EP2226606A2 - Partially expanding bullet for hunting purposes - Google Patents

Abstract

The partial decomposition projectile (1) has a strut core (2) and rear core (3). The strut core forms a dissembled part of a projectile, and a rear core forms a drift punch body of the projectile. The strut core and rear core are made of rigid material, whose hardness lies in Brinell rigid area. The strut core and rear core are made of zinc.

Description

The present invention relates to a subdividing projectile for hunting purposes according to the preamble of claim 1.

Modern rifle bullets must meet various hunting requirements. The most important of these requirements is the accuracy of the target. h., the precision shot from various hunting weapons. Furthermore, the game is to be killed quickly and great agony. This requires a latitude and depth effect of the projectile in the game body. To meet this requirement, the projectile is to disassemble in the game and at the same time retain a defined residual mass. This is achieved by the separation into two cores. Another requirement for modern rifle bullets is a Schnitthaar- and welding on the Anschuss, in order to facilitate a possible Nachsuche without any waste. Since the bullet often closes very quickly due to the elasticity of the skin, the skin and the underlying fat layer, a scrap with sweat formation is desirable even at the most unfavorable shooting angle.

These requirements come very close to the gun bullets attributed to the assignee and known worldwide under the trade names TUG (Torpedo Universal Bullet) and TIG (Torpedo Ideal Bullet). These projectiles have their origin in a for the company founder Wilhelm Brenneke on December 11, 1920 under the number 370 908 patented by the Reich Patent Office hunting floor.

These projectiles are subdivision projectiles with a shell of nickel-plated mild steel, which receives form-fitting two lead cores, a softer nose cone and a harder tail core. These bullets got their name because of their torpedo tail shaped soil. This floor has interior ballistic benefits. The dual core construction of the above mentioned Brenneke rifle projectiles ensures optimal energy release in the target with safe width and depth effect. This is done by the rapid deformation and disassembly of the front, soft lead core, while the rear, hard lead core in most cases leads to the desired rejects.

Characteristic for the TIG and TUG projectiles is a trained in the area of the bullet head Scharfrand, which provides cut hair and sweat in most cases at the junction.

This development line of generic subdivision projectiles, ie, with a soft bow core and a hard tail core, has been maintained for almost a century. This is also evidenced by a partial decomposition project (patented in 2007) ( EP 1 214 560 B1 ). This is a lead-free bullet. As metallic materials for this projectile copper, tin, zinc, iron, tungsten, titanium, silver, aluminum, tantalum, vanadium and alloys of these metals are proposed.

Object of the present invention is to provide a further generic partial separation projectile with a dual core structure.

This object is achieved with a Teilzerlegungsgeschoss having the features of claim 1.

Advantageous embodiments of the invention will become apparent from the dependent claims.

According to the invention, it is provided that the bow core and tail core consist of materials of equal hardness whose hardness values are in the Brinell hardness range (HBW) lie. Thus, the present invention breaks down with a view taken and practiced over many decades, which states that the nose core of subdivision projectiles must be softer than the tail core. Surprisingly, it has been shown that even with bow and stern cores of the same hardness, the desired Innenbalistik the projectile, namely a mushrooming and disassembly of the bow core and in most cases a committee is achieved.

This solution makes it possible in an advantageous embodiment of the invention to use the same materials for the bow core and the tail core, which brings significant manufacturing advantages in the manufacture of the projectile with it.

In an advantageous embodiment of the present invention, the bow core and the tail core are made of tin.

When using materials for the tail core and the nose core with greater hardness values up to 200 HBW, it may be advantageous to provide mushroom support in the form of hollow tips, the bow core in the longitudinal direction passing through through holes or blind holes with spreaders used to support the mushrooming of the bow core.

This in FIG. 1 shown partial decomposition projectile 1 corresponds in principle to the known TIG projectile of the applicant, while the in FIG. 4 shown Teilzerlegungsgeschoss 1 corresponds to the basic structure of the known TUG projectile of the Applicant. Accordingly, the two partial separation projectiles 1 according to FIGS. 1 and 2 a two-core construction with a nose core 2 and a rear core 3. Furthermore, these two partial decomposition projectiles 1 have a shell shell 4 (partial jacket shell) which is open at the nose of the nose and whose strength increases from the projectile nose to the stern. Characteristic of both Teilzerlegungsgeschosse 1 is still a sharp edge 5, which punctures a circular hole at the bullet and thus provides cut hair and sweat on the Anschuss, and a torpedo tail 6, which gives Innenbalistische advantages due to its bottom shape. Further, common features of the subdivision projectiles according to the FIG. 1 and 4 are circumferential holding grooves 7 and Crimprillen 8, although they are formed differently in two partial separation projectiles 1, but have the same functions. The holding grooves 7 serve, as the name implies, the hold of the tail core 3 on the projectile casing 4, while the crimping dies 8 produce a crimp connection between a cartridge case, not shown, and the partial decomposition projectile 1 serve.

In the partial decomposition projectile 1 according to FIG. 1 the tail core 3 at its bow-side end a funnel-shaped recess 9, in which a correspondingly shaped pin 10 of the bow core 2 engages positively. Both the bow core 2 and the rear core 3 are made of tin.

When hitting the partial separation projectile 1 according to FIG. 1 on a in game body of the bow core 2 mushrooms strongly, at the same time penetrates the pin 10 of the bow core 2 in the tail core 3, so that it is also aufgekelcht, ie its cross-section enlarged. The projectile casing 4 remains connected to the rear core 3. Due to the strong cross-sectional widening of the subdivision projectile 1 it causes a strong shock effect in the game body, so that the animal dies quickly. At the same time, the non-decaying tail core 3 in light and medium game in most cases ensures a committee.

The target balance of subdivision projectile 1 according to FIG. 4 differs from that of the subdivision projectile 1 according to FIG. 1 , This is mainly due to the fact that in the partial decomposition projectile 1 according to FIG. 4 the bow portion of the tail core 3 protrudes with a conical tip 11 in the bow core 2. This lies with a corresponding conical recess 12 form-fit to the tail core 3.

When hitting the partial sheath projectile 1 according to FIG. 4 on a game body, the bow core 2 mushrooms before it breaks down, so that by the cross-sectional widening also a shock effect is achieved in the game body. As a result of this mushrooming, the projectile jacket 4 breaks off at the crimping groove 8. The tail core 3 undergoes substantially no cross-sectional enlargement due to its conical tip 11, so that the partial decomposition projectile 1 according to FIG. 4 even in heavy game usually provides for a committee.

The partial separation projectiles 1 according to FIGS. 2, 3 and the FIGS. 5, 6 differ from the subdivision bullet according to FIG. 1 or according to FIG. 4 in that they are equipped with Aufpilzhilfen. Such Aufpilzhilfilfen are particularly required when using metallic materials with higher hardness values.

In the case of the subdivision projectiles 1 according to the Figures 2 and 5 the mushroom aid is designed as a thin through hole 13, which passes through the bow core 2 centrally from the bow to the rear.

In the embodiments according to the Figures 3 and 6 For example, the nose cone 2 has a blind hole 14 that opens into the tip and widens conically at the exit. In this blind hole 14 a the top of the decomposition projectile 1 forming spreader 15 is used made of a harder material. A shaft 15.1 of the expansion body 15 projects into the blind hole 14. The shank 15.1 is adjoined at the transition to the projectile nose by a conical enlargement which corresponds to the widening of the blind hole 14. The connection between the spreader 15 and the bow core 2 is made by material connection.
