Abstract

The decomposition of a projectile in a target body, particularly a hunting projectile in wild animals after penetration therein, determines the energy output of the projectile and thereby the effect of the shot. For projectiles with double cores, the properties of the ingredients used in the cores decisively affect the decomposition and particularly the deformation behaviour of the cores. According to the invention, a partial decomposition projectile comprising two cores is provided with one solid core (3) made of a material suited to said projectile and the other core (4;22) is divided up into two areas (4a,4b;22a;22b), whereby one area (4a;22a) is made of ball-shaped elements made of a metal material granulate (5;23) and the second area (4b;22b) is made of a metal or ceramic powder and the ball-shaped elements or granulates (5;23) are pressed to become free of shrink holes, in order to improve decomposition behaviour control.

Description

Die Erfindung betrifft ein Teilzerlegungsgeschoss entsprechend dem Oberbegriff des ersten Anspruchs.The invention relates to a partial separation projectile according to the preamble of the first claim.

Die Zerlegung eines Geschosses im Zielkörper, insbesondere eines Jagdgeschosses im Wildkörper nach dem Eindringen in diesen, bestimmt die Energieabgabe des Geschosses und damit die Wirkung des Schusses. Bei schwachem Wild beispielsweise ist eine andere Zerlegung erforderlich als beim Hochwild. Aus der DE 102 39 910 A1 ist ein sich zerlegendes Jagdgeschoss als Mantelgeschoss bekannt. Es kann sowohl ein Teilmantel- als auch ein Vollmantelgeschoss sein, dessen Geschosskern aus Kugeln oder Granulat, lunkerfrei verpresst, aus einem metallischen Werkstoff besteht. Als Werkstoff für die Kugeln oder das Granulat eignen sich alle Werkstoffe, die sich zu einem lunkerfreien Kern verpressen lassen, unter anderem auch Blei oder bleihaltige Legierungen. Aus Gründen des Umweltschutzes, zur vorteilhaften Vermeidung einer Kontaminierung des Bodens und des Wildbrets, werden vorzugsweise bleifreie Werkstoffe verwendet.The dismantling of a bullet in the target body, especially a hunting bullet in the game after penetration into these, determines the energy output of the projectile and thus the effect of the shot. In weak game, for example, a different decomposition is required than in large game. From the DE 102 39 910 A1 is a decaying hunting ground known as a mantle projectile. It may be both a Teilmantel- 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.

Der vom Geschossmantel gehaltene verpresste Geschosskern aus Kugeln oder Granulat zerlegt sich mit dem Geschossmantel beim Aufprall im Zielkörper. Dabei bestimmen der Durchmesser der Kugeln oder die Korngröße des Granulats sowohl die Energieabgabe, als auch die Sollbruchstellen im Geschosskern und damit die Größe der bei seiner Zerlegung entstehenden Einzelteile. Größere Kugeln oder Granulatteilchen dringen tiefer in das Zielmedium ein und führen im Gewebe einen tiefer eindringenden Zerstörungskanal herbei als eine in der Masse vergleichbare Anzahl kleinerer Kugeln oder Granulatteilchen. Durch das Verpressen des Materials des Kerns entstehen scharfe Kanten an den verpressten Kugeln oder Granulatteilchen, die die Wirkungsweise der Splitter erhöhen.The compressed bullet core made of bullets or granules held by the bullet jacket breaks up with the bullet casing on impact in the target body. 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 during its 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. By pressing the material of the core, sharp edges are formed on the compressed balls or granule particles, which increase the effect of the splinters.

Aus der WO 01/20244 A1 und aus der WO 01/20245 A1 sind Deformationsgeschosse bekannt, die jeweils aus zwei massiven Kernen bestehen, wobei ein Kern der sogenannte Penetrator ist, der im Heck beziehungsweise im Geschossbug angeordnet ist und das Zerlegungs- und insbesondere das Verformungsverhalten des Geschosses maßgeblich beeinflusst. Bei diesen Geschossen erfolgt ein geringer Masseverlust der Kerne und ein Ausschuss mit definierter Restgröße des Geschosses.From the WO 01/20244 A1 and from the WO 01/20245 A1 Deformation projectiles are known, each consisting of two massive cores, with a core of the so-called penetrator, which is arranged in the rear or in the projectile bow and significantly affects the decomposition and in particular the deformation behavior of the projectile. In these projectiles there is a small mass loss of the cores and a reject with a defined residual size of the projectile.

Aus der Schrift WO 97/20185 ist ein Geschoss für kleine Kaliber mit zwei Kernen bekannt, wobei der Kern in der Geschossspitze aus einem harten Metall wie Eisen, Wolfram, Molybdän oder Legierungen davon besteht und der dahinter angeordnete Kern dagegen aus einem weichen Werkstoff. Der zweite Kern kann beispielsweise aus einem gepressten oder gesinterten metallischen oder nichtmetallischen Pulver bestehen.From the Scriptures WO 97/20185 For example, a bullet for small caliber with two cores is known, wherein the core in the bullet tip made of a hard metal such as iron, tungsten, molybdenum or alloys thereof and the core arranged behind it, however, made of a soft material. The second core may be made of, for example, a pressed or sintered metallic or non-metallic powder.

In dem US-Patent 4,939,996 wird ein mantelloses Geschoss aus gesinterter Keramik beschrieben, dessen Kern nicht unterteilt ist.By doing U.S. Patent 4,939,996 describes a shellless bullet made of sintered ceramic whose core is not subdivided.

In der deutschen Offenlegungsschrift DE 10239910 A1 wird ein sich zerlegendes Jagdgeschoss als Mantelgeschoss vorgestellt, dessen einteiliger Kern aus Kugeln oder aus Granulat aus einem metallischen Werkstoff besteht, wobei die Kugeln oder das Granulat lunkerfrei verpresst sind und dadurch Sollbruchstellen im Kern entstehen.In the German Offenlegungsschrift DE 10239910 A1 is presented a disassembled hunting projectile as a mantle projectile, whose one-piece core consists of balls or granules of a metallic material, the balls or granules are compressed voids free and thereby predetermined breaking points in the core arise.

In der PCT-Veröffentlichung WO 00/73728 A2 (Basis für Anspruch 1) wird ein Geschoss beschrieben, das in der Geschossspitze einen Hartmetallkern als Penetrator aufweist und bei dem der zweite Kern aus einer kaltgepressten Mischung von Hartmetallpulver, beispielsweise Wolfram, und Leichtmetallpulver, beispielsweise Zinn, besteht, wobei ein Binder der Mischung zugegeben wird.In the PCT publication WO 00/73728 A2 (Basis for claim 1) is described a projectile having a hard metal core as a penetrator in the projectile nose and wherein the second core of a cold-pressed mixture of hard metal powder, such as tungsten, and light metal powder, such as tin, with a binder added to the mixture becomes.

In der europäischen Patentanmeldung EP 0997700 A1 werden ein Verfahren zur Herstellung eines schadstoffarmen Mantelgeschosses und ein danach hergestelltes Geschoss beschrieben. Das Geschoss weist einen Kern aus einer Mischung von Wolframpulver und einem Schmier- und Gleitmittel auf, beispielsweise Calziumstearat. Der Kern wird am Ende des Geschosses durch eine Ausgfeichs- und Dichtmasse, beispielsweise Zinn, abgeschlossen, die aber nicht die Funktion eines Kerns hat.In the European patent application EP 0997700 A1 be a method for producing a low-emission coat floor and a subsequent produced projectile described. The projectile has a core of a mixture of tungsten powder and a lubricant and lubricant, for example calcium stearate. The core is completed at the end of the projectile by a Ausgfeichs- and sealing compound, such as tin, but does not have the function of a core.

Die Aufgabe der Erfindung ist es, das Zerlegungsverhalten solcherart aufgebauter Geschosse weiter zu verbessern.The object of the invention is to further improve the decomposition behavior of projectiles of this type.

Die Lösung der Aufgabe ist im kennzeichnenden Teil des Anspruchs 1 offenbart. Sie erfolgt dadurch, dass die erfindungsgemäßen Geschosse jeweils einen massiven Kern, d.h. einen Kern aus Vollmaterial, im Heck oder im Geschossbug aufweisen und einen zweiten Kern, der vor oder hinter dem massiven Kern liegt, der nicht massiv ist und nochmals in einen, zwei oder mehrere Bereiche unterteilt ist.The solution of the problem is disclosed in the characterizing part of claim 1. It takes place in that the projectiles according to the invention each have a solid core, i. a core made of solid material, in the rear or in the Geschoßbug and a second core, which lies in front of or behind the massive core, which is not solid and is again divided into one, two or more areas.

Besteht der erste Kern aus lunkerfrei verpressten Kugeln oder Granulat kann die Lage des zweiten Bereichs, des lunkerfrei verpressten Pulvers, in Schussrichtung gesehen, vor oder hinter dem Teil aus lunkerfrei verpressten Kugeln oder Granulat liegen. Ein Verpressen der beiden Bereiche kann gemeinsam oder einzeln erfolgen. Die Kugeln oder Granulatteilchen sowie das Pulver können auch aus unterschiedlichen Werkstoffen bestehen, die sich auch vom Werkstoff des massiven Kerns unterscheiden können, wobei aber bei der Gestaltung der Kerne die optimale Schwerpunktlage in Bezug auf die Ballistik gewährleistet sein muss.If the first core consists of spheres or granules pressed free from voids, the position of the second region, the void-free compressed powder, seen in the weft direction, can lie in front of or behind the part of void-free compressed spheres or granules. A pressing of the two areas can be done together or individually. The balls or granules particles as well as the powder may also consist of different materials, which may also differ from the material of the solid core, but in the design of the cores the optimum center of gravity with respect to the ballistics must be guaranteed.

Die Größe der Kugeln oder des Granulats liegt, je nach Kaliber, zwischen 1 mm und 12 mm, bevorzugt zwischen 3 mm und 6 mm. Die Kugeln mit dem größten Durchmesser werden beispielsweise bei Kaliber .50 eingesetzt. Als Werkstoffe für die Kugeln und das Granulat eignen sich alle metallischen Werkstoffe, die sich lunkerfrei verpressen lassen und als Geschosswerkstoffe geeignet sind. In dem Kern-Bereich aus Kugeln oder Granulat können auch Kugeln oder Granulatteilchen unterschiedlicher Größe gemeinsam verpresst werden. Die Größen können so aufeinander abgestimmt sein, dass die kleinen Kugeln oder Granulatteilchen die Lücken zwischen den großen Kugeln oder Teilchen ausfüllen.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, caliber .50. Suitable materials for the balls and the granules are all metallic materials that can be pressed free of voids and are suitable as bullet materials. In The core area of balls or granules and balls or granules of different sizes can be pressed together. The sizes can be coordinated so that the small balls or granules fill in the gaps between the large balls or particles.

Die Korngröße des Pulvers richtet sich nach der gewünschten Energieabgabe und Tiefenwirkung der einzelnen Pulverteilchen im Zielkörper. Große Pulverteilchen haben eine hohe Tiefenwirkung, kleine Pulverteilchen dagegen haben nur eine geringe Tiefenwirkung, insbesondere im Wildkörper. Die Korngröße des Pulvers liegt zwischen 50 µm und 1 mm. Der Pressdruck richtet sich nach der Korngröße und liegt bevorzugt zwischen 1,5 und 4 Tonnen. Sintermaterialien und Bindemittel sind ebenfalls von Vorteil, wobei Bindemittel bei schlechter verpressbaren Werkstoffen als Füllmaterial zwischen den verpressten Werkstoffen sitzen kann.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 between 50 microns and 1 mm. The pressing pressure depends on the grain size and is preferably between 1.5 and 4 tons. Sintering materials and binders are also advantageous, wherein binder can sit in poorly compressible materials as filler between the pressed materials.

Die Kugeln oder Granulatteilchen können vor dem Verpressen mit einer Trennsubstanz beschichtet werden, um ein besseres Zerlegen im Ziel zu gewährleisten. Als Trennmittel eignen sich beispielsweise Graphit oder Polytetrafluorethylen (Teflon).The spheres or granules may be coated with a release substance prior to compression to ensure better disassembly in the target. Suitable release agents are, for example, graphite or polytetrafluoroethylene (Teflon).

Die Geschosskerne aus Kugeln oder Granulat können im Geschossmantel verpresst werden oder vorgefertigt, d.h. in die Geschossform lunkerfrei vorgepresst, in den Geschossmantel eingebracht werden,The bullet cores of spheres or granules can be pressed or prefabricated in the projectile shell, i. pre-pressed into the projectile shape free of voids, introduced into the projectile shell,

Die Geschosskerne können in gewünschter Reihenfolge einzeln eingebracht und verpresst werden. Dadurch entsteht ein Aufbau des Kerns mit klarer Trennung zwischen den verschiedenen verpressten Kernbereichen.The projectile cores can be individually introduced and pressed in the desired order. This creates a structure of the core with a clear separation between the different compressed core areas.

Der massive Kern kann auch aus gepresstern Kugeln oder Granulat bestehen, wobei aber eine sehr hohe, lunkerfreie Verpressung erfolgen muss. Ein massiver Kern aus hoch verdichteten Sinterwerkstoffen ist ebenfalls möglich.The massive core can also consist of pressed balls or granules, but a very high, void-free compression must be carried out. A solid core of highly compacted sintered materials is also possible.

Das Geschoss mit einem kompakten Kern und einem verpressten Kern kann auch nur aus einem zerlegbaren Material wie Kugeln, Granulat oder Pulver bestehen.The bullet with a compact core and a compressed core can only consist of a decomposable material such as balls, granules or powder.

Ist eine Zerlegung des Geschosses bereits beim Auftreffen oder in geringer Eindringtiefe bzw. bei geringeren Projektilgeschwindigkeiten gewünscht, sind Sollbruchstellen im Mantel von Vorteil. Die Sollbruchstellen verlaufen in axialer Richtung und liegen auf der Innenseite des Mantels, bevorzugt im ogivalen Bereich. Die Zerlegung des Geschosses kann durch die Anzahl und die Lage der Sollbruchstellen im Mantel beeinflusst werden. Je näher die Sollbruchstellen zur Spitze des Geschosses hin liegen, desto eher pilzt der Mantel auf und zerlegt sich in Splitter. Weitere Sollbruchstellen können auf den Außenumfang radial verlaufende Einkerbungen sein wie beispielsweise ein Scharfrand bei Jagdgeschossen. Eine Abrisskante, beispielsweise ein Scharfrand, am Übergang zum massiven Kern bewirkt ein Abreißen des Mantels. Halterillen dagegen bewirken ein Festhalten des Geschossmantels am Geschosskern.If a decomposition of the projectile is already desired on impact or in low penetration depth or at lower projectile speeds, 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.

a partial jacket floor, core arrangement according to FIG. 5 , shown on one side in section, in which the coat also has a sharp edge and two holding grooves.

In Figur 1 ist ein Teilmantelgeschoss 1 dargestellt In den zunächst unverformten, offenen Geschossmantel 2 wurde ein massiver Kern 3 aus einem für einen Geschosskern geeigneten Werkstoff eingesetzt. Darauf wurde das Kernmaterial des zweiten, des Bugkems 4, eingefüllt, der zwei Bereiche 4a und 4b aufweist. Der zur Geschossspitze 8 hin liegende Bereich des Bugkerns 4, der Bereich 4a, besteht aus Kugeln oder Granulat, lunkerfrei verpresst. Der nachfolgende Bereich 4b besteht aus lunkerfrei verpresstem Pulver. Die beiden Bereiche 4a und 4b sind jeweils einzeln in ihre Form vorgepresst und dann in den Geschossmantel 2 eingesetzt worden. Sie können auch direkt im Mantel verpresst werden.In FIG. 1 a partial jacket floor 1 is shown in the initially undeformed, open shell jacket 2, a solid core 3 was used from a suitable material for a bullet core. Then, the core material of the second, the Bugkems 4 was filled, which has two areas 4a and 4b. The area of the nose cone 4 lying towards the projectile nose 8, the area 4a, consists of spheres or granules, compressed free of voids. The following Area 4b consists of void-free pressed powder. The two areas 4a and 4b are each individually pre-pressed into their shape and then inserted into the projectile casing 2. They can also be pressed directly in the mantle.

Anschließend wurde der Geschossmantel 2 auf die dargestellte Geschossform eingezogen. Der Geschossmantel 2 ist im Geschossbug 6 nicht geschlossen. Aus der Öffnung 7 des Mantels 2 tritt der Geschosskern 3 hervor und bildet die Geschossspitze 8. Im ogivalen Bereich 9 verlaufen auf der Innenseite des Mantels 2 in Richtung der Achse 10 des Geschosses 1 Sollbruchstellen in Form von in den Mantel 2 gepresste Rillen 11. Im Heck 12 des Geschosses 1 befindet sich zur Stabilisierung der Geschossbewegung und damit zur Steigerung der Präzision eine Kalotte 13.Subsequently, the projectile casing 2 was pulled onto the illustrated projectile shape. The projectile casing 2 is not closed in Geschossbug 6. From the opening 7 of the casing 2, the projectile core 3 protrudes and forms the projectile nose 8. In the ogival region 9, predetermined break points in the form of grooves pressed into the casing 2 run on the inside of the casing 2 in the direction of the axis 10 of the projectile 11 Rear 12 of the projectile 1 is to stabilize the projectile movement and thus to increase the precision of a cap 13.

Das Ausführungsbeispiel nach Figur 2 hat ebenfalls einen in zwei Bereiche aufgeteilten Bugkern 4. Der Unterschied zum vorhergehenden Ausführungsbeispiel besteht darin, dass hier die Anordnung des Bereichs 4a, aus lunkerfrei verpressten Kugeln oder Granulat, gegenüber 4b, aus lunkerfrei verpresstem Pulver, vertauscht ist. Der Bereich 4b bildet die Geschossspitze 8.The embodiment according to FIG. 2 also has a divided into two areas bow core 4. The difference from the previous embodiment is that here the arrangement of the area 4a, from void-free compressed balls or granules, compared to 4b, from void-free compressed powder, is reversed. The area 4b forms the projectile tip 8.

Die Wirkungsweise aller beschriebenen Geschosse besteht darin, dass der kompakte Kern den gewünschten Aussschuss ergibt, die Kugeln oder das Granulat ermöglichen eine große Tiefenwirkung im Wildkörper und das Pulver verursacht eine große Schockwirkung.The effect of all bullets described is that the compact core gives the desired shot, the balls or granules allow a large depth effect in the game body and the powder causes a great shock effect.

Die Größenverhältnisse der einzelnen verpressten Kernteile werden abgestimmt auf das Geschossgewicht, das Kaliber und die gewünschte Wirkung im Wildkörper.The size ratios of the individual pressed core parts are matched to the projectile weight, the caliber and the desired effect in the game.

Beispiele:Examples:

  1. a) Erwünscht ist eine große Tiefenwirkung. Vorteiihaft ist
    • kompakter Kern für den Aussschuss
    • großer Kugel- oder Granulatanteil
    • geringer Pulveranteil
    a) Desirable is a great depth effect. It is advantageous
    • compact core for the shot
    • large ball or granule content
    • low powder content
  2. b) Erwünscht ist eine Tiefenwirkung bei schwerem Wild. Vortelhaft ist:
    • großer kompakter Kern für den Aussschuss
    • großer Anteil an Kugeln oder Granulat
    • geringer Anteil an Pulver
    b) Desirable is a depth effect in heavy game. Preliminary is:
    • big compact core for the shot
    • large proportion of balls or granules
    • low proportion of powder
  3. c) Erwünscht ist eine hohe Schockwirkung. Vorteilhaft ist:
    • kompakter Kern für den Aussschuss
    • großer Anteil an Pulver
    • kleiner Anteil an Kugeln oder Granulat
    c) Desirable is a high shock effect. Advantageously:
    • compact core for the shot
    • large amount of powder
    • small amount of balls or granules

Nach dem Auftreffen im Zielkörper öffnet sich der Geschossmantel, der verpresste Kern zerlegt sich in seine Einzelteile und gibt dabei die gewünschte Energie an das Wildbret ab. Auf Grund des verpressten Kerns erfolgt bei jedem Geschoss die gleiche Energieabgabe im Wildbret. Die Zerlegung dieses Geschosstyps ist unabhängig von der Auftreffgeschwindigkeit, weil sich der verpresste Kern sowohl bei hoher als auch bei niedriger Auftreffgeschwindigkeit zerlegt. Bei Kernen aus Sinterwerkstoffen oder mit Bindmitteln im verpressten Kern kann die Zerlegung des Kerns durch die Sinterdichte bzw. den Bindemittelanteil gesteuert werden.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. For cores made of sintered materials or with binders in the pressed core, the decomposition of the core can be controlled by the sintering density or the binder fraction.

Die Größenverhältnisse der Kerne richtet sich nach der gewünschten Schockwirkung und Tiefenwirkung im Wildkörper. Bestehen 50 % des Kerns aus verpresstem Pulver, entsteht eine hohe Schockwirkung mit Tiefenwirkung, abhängig von der Pulverteilchengröße. Bei 20 % des Kerns aus verpresstem Pulver entsteht eine geringe Schockwirkung mit Tiefenwirkung. Die Zerstörung des Wildbrets erfolgt in Abhängigkeit von der Pulverteilchengröße.The size ratios of the cores depends 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.

Das Ausführungsbeispiel nach Figur 3 ist mit dem nach Figur 1 vergleichbar. Der Unterschied besteht darin, dass der Heckkern 14 und der Mantel 15 einstückig sind. Der Mantel 15 ist aus dem Werkstoff des Heckkerns 14 durch Tiefziehen geformt worden und umschließt den Bugkern 4 mit den beiden Bereichen 4a und 4b, wobei letztgenannter Bereich die Geschossspitze 8 bildet. Die Wirkungsweise ist wie bei den Ausführungsbeispielen nach Figur 1 und 2.The embodiment according to FIG. 3 is with the after FIG. 1 comparable. The difference is that the tail core 14 and the jacket 15 are integral. The jacket 15 has been formed from the material of the tail core 14 by deep drawing and surrounds the bow core 4 with the two areas 4a and 4b, the latter area forming the projectile nose 8. The mode of action is similar to the exemplary embodiments FIGS. 1 and 2 ,

Das Ausführungsbeispiel nach Figur 4 unterscheidet sich von den vorhergehenden Ausführungsbeispielen grundlegend dadurch, dass der Bugkern der massive Kern ist. Das Geschoss 20 ist ebenfalls ein Teilmantelgeschoss. In den zunächst unverformten, offenen Geschossmantel 21 wurde zunächst das Kernmaterial für den Heckkern 22 eingefüllt. Der Heckkern ist in zwei Bereiche aufgeteilt. Der zum Heck 30 hin liegende Bereich 22a besteht aus Kugeln oder Granulat, lunkerfrei verpresst. Der nachfolgende Bereich 22b besteht aus lunkerfrei verpresstem Pulver. Die beiden Bereiche 22a und 22b sind jeweils einzeln in ihre Form vorgepresst und dann in den Geschossmantel 21 eingesetzt worden. Anschließend wird der massive Kern 24 aus einem für einen Geschosskern geeigneten Werkstoff als Bugkern eingesetzt und der Geschossmantel 21 auf die dargestellte Geschossform eingezogen. Der Geschossmantel 21 ist im Geschossbug 25 nicht geschlossen. Aus der Öffnung 26 des Mantels 21 tritt der Geschosskern 24 hervor und bildet die Geschossspitze 27. Im ogivalen Bereich 28 verlaufen auf der Innenseite des Mantels 21 in Richtung der Achse 29 des Geschosses 20 Sollbruchstellen in Form von in den Mantel 21 gepresste Rillen 30. Im Heck 31 des Geschosses 20 befindet sich zur Stabilisierung der Geschossbewegung und damit zur Steigerung der Präzision eine Kalotte 32.The embodiment according to FIG. 4 differs fundamentally from the previous embodiments in that the bow core is the solid core. The projectile 20 is likewise a part-shell projectile. In the initially undeformed, open shell casing 21, the core material for the tail core 22 was first filled. The tail core is divided into two areas. The area lying towards the rear 30 22a consists of balls or granules, compressed free of voids. The following area 22b consists of void-free pressed powder. The two areas 22a and 22b are each individually pre-pressed into their shape and then inserted into the projectile casing 21. Subsequently, the solid core 24 is used from a suitable for a bullet core material as a bow core and the projectile casing 21 is retracted to the illustrated projectile shape. The projectile casing 21 is not closed in Geschossbug 25. From the opening 26 of the casing 21, the projectile core 24 protrudes and forms the projectile tip 27. In the ogival region 28 predetermined break points in the form of grooves pressed into the casing 21 extend on the inside of the casing 21 in the direction of the axis 29 of the projectile Rear 31 of the projectile 20 is to stabilize the projectile movement and thus to increase the precision of a dome 32nd

Dieser Geschosstyp ist vergleichbar mit einem "Penetrator". Die Wirkweise unterscheidet sich von Figur 1, 2 und 3 dadurch, dass der verpresste Kern mit Pulvers, Kugeln oder Granulat erst zur Wirkung kommt wenn sich der Geschossmantel gelöst hat und den verpressten Kern freigibt.This bullet type is similar to a "penetrator". The mode of action differs from FIGS. 1, 2 and 3 in that the compressed core with powder, balls or granules only comes into effect when the bullet jacket has dissolved and releases the compressed core.

Das Ausführungsbeispiel nach Figur 5 hat ebenfalls einen in zwei Bereiche aufgeteilten Heckkern 22. Der Unterschied zum vorhergehenden Ausführungsbeispiel besteht darin, dass hier die Anordnung des Bereichs 22a, aus lunkerfrei verpressten Kugeln oder Granulat, gegenüber 22b, aus lunkerfrei verpresstem Pulver, vertauscht ist.The embodiment according to FIG. 5 also has a divided into two areas tail core 22. The difference from the previous embodiment is that here the arrangement of the area 22a, from void-free compressed balls or granules, compared to 22b, from void-free pressed powder, is reversed.

Eine Abrisskante bewirkt ein Abreißen des Materials am Übergang des massiven Kerns. Halterillen bewirken ein Festhalten des Geschossmantels am Geschosskern.A tear-off edge causes a tearing of the material at the transition of the solid core. Holding grooves effect a retention of the projectile shell on the projectile core.

Das Ausführungsbeispiel nach Figur 6 ist mit dem nach Figur 4 vergleichbar. Der Unterschied besteht darin, dass der Geschossmantel 21 weitere Merkmale aufweist. Im zylindrischen Bereich des Geschosses 20 befindet sich ein sogenannter Scharfrand 33, eine sich auf dem äußeren Umfang des Mantels 21 befindliche Einkerbung mit scharfer Kante, die bei Jagdgeschossen einerseits einen sauberen Einschuss in die Decke des Wildes bedingt und andererseits eine weitere Sollbruchstelle bei der Zerlegung des Mantels 21 bildet. Weiterhin befinden sich noch zwei Halterillen 34 auf dem Umfang des Mantels 21. Durch Verformung des Mantels wird der Kern fixiert. Außerdem tragen diese Halterillen 34 zur Herabsetzung der Reibung im Waffenrohr bei. Die zusätzlichen Merkmale des Geschossmantels sind nicht auf das vorliegende Ausführungsbeispiel beschränkt. Auch die Ausführungsbeispiele der Figuren 1 bis 5 können mit einem Scharfrand und/oder mindestens einer Halterille ausgestattet sein.The embodiment according to FIG. 6 is with the after FIG. 4 comparable. The difference is that the projectile casing 21 has further features. In the cylindrical portion of the projectile 20 there is a so-called sharp edge 33, located on the outer circumference of the shell 21 notch with a sharp edge on the one hand, a clean shot in the ceiling of the game on hunting and on the other hand another breaking point in the decomposition of the game Mantels 21 forms. Furthermore, there are still two holding grooves 34 on the circumference of the shell 21. By deformation of the shell of the core is fixed. In addition, these holding grooves 34 contribute to the reduction of friction in the gun barrel. The additional features of the bullet jacket are not limited to the present embodiment. Also, the embodiments of the FIGS. 1 to 5 can be equipped with a sharp edge and / or at least one retaining groove.
