armor bullet

Background of the Invention

The invention relates to an armor-piercing bullet according to the preamble of claim 1, which is specifically intended for precision shooting with a handgun. Particularly well suited for use in long range rifles.

The present armor bullet comprises a so-called armor core surrounded by a sheath, made of a carbide known per se. The breaking properties of such a bullet only work when it hits a paint made of a hard material, such as metal. The bullet is therefore not a bullet bullet, but the bullet acts in the same way as a normal full-shell bullet when it strikes a soft material while remaining substantially intact in the paint.

It is known in the art to make such bullets with a particularly hard metal core, for example, by forming a sheath with a tip of copper alloy or copper-plated steel. The actual permeation core is placed inside this sheath. The bullet core is centered in the cavity formed by such a jacket such that the tip of the core is pressed against the tip portion of the diaper, after which the core is centered in the cavity of the diaper. One such bullet is disclosed, for example, in GB 2 316 471.

However, when firing such bullets, especially at longer distances ..i, it has become a problem to clearly detect the bullet's impact and thus i. ** to ascertain the function of the weapon and the accuracy of the shooter. This problem has traditionally been solved by the use of so-called light-barreled ammunition alternately in the weapon, whereby the ammunition left by these ammunition makes it easier to aim and indicates the bullet point of the bullet. the problem, however, is that they may differ slightly from the armor bullets that are otherwise used in flight characteristics, so the use of light projectiles may not give a sufficiently reliable picture of the firing result.

• ·· •. ·· ♦. 30 On the other hand, the impact of such a low caliber bullet on the finish is quite small, mainly limited to penetrating the paint or slightly breaking the structures. You can also try to increase the bullet's impact by using * * · bullet bullets in the weapon to light the target. Special ignition devices have also been made for this kind of ignition. 35 ammunition, often equipped with a phosphorus tip or a pyrotechnic • powder (magnesium, etc.). Apart from the fact that such firing ammunition is often intended to be used in serial firearms, it has a low accuracy in hit. In addition, the ignition media used are often highly flammable, requiring special care when handling projectiles.

BRIEF DESCRIPTION OF THE INVENTION It is an object of the present invention to overcome the drawbacks of the prior art by providing a novel solution to the construction and operation of the bullet.

This object is achieved by providing the armor bullet with the features defined in the claims according to the present invention. In particular, the present problems 10 can be solved by combining the characteristics of the bullet armor in a manner similar to that of claim 1.

Preferred embodiments of the invention are in the dependent claims.

In the context of the present invention, the term "handgun" means pistols, revolvers, rifles and similar hand-held firearms.

In turn, the term "bullet" in this application refers to a bullet which provides both a bullet firing effect during a bullet hit and an aid in detecting a hit due to the 20 flashes caused by the bullet hit.

The invention provides considerable advantages. Thus, the present solution provides a highly dimensionally accurate, stable, material-stable, bullet-balanced, flight-stable bullet with improved impact accuracy and a better spark * • * effect when striking the finish. 25 guarantees a great deal of targeting.

/ l · The bullet of the present solution is also easier to manufacture than previous light-barreled * * # and firing ammunition based on, for example, phosphorus or magnesium.

Because Titanium • ·· 30 or zirconium used in the armor bullet of the present invention are robust, stable materials, the bullet will withstand even heavy T treatment without damage or danger to the environment.

BRIEF DESCRIPTION OF THE DRAWINGS

In the following, some preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawing, in which: is adapted to extend beyond the sheath to form a bullet tip.

10 Detailed Description of Preferred Embodiments

Some preferred embodiments of the present armor bullet are described below with reference to the above figures. In this case, the armor bullet comprises reference numerals corresponding to those used in this specification.

Referring first to Figure 1 and the armor bullet 1 shown therein, as is known per se, the core 2 and the surrounding sheath 3. The sheath is conventionally made of copper-alloy or copper-plated steel and is surrounded by a core centered in a conventionally hard metal. The jacket then comprises a bullet 20 forming a bullet head 4 and a front 7 extending from the bullet tip 6 and a substantially cylindrical wall 8 extending between them which surrounds the receiving chamber 9 of the bullet.

/.*: The core 2, which is an elongated cylindrical or polygonal * * *. * / Shaped device, is disposed in the cavity 9 such that the first end 10 25 of the core is oriented to the bullet tip 6 and the second end 11 is • · * · "j arranged to orient toward the bullet base 4.

··. * 'At the first end 10 of the core 6 of the armor bullet 6 is provided with a shape-rigid sparking tip 12 fitted in the present armor 1, preferably made of titanium or zirconium. Such a sparking: ** [: 30 a tip comprising in the present embodiment a separate core in connection with. ·); insertable tool, can be made of titanium or zirconium preform by mechanical machining, for example turning. It is also conceivable that the sparking tip is made of titanium or zirconium powder in its respective form by extrusion in a manner known per se.

The sparking tip 12 according to the present solution has a recess 14 provided in the bottom 13 towards its core 2, which is in particular. ? for receiving the first end 10 of the bullet core. Thus, such a notch is shaped as closely as possible to the head of the 5 cores in order to ensure a uniform, balanced structure and thus the best flight characteristics of the bullet.

Conventionally, the tip portion 15 opposite the recess 14 in the sparking tip 12 is at least partially tapered.

The sparking tip 12 may be substantially substantially enclosed by the shell 3 extending to the bullet tip 6 as shown in Figure 1. As shown in the figure, the tip portion 15 of the sparking tip may be formed as a truncated cone, whereby the bullet tip may be made closed or at least partially open. However, there is nothing to prevent the projecting portion from always extending to the shell at the tip of the sealed bullet. "

Figure 2 illustrates another embodiment of the present armor bullet 1, wherein the armor bullet tip is formed of a tip portion 15 of a sparking tip 12 instead of a sheath 6, whereby the outer edge 16 in the wall 8 or front 7 of the sheath 3 is preferably associated with a sparking and to secure the tip. Such a groove is adapted to rotate a sparking tip: v. in a plane substantially perpendicular to the longitudinal axis of the bullet • · 18.

• a · • ♦ *. *. * 25 The present Armor Bullet 1 is safe to handle in normal storage, transport and shooting situations due to its 12 sparking hard and i * · · • **: chemically stable material. When the bullet hits • · t, the force exerted by the paint on the bullet bullet on the one hand and the force on the sparking tip 12 of the bullet core 2, on the other, causes a sudden increase in pressure on the sparking tip by: *] *. Sparkling. momentary flare of the tip will ignite volatile components such as fuel or gas at the point of impact. The flare also communicates clearly the location of the bullet to the • · **: ** shooter, thus facilitating a successful 35 shooting. i * * · • * • · • * · 4 117946 5

It will be obvious to a person skilled in the art that as technology advances, the basic concept of the present tank bullet can be implemented in many different ways.

Thus, the bullet bullet and its various embodiments are not limited to the examples described above, but may vary within the scope of the following claims.
