Definitions

  • the invention relates to a partial separation projectile according to the preamble of the first claim.
  • a decaying hunting ground is known as a mantle projectile. It may be both a Generalmantel- and a solid shell projectile, the bullet core of balls or granules, pressed voids free, consists of a metallic material. Suitable materials for the balls or granules are all materials that can be pressed into a void-free core, including lead or lead-containing alloys. For reasons of environmental protection, to advantageously avoid contamination of the soil and venison, lead-free materials are preferably used.
  • the compressed bullet core made of bullets or granules held by the bullet jacket breaks apart with the bullet jacket on impact in the target body differently than a solid core.
  • the diameter of the balls or the grain size of the granules determine both the energy output, as well as the predetermined breaking points in the bullet core and thus the size of the resulting parts of his decomposition. Larger balls or granules penetrate deeper into the target medium and cause a deeper penetrating destruction channel in the tissue than a comparable number of smaller balls or granules particles.
  • sharp edges are formed on the compressed balls or granule particles, which increase the effect of the splinters.
  • BESTATIGUNGSKOPIE Deformation projectiles are known from WO 01/20244 A1 and WO 01/20245 A1, each of which consists of two solid cores, one core being the so-called penetrator, which is arranged in the rear or in the projectile bow and the disassembly and in particular the Deformation behavior of the projectile significantly influenced. In these projectiles there is a small mass loss of the cores and a reject with a defined residual size of the projectile.
  • the object of the invention is to further improve the decomposition behavior of a bullet with two cores.
  • the projectiles according to the invention each have a solid core, i. a core made of solid material, in the rear or in the projectile bow and a second core, which is not solid, but consists of void-free pressed powder and which lies in front of or behind the massive core.
  • the solid core and powder core can be made of different, bullet-proof materials, but in the design of the cores, the optimum center of gravity in terms of ballistics must be ensured.
  • the grain size of the powder depends on the desired energy release and depth effect of the individual powder particles in the target body. Large powder particles have a high depth effect, small powder particles, however, have only a low depth effect, especially in the game.
  • the grain size of the powder is therefore, depending on the desired effect, between 50 microns and 1 mm.
  • Sintering materials and binders are likewise advantageous, it being possible for binders to sit between the pressed powder particles as filler material in the case of poorly compressible materials.
  • the bullet core of powder can be pressed in the mantle or prefabricated, ie pre-pressed into the bullet shape void-free, be introduced into the mantle.
  • the pressing pressure depends on the grain size and is preferably between 1, 5 and 4 tons.
  • predetermined breaking points in the jacket are advantageous.
  • the predetermined breaking points extend in the axial direction and lie on the inside of the jacket, preferably in the ogival region.
  • the dismantling of the projectile can be influenced by the number and position of the predetermined breaking points in the mantle. The closer the predetermined breaking points are to the top of the projectile, the sooner the mantle mushrooms and breaks up into splinters.
  • Other predetermined breaking points may be on the outer circumference radially extending notches such as a sharp edge in hunting bullets.
  • a tear-off edge, for example a sharp edge, at the transition to the solid core causes the jacket to tear off. Holding grooves, on the other hand, cause the projectile shell to be retained on the projectile core.
  • the massive core can also consist of pressed balls or granules, with a high, void-free compression is beneficial.
  • a solid core of sintered materials is also possible.
  • the core of a solid shell or a partial shell projectile can also consist entirely of pressed powder. Such a projectile would be usable as a training projectile.
  • the described structure of the bullet core is suitable for all types of bullets that are teilzerlegbar. Due to the shown design possibilities of the core of a projectile it is possible to produce projectiles which are adapted to the respective intended use and which at each impact speed due to their coordinated

  • the bullet jacket After striking the target body, the bullet jacket opens, the compressed core disassembles into its individual parts and gives off the desired energy to the venison. Due to the compressed core, the same energy release occurs in game on each storey.
  • the decomposition of this type of bullet is independent of the impact velocity, because the compressed core decomposes at both high and low impact velocity.
  • the decomposition of the core can be controlled by the sintering density or the binder fraction.
  • the size ratios of the two cores depend on the desired shock effect and depth effect in the game. If 50% of the core of compressed powder is present, the result is a high shock effect with depth effect, depending on the powder particle size. At 20% of the core of compressed powder produces a low shock effect with depth effect. The destruction of venison takes place depending on the powder particle size.

Abstract

La désagrégation d'un projectile à l'intérieur du corps cible, notamment d'un projectile de chasse dans le corps du gibier après pénétration dans ce corps, détermine la production d'énergie du projectile et donc l'effet du coup de feu. Dans les projectiles à double noyau, le comportement de désagrégation et notamment le comportement de déformation des noyaux sont influencés de manière décisive par les propriétés des matériaux utilisés dans les noyaux. L'invention vise à améliorer la commande du comportement de désagrégation. A cet effet, dans un projectile à désagrégation partielle présentant deux noyaux, l'un (3) des noyaux est massif et est constitué d'un matériau apte à être un projectile et le deuxième noyau (4) est constitué de poudre (5) composée de matériaux métalliques ou céramiques, la poudre étant comprimée sans retassures.
