Definitions

  • the invention relates to a two-part or multi-part jacketless mostly lead-free partial decomposition projectile for hunting and a one-piece in material, outer shape and weight equal sister bullet for sports practice shooting.
  • a partial decomposition projectile includes a predetermined collapsible portion, a non-separable portion disposed behind in the direction of firing, namely, a tail or a residual pin, and a connecting portion connecting the bow and the stern.
  • the collapsible section disassembles after firing from a weapon only upon impact and during or after penetration into a target body.
  • the non-separable section then flows through the target body.
  • the bullet can be inserted into conventional sleeves to form a cartridge.

  • a simple and cheaper lead-free projectile is needed for practice shooting on the shooting range or in a shooting range, the same hunting style with the same sight setting and agreement in the target has no significant change in the hit result.
  • the hunter can use his weapon for hunting and sporting practice shooting alike, without having to adjust or adjust the sighting device.
  • Lead-free jacketed bullets which behave similarly as lead-containing jacketed bullets and bullets.
  • Lead-free sheaths usually have one or more cores made of soft material such.

  • Full projectiles mostly made of copper-zinc alloys, often have a blind hole drilled from the bullet nose point and an open or concealed hollow point.
  • external break points often as a groove or notch, attached.
  • the rest of the bolt is formed only when parts of the projectile bows with sufficient back pressure on or tear.
  • the mass and shape of the residual bolt are influenced by the nature of the projectile material, the shape of the projectile bow and the prevailing dynamic pressure when penetrating into the target body. The dynamic pressure in turn depends on the impact velocity of the projectile and the nature of the target medium.
  • Known bullets often require high impact speeds to achieve the desired effect, or act as desired only in a predetermined speed window.
  • weak game e.g., roe deer
  • strong game e.g red deer, wild boar and large antelopes
  • the consequences would be longer escape routes, a later death of the game and too few game marks for the search of the injured animal.
  • Extremely high impact velocities very often lead to the bursting of organs and to large bruises, which in turn can lead to a game devaluation (loss of meat).
  • the fragmentation quantity or the formation of a flag are also different in size and quantity. Sometimes a bullet can burst completely, tear off projectile flags or the remaining bolt or even the entire projectile can roll over in the target body.
  • the copper-zinc alloyed solid or multi-part projectiles in the transition cone of the gun barrel and to reduce the friction when penetrating the trains and fields of the run are small or soft contact surfaces of the basements state of the art.

  • the DE 102 57 590 A1 describes a rifle bullet for hunting purposes with a jacket made of a lead-free, soft-toughened material and a core connected to the shell of a material which is softer with respect to the jacket.
  • the task is to improve such a rifle bullet so that it provides a sustainable Thomashaar- and sweat formation at the bullet, fungus controlled fungus under significant cross-sectional enlargement, thereby only slightly disassembled and has a high residual weight (90% or more).
  • the rifle bullet has a Phynmanteligen bullet head and has at the transition point of the shell from the bullet head to a much thick-walled rear part on the outside a strong sharpening edge.

  • the object of the invention is to provide a Clzerlegungs-hunting projectile, which meets the requirements for cost-effective production and to a proper function.
  • a two-part or multi-part hunting projectile which is composed of a section which is front and forwards separable in the firing direction and / or a bow and a section or tail or residual bolt arranged in the firing direction behind it and not separable.
  • the bow and stern are directly coupled to each other, so without the interposition of other essential components. The coupling takes place via the compression cylinder, which extends either in the bow or in the rear or in both and in at least one of them can be inserted or pressed.
  • the invention therefore turns away from designing a projectile from a uniform or continuous jacket and a core enclosed by it. Rather, it pursues the principle of dividing the projectile transversely to its longitudinal direction and forming the two parts, namely the bow and the tail, coupled to each other. This makes it possible to adapt to all requirements, both the production and its use bullet, which can be produced both with largely conventional machines and shows in use the desired behavior of a partially disassembling and a residual bolt forming projectile.
  • the compression cylinder has essentially the task of connecting the bow and the tail with each other. For this he can be plugged into both the bow and in the rear. This results in a three-part hunting floor.
  • the compression cylinder is integrally formed on the bow and connected to the rear or integrally formed on the rear and connected to the bow. In the other part of the hunting projectile, with which he is not formed integrally, the compression cylinder can be inserted unchanged.
  • the compression cylinder may be a round or angular or at least partially conical cylindrical body, with a fit to the bow or the Rear, in or he can be plugged or pressed, is formed. He can thus connect the bow and the rear non-positively and / or positively.
  • the one-piece design with the bow or the tail results in a two-part projectile, the production cost is lower because one component has less to be mounted.
  • the compression cylinder may not adversely affect the subsequent disassembly of the bow and the shape of the tail as a residual bolt after the impact of the projectile on the carcass.
  • the compression cylinder may not adversely affect the subsequent disassembly of the bow and the shape of the tail as a residual bolt after the impact of the projectile on the carcass.
  • the compression cylinder can therefore be mounted between the compression cylinder and the bow or the rear of an annular circumferential groove which serves as a predetermined breaking point.
  • the annular circumferential groove is conveniently located at the point at which a diameter jump between the outer diameter of the bow or the tail on the one hand and the compression cylinder on the other.
  • the breaking point is thus so in that area in which the bow rests on the rear and thus in the plane of a separation or contact surface between the bow and the rear. If the compression cylinder breaks at the predetermined breaking point, the bow and the stern are separated from each other.
  • the annular groove is at the diameter jump between the bow and compression cylinder. Otherwise, serving as a predetermined breaking point annular groove between the compression cylinder and the rear.
  • the annular groove thus ensures a reliable separation between the bow and stern after the impact of the projectile on the carcass, so that in any case the tail can flow through the animal body undisturbed by the compression cylinder as largely dimensionally stable, cylindrical rest body.
  • the compression cylinder is hollow. He thus has a tubular shape, which is very stable in the radial and axial directions, but supports the effect of the annular groove as a predetermined breaking point.
  • the hollow or sleeve-shaped compression cylinder can thus be more easily separated from that projectile part, with which it is integrally formed.
  • the bow can have an open, partially concealed or completely concealed hollow point.
  • An open hollow point can be from a front or the tip of the bow or from a back, namely its separation or contact surface, with the bow at the rear is present, introduced.
  • a partially concealed or completely concealed hollow point can be introduced from a rear side into the bow, for example through a hole.
  • Their diameter may be based on weight criteria for the bow and / or desired fragment size and / or splitter size. In any case, he also determines the stability of the bug and thus his behavior in the collision of the partial decomposition projectile on the carcass. The larger the diameter of the hole in the hollow point, the sooner or easier or at lower speeds, the bug breaks down when hitting or after entering the carcass.
  • Another decisive advantage of this invention is in particular that the predetermined shape and mass of the tail or residual bolt at impact speeds between 600 to 1000 m / sec. As little or as little as the size of the carcass, bow formation and splintering influence it.
  • the bow has a rounded-conical, so-called ogive outer contour. It is common in long shots.
  • a through hole or blind hole for forming a hollow point regularly has a cylindrical inner contour.
  • the bow may have a wall thickness increasing towards the rear, which consequently represents an increasing resistance on impact. It can adversely affect the desired decomposition result.
  • According to a further advantageous embodiment of the invention can therefore be mounted in the bow concentric blind holes of different diameters for the formation of at least a partially concealed or fully concealed hollow point. Although this can not achieve a uniform and constant wall thickness in the bow. But by a clever gradation of the diameter of the blind hole wall thicknesses can be achieved from a defined minimum to a maximum thickness. This can be used to ensure a breakdown of the bug on impact into predefined chips in size and number.
  • the bow may have grooves as predetermined breaking points. They may, for example, be mounted annularly and in each case preferably at a diameter jump between the different diameters of the blind bores, either inside or on an outside of the bow. Thus, they enhance the effect of blind holes with different diameters and support the predetermined disassembly of the bug.
  • grooves may alternatively, additionally or exclusively extend in the axial or longitudinal direction of the bow. They too can be mounted on an outside of the bow and / or on an inside, namely in the hollow point.
  • At least one groove can be formed as a predetermined breaking point on the compression cylinder. Also, it can - as described above to the bow - run annular on an inner side of the hollow compression cylinder or on its outside. Alternatively and / or additionally, at least one axially extending groove can ensure reliable dismantling of the compression cylinder in the event of impact or intrusion.
  • the bow can be composed of several components, which consist of different materials.
  • the components are composed of concentric conical, disc or annular bodies so that together they form the bow.
  • the different materials are an additional or alternative way to break the bug into much the same or similar splinters. Interfaces between the different components and thus between the different materials can in turn serve as predetermined breaking points.
  • the compression cylinder can serve to hold together the different components of the bug also together and to connect them together with the rear.
  • the residual billet with its sharp-edged and shoulder-stable front surface, the former contact surface to the bow, should flow through the carcass largely directionally stable.
  • the front surface of the rest of the bolt should deform as little as possible, but retain a streamlined sharp-edged edge. It ensures the smoothest possible cutting edge when penetrating into the carcass in the fur and then for the directional stability of the residual bolt when flowing through the carcass.
  • the rear of the projectile is made of a softer material for manufacturing or weight reasons, it can be given a stable front by a cavitator disk made of a harder material.
  • a cavitator disk made of a harder material.
  • Guides can be mounted on the largest circumference or on the geometric jacket of the projectile. They define a small, but precisely dimensioned contact surface and ensure with low pressure increase good bullet guidance and sealing in the barrel, which is thereby spared and receives a longer service life.
  • the bullet can therefore have on the outside or on the geometric jacket of the stern between two guide belts an annular peripheral crimp.
  • the Crimprille ensures next to a predetermined Geunterposition in a cartridge case (setting depth) after the squeezing of the sleeve material in the Crimprille for a firm Geuntersitz.
  • the Crimprille can have a preferably inclined towards the bow groove bottom, which merges with a substantially rectangular step or a puncture by 90 ° in a subsequent guide belt.
  • the step or the puncture provides a sleeve mouth with the same sleeve length a defined contact edge and causes the sleeve mouth can not be moved towards the bow or the bullet during loading or unloading, especially in the shooting of the cartridges from self-loading weapons not in the Sleeve mouth is pressed, but the setting depth always remains the same. This promotes a uniform shot development with high precision.

  • the blind hole 51 has a conical widening 52.
  • a ring notch 53 is disposed in the contact surface 29, which is the lower annular groove 6 (see. FIGS. 9, 10 ) replaced as a predetermined breaking point between the compression cylinder 50 and the rear 3.
  • the inventive partial separation hunting bullet 1 in the carcass receives a larger cross section at the rear 3 and produces a larger rejection in the carcass.
  • a two- or multi-piece hunting bullet ( Fig. 1, 2 ) proposed, which is composed of a bow (2) and a tail (3), which are coupled directly to each other, ie without the interposition of other components.
  • a one-piece sports floor ( Fig. 26, 27 ), which is similar in shape and weight of the hunting ground and therefore can serve for training purposes.
  • the non-jacketed subdivision projectile for hunting exercise has a prefabricated as a residual bolt bullet tail (3), the invention has a round or square or at least partially conical hollow compression cylinder (4) with predetermined breaking points (5) as a solid base connecting element.
  • the projectile tail (3) and the one- or multi-part projectile (2) are non-positively and / or positively connected via the compression cylinder (4).
  • an aerodynamic projectile shape is fundamentally desired.
  • a shoulder-stable, sharp-edged bullet body (residual bolt) is required.
  • the aerodynamic shape is mainly used by the projectile bow (2). But it is only necessary until it hits the target body.
  • the tailstock serves as a residual bolt (3). It is preformed from the outset. It does not depend on the compression pressure as a function of speed.
  • FIGS. 1 and Fig. 2 show the projectile in a view and a partial sectional view.
  • Examples of a projectile bow (one or more parts) with different predetermined breaking points (7) and with concealed or open hollow point show the FIGS. 3 to 5 and FIGS. 6, 7, 8 .
