross-section of the grooves to support and stabilize the slug in a barrel through which it is fired.
  • the ammunition of the invention is intended for use primarily as a shotgun slug and the bullet or slug may be made of steel or, as conventional, of lead.
  • the spherical bodies lying in the grooves may be formed of steel, plastics or any other suitable material.
  • the slug will preferably be formed of lead, for use e.g. when deer hunting, with a normal shotgun.
  • a military version would be formed of steel, with steel balls in the grooves, thus additionally providing a multiple projectile round.
  • the balls scatter like a shotgun for short range and the central streamlined projectile has long range energy and accuracy, so the round can be used as in applications normally requiring a rifle.
  • the flutes or grooves reduce frontal area and wind resistance to aid streamlining and form fins to help stabilize the slug in flight.
  • the balls in the grooves prevent the streamlined slug, with its ogival shape, from tilting in the barrel.
  • Normal shotgun slugs as for example, shown in the prior art referred to above, have a cylindrical shape which prevents tilting, but are not streamlined.
  • the balls stabilize the slug and separate from it equally well whether the grooves are helical or parallel to the axis of the slug, but if they are helical then windflow through the grooves after separation of the balls begins to spin the slug and stabilize its flight to improve accuracy.
  • a steel slug 1 of conventional ogival outline has four helical flutes 2 equiangularly positioned around its central axis 3.
  • four spherical bodies 4 are positioned, each of the spherical bodies 4 having a diameter substantially the same as although slightly less than the diameter of the cross-section of the flute 2.
  • the spherical bodies are also preferably made of steel and may be conventional ball bearings.
  • the circular sectioned wall of the flutes 2 supports the spherical bodies 4 which are retained within the flutes 2 in the radial direction, prior to firing by the wall of the casing, and after firing by the wall of the barrel.
  • the rear of the slug 1 may be abutted by a plug (not shown) in order to provide a satisfactory seal to the casing (not shown) to prevent the blast from the explosion of the charge passing around the sides of the slug.
