Definitions

• the invention relates to a completely disassembling floor as a shell floor.
• the object of the invention is therefore to find a projectile which protects the bullet catches on shooting ranges at the same point of impact as the projectile ammunition and completely disassembles when it hits hard target structures, for example steel plates.
• a shell which can be a partial shell or full shell, the core of which consists of bullet-free pressed balls or granules made of a metallic material. All materials that can be pressed into a void-free core are suitable as the material for the balls or the granulate. Lead-free materials are preferably used for reasons of environmental protection, to avoid lead dust and contamination of the floor.
• the complete disassembly, the bursting, of the projectile reduces the energy area density in the target. This reduces the penetration performance compared to conventional jacket bullets with a core made of cast lead.
• the compressed bullet core made of spheres or granules held by the bullet shell disintegrates with the bullet shell on impact at the target.
• the grain size of the granules or the diameter of the balls determine both the energy output and the predetermined breaking points in the core of the projectile and thus the size of the individual parts that arise when it is disassembled.
• the size of the balls or granules is, depending on the caliber, between 1 mm and 12 mm, preferably between 3 mm and 6 mm.
• the balls with the largest diameter are used, for example, with .50 caliber.
• the projectile cores can also be composed of spheres or granulate particles of different sizes.
• the projectile core can also be composed in such a way that the front area, for example the ogival area, consists of spheres or granulate particles of smaller size than the cylindrical part.
• the core breaks down into many small fragments as soon as it hits it.
• the two areas cannot be pressed together. Each area must be pressed individually.
• the balls or granulate particles of different sizes can also consist of different materials, but the optimal center of gravity in relation to the ballistics must be guaranteed.
• the balls or granulate particles can be coated with a separating substance before pressing in order to ensure better disassembly in the target.
• Suitable release agents are, for example, graphite or polytetrafluoroethylene (Teflon).
• the projectile cores can also be prefabricated, i.e. pre-pressed into the bullet shape, into which the coats are inserted.
• predetermined breaking points in the jacket are advantageous.
• the predetermined breaking points run in the axial direction and lie on the inside of the manteis, preferably in the ogival area.
• the disassembly of the storey can be influenced by the number and location of the predetermined breaking points in the jacket. The closer the predetermined breaking points are to the top of the projectile, the sooner the coat mushrooms and breaks up into fragments. Further predetermined breaking points can be indentations running radially on the outer circumference, such as a coulter edge on hunting bullets.
• Copper, its alloys, plated steel, soft iron and zinc-tin alloys are particularly suitable as materials for the jacket.
• the invention is explained in more detail using exemplary embodiments.
• FIG. 1 shows a partial jacket bullet, shown in section on one side
• FIG. 2 shows a bullet jacket bullet, also shown in section on one side.
• a partial jacket floor 1 is shown.
• the core material was filled into the initially undeformed, open projectile shell 2 and then pressed into the core 3 without voids.
• the core material in the present exemplary embodiment consists of large balls 4 and small balls 5.
• the projectile jacket 1 was drawn into the projectile shape shown. In this way, a compact projectile core 3 with predetermined breaking points has been created between the pressed balls.
• the projectile jacket 2 is not closed in the projectile bow 6.
• the projectile core 3 emerges from the opening 7 of the casing 2 and forms the projectile tip 8.
• predetermined breaking points in the form of grooves 11 pressed into the casing 2 run on the inside of the casing 2 in the direction of the axis 10 of the projectile
• the rear 12 of the projectile 1 has a calotte 13 to stabilize the projectile movement and thus to increase the precision.
• coulter edge 14 In the cylindrical region of the projectile 1 there can also be a so-called coulter edge 14, a notch on the outer circumference of the casing 2 with a sharp edge , which forms a further predetermined breaking point when dismantling the jacket 2. It is particularly advantageous for hunting bullets, since it requires a clean bullet in the ceiling of the game.
• a solid jacket floor 15 is shown in FIG.
• the projectile jacket 16 is closed in the projectile tip 17.
• the core material consists of granules 18, which were first filled in through the open rear 19 and then pressed into a compact core 20 without voids. Subsequently, the rear area 19 of the floor 15 was provided with a cover 21 and jammed. Here too, a compact projectile core 20 with predetermined breaking points between the granulate particles has been created.
