Definitions

  • the invention relates to a projectile for a handgun cartridge, with a projectile core and a core casing, the core consisting of a specifically heavier material than the casing and the core and casing are positively connected.
  • the core and the sheath that completely surrounds it to the bottom are connected to one another only by a slight compression at the bottom end of the sheath, so that when the core hits, the thin layer of the sheath immediately pierces and is alone penetrates into the target, whereby the desired penetration, but only a weak shock and man-stopping effect is achieved.
  • the invention is therefore based on the object of providing a projectile of the type described at the outset which satisfies the opposing requirements with regard to a high penetration rate and a man-stopping effect as well as a relatively short trajectory if the target is missed.
  • the invention solves this problem in that the projectile core forms circumferential, at most up to a diameter range determined by the maximum core diameter radially outward formings for form-locking connection with the core jacket and the core jacket is open to the projectile tip in a known manner. Due to this special positive connection between core and jacket, the mutual cohesion of core and jacket is strong enough to avoid separation when striking soft or plastic target media and to ensure a common penetration, the jacket being expanded and rolled up within the target medium, what leads to the desired man-stopping effect. The However, the form-fitting connection is again not so strong that it can also withstand the impact on hard target media, so that only the heavy projectile core penetrates into hard target media and the desired penetration effect occurs. The opening of the core jacket on the front makes it easier to roll it up into soft target media or to strip it off when it hits hard target media.
  • An advantageous embodiment of the invention is that the projectile core protrudes from the core jacket on the tip side, the cylindrical core jacket towards the tip being pulled axially beyond the cylinder part of the projectile core which changes into a conical tip part, or the tip-side end face of the core jacket is aligned with the envelope surface of the core tip can.
  • This loads the projectile effect by more or less protruding from the core, by the size of a free space between the core and jacket, the formation of the projectile tip and the like. adapt to special circumstances and optimize for certain target media.
  • the core jacket has axially running predetermined breaking points, the roll-up process of the jacket in a soft target medium can be facilitated and the man-stopping effect can be increased.
  • a projectile 1 for a handgun cartridge has a projectile core 2 and a core jacket 3, the core 2 being made of a specifically heavier material than the jacket 3.
  • the core jacket 3 is on the outer circumference in the base area with deformation undercuts 4 for the tight fit in the gun barrel when firing provided, for which sealing rings or sealing caps, not shown, can be fitted onto the core jacket.
  • Projectile core 2 and core casing 3 are positively connected to one another and the circumferential shapes 6 of the projectile core 2 for this form-fit connection lie within a diameter range determined by the maximum core diameter.
  • These grooves 6 are formed by a plurality of grooves or threads that are evenly lined up and ensure the desired cohesion between the core and the jacket.
  • the projectile 1 is seated in a conventional cartridge case 12 which is equipped with a primer 13 and has a powder chamber 14 for receiving the propellant charge.
  • An ignition channel 15 between the primer 13 and the powder chamber 14 allows the propellant to be ignited.
  • the projectile core 2 protrudes on the tip side beyond the core jacket 3, whereby, as in the exemplary embodiment according to FIG. 1, the core jacket 3 can be pulled axially beyond the cylindrical part of the projectile core 2, so that between the conical tip part of the projectile 2 and the core jacket 3, an annular free space 5 remains.
  • the projectile core 2 can protrude not only with its tip, but also partially with its cylinder part over the core jacket 3 and according to FIG. 3 the core jacket 3 can align with its tip-side end face in alignment with the envelope surface of the core tip.
  • the core casing 3 can be closed on the bottom without impairing the projectile effect, and from the embodiment according to FIG. 4 it can be seen that the projectile core 2 can have an arbitrarily shaped core tip, for example a blunt tip .
  • axially extending grooves are provided in the core jacket 3 as predetermined breaking points 11, which are arranged symmetrically and extend from the tip-side jacket edge to the area of the positive connection 6.
  • a projectile according to the invention hits a hard target medium, for example a steel plate
  • the projectile core 2 penetrates into the steel plate because it displaces the material located directly in front of the core tip.
  • the core jacket 3 deforms on the surface of the steel plate and increases its diameter centrally around the point of impact of the projectile core 2, while the projectile core 2 continues into the Steel plate penetrates. From a defined penetration depth, the positive connection 6 between the projectile core 2 and core casing 3 is released and the projectile core 2 continues, detached from the core casing 3, to continue its way through the steel plate.
  • the same steel plate was bombarded with commercial ammunition of the same caliber, the bullet weighing about 8 grams.
  • the projectile according to the invention for this experiment had a weight of 2.3 grams.
  • the commercially available projectile had little or no effect when it hit the steel plate, but the full penetration with residual effect was achieved behind the plate in the case of the projectile according to the invention.
  • a projectile 1 according to the invention hits a plastic clay block or another soft target medium, the projectile penetrates into the plastic target medium.
  • the core jacket 3 deforms by first widening over the entire circumference and detaching from the upper part of the projectile core 2 in order to roll up with increasing depth of penetration in the direction of the rear of the projectile, with a tip-side clearance 5 preventing the projectile core jacket 3 from expanding and rolling up favored the direction of the shot.
  • the diameter of the projectile 1 is considerably increased, which entails an increased energy output from the projectile 1 in the plastic target medium.
  • the positive connection 6 between core shell 3 and projectile core 2 does not come loose as when hitting hard target media, the undeformed projectile core 2 and the strongly deformed core shell 3 form a unit, whereby the deformation of the core shell 3 means that the projectile 1 is faster than comparable projectiles releases to the plastic target medium and comes to a standstill after a relatively short penetration path.
  • the core jacket 3 will tear along the predetermined breaking points 11 and, with increasing penetration depth, roll up in segments like the opposite direction of the shot, thereby further increasing the diameter of the projectile 1.
  • the invention is of course not limited to the illustrated embodiments and it also includes a variety of materials for the projectile core, such as steel, hard metal, tungsten and the like. and for the core jacket, such as aluminum, aluminum alloys, plastics and the like.,
  • the core jacket also entirely or partially with a protective layer of copper, plastic or the like. can be provided to protect the gun barrel, etc.
