Description

Disintegrating hunting bullet
The invention relates to a disintegrating hunting bullet in the form of a jacketed bullet.
The disintegration of a bullet in the body of a game animal after penetration into said body determines the energy output of the bullet and hence the effect of the shot. 8
With small game a disintegration is required which differs from that in the case of big game.
The object of the invention is therefore to find a bullet that upon penetrating into the target medium disintegrates, in a manner matched to the game animal to be hunted, into a defined quantity of fragments having a defined size.
With a view to achieving this object, a jacketed bullet is presented which may be either a soft-nosed bullet or a full-jacketed bullet, the core of which consists of balls } or granules made of a metallic material which have been press—-moulded so as to be cavity-free. Suitable by way of material for the balls or the granules are all materials that can be press-moulded so as to form a cavity-free core, inter alia also lead or lead-containing alloys. For reasons of environmental protection, with a view to advantageously avoiding contamination of the ground and of the game, use is preferably made of lead-free materials.
The press-moulded bullet core which consists of balls or granules and which is held by the bullet jacket : disintegrates with the bullet jacket upon impact in the target. In this connection the diameter of the balls or the grain size of the granules determines both the energy output and the predetermined breaking-points in the bullet core and hence the size of the individual parts arising in the course of its disintegration. Relatively large balls or granule particles penetrate more deeply into the target medium and bring about a more deeply penetrating channel of + destruction in the tissue than a number of smaller balls or granule particles comparable in mass. . As a result of the press moulding of the material of the core, sharp edges arise on the press-moulded balls or granule particles, which promote the mode of action of the fragments.
The size of the balls or of the granules is, depending on calibre, between 1 mm and 12 mm, preferably between 3 mm and 6 mm. The balls with the largest diameter are employed in the case of calibre .50, for example.
The bullet core may also be composed in such a way that the front region, for example the ogival region, consists of balls or granule particles of smaller size than the cylindrical part. As a result, the core already : disintegrates into many small fragments upon impact. Press moulding of the two regions cannot be undertaken jointly.
Each region has to be press-moulded individually. The - balls or granule particles of varying size may also consist of varying materials, in which case, however, the optimal position of the centre of gravity with regard to the ballistics has to be guaranteed.
The balls or granule particles may be coated with a separating substance prior to press moulding, in order to guarantee a better disintegration in the target. Suitable by way of separating agent are, for example, graphite or : polytetrafluoroethylene (Teflon).
The bullet cores may also be introduced into the jackets in prefabricated form, i.e. precompacted into the bullet shape.
If a disintegration of the bullet is desired already upon impact or at a slight depth of penetration or at lower projectile speeds, predetermined breaking-points in the jacket are an advantage. The predetermined breaking-points extend in the axial direction and are situated on the inside of the jacket, preferably in the ogival region. The disintegration of the bullet can be influenced by the number and the position of the predetermined breaking- points in the jacket. The closer the predetermined breaking-points to the point of the bullet, the sooner the jacket mushrooms and disintegrates into fragments. Further predetermined breaking-points may be notches extending + radially on the outer periphery, such as, for example, a sharp edge in the case of hunting bullets.
Suitable by way of materials for the jacket are, in particular, copper, alloys thereof, clad steel, soft iron and zinc/tin alloys.
The structure of the bullet core that has been described is suitable for all types of bullet that are capable of disintegrating partially or completely. These also include bullets with a partially hard core, with a core made of varying materials, and bullets with an additional non- disintegrating penetrator in the nose of the bullet or in the tail of the bullet, such as are known from
WO 01/20244 Al or from WO 01/20245 Al, for example.
By virtue of the design possibilities of the core of a : bullet that have been pointed out, it is possible to produce bullets that are matched to the particular intended use and that achieve an optimal effect in each instance at any impact speed by reason of their disintegration behaviour which is matched to said speed.
The invention will be described in more detail on the basis of exemplary embodiments.
Shown in schematised representation are:
Figure 1: a soft-nosed bullet, represented in section on one side, and
Figure 2: a full-jacketed bullet, likewise represented in section on one side.
In Figure 1 a soft-nosed bullet 1 is represented. The core material was poured into the initially undeformed, open bullet jacket 2 and then press-moulded in cavity-free manner so as to form the core 3. In the present exemplary embodiment the core material consists of large balls 4 and small balls 5. Subsequently the bullet jacket 1 was drawn into the bullet shape that is represented. In the process, a compact bullet core 3 with predetermined breaking-points between the press—-moulded balls has been formed. The jacket 2 of the bullet is not closed in the nose 6 of the bullet. The bullet core 3 protrudes from the opening 7 in the jacket 2 and forms the point 8 of the bullet. In the ogival region 9 predetermined breaking-points in the form of grooves 11 pressed into the jacket 2 extend on the inside of the jacket 2 in the direction of the axis 10 of the bullet 1. Located in the tail 12 of the bullet 1 is a indentation 13 for stabilising the motion of the bullet and hence for increasing the precision. In the cylindrical region of the bullet 1 there is located a so-called sharp : edge 14, a notch with a sharp edge located on the outer periphery of the jacket 2, which, on the one hand, determines a clean point of entry into the skin of the game animal and, on the other hand, forms a further
Ce predetermined breaking-point in the course of disintegration of the jacket 2.
In Figure 2 a full-jacketed bullet 15 is represented. The bullet jacket 16 is closed at the point 17 of the bullet.
The core material consists of granules 18 which were firstly poured through the open tail 19 and then press- moulded in cavity-free manner so as to form a compact core 20. Subsequently the tail region 19 of the bullet 15 was provided with a cover 21, and the latter was clamped. Here too, a compact bullet core 20 with predetermined breaking- points between the granule particles has been formed. A notch in the cylindrical part of the bullet jacket 16, as described in the exemplary embodiment shown in Figure 1, is denoted by 14.
