Description

Jacketed bullet for handguns with low projectile speed, z. B. Handguns The invention relates to a jacketed projectile for handguns with low projectile speed, especially self-loading handguns. It is known that smaller caliber bullets only have a good stopping force can be achieved if the design of the projectiles is designed so that the Impact or penetration into the target, compression or shattering of the projectiles and thus an enlargement of the effective zone arises.

Achieving this compression and increased effectiveness is not very special difficult with projectiles that are fired at high speeds, e.g. B. Rifle bullets. At high projectile speed, z. B. a hole in the Front part of the mantle, a slight protrusion of the lead core from the mantle or the like, in order to achieve compression or shattering and thus a sudden effect.

Much more difficult is the fulfillment of the requirements for the invention given task for projectiles with relatively low speed, such as B. for revolvers, self-loading pistols and the like. At the usual speeds here from about aoo to 500 m / s it happens that even unclad lead bullets are not or only insufficiently compressed when penetrating the target. Such Bullets can then penetrate deep into the hit body and with it over time, perhaps also by bleeding to death or being taken out of service Cause serious damage to organs or death. The momentary effect but is very often a pitifully small one. Also the life-threatening opponent or the z. B. game to be killed by a catch often remains for a long time able to act and possibly dangerous for the shooter. This evil will still be aggravated by the fact that the high bullet speed also with full jacketed bullets Hydraulic-dynamic explosive effect occurring in the target with such projectiles low speed completely or almost completely absent.

The above abuses, in particular with ammunition for self-loading pistols, became apparent very early and severely. Attempts have therefore been made on various occasions to increase the effect by using a special design of the projectiles. So one has z. B. Searched to use bullets with a very flat shape of the front part (mushroom bullets). Apart from extremely high air resistance, such projectiles do not work satisfactorily in self-loading weapons, since there are disruptions during the transfer from the magazine to the barrel. Attempts have been made to avoid this disruption by placing a thin metal cap with a slender tip shape on the flat front part of the projectile. This metal cap then again reduced the deformability of the bullet so much. that the desired effect did not materialize. Furthermore, the partial jacket designs that are customary for hunting bullets have also been used and supplied for pistol bullets and the like, and are still used today. A use in noteworthy 2 aß does not take place, however, since such bullets with a finite exposed lead tip result in disruptions in large numbers when the soft tip in the magazine or on the rear part of the barrel is hit during the self-loading process. If, however, the jacket is pulled forward so far that the exposed lead tip can no longer hit and restrain, there is again no more deformation in the target.

There is an older suggestion known to have projectiles that alter their structure could probably be used as pistol projectiles in such a way that that the front shell part has been slit so that a plurality of substantially pointed jacket flaps are formed, which by pressing together form a substantially closed shape Create lace. The purpose of this measure was obviously the destruction of the cloak when hitting the target. Meanwhile this proposal was in turn disadvantageous in this way than the core mass in a projectile designed in this way almost up to the very top, that leashes success has that of the individual Mantle flaps of the front projectile part from the inside through the core mass in this way were supported so that the intended projectile deformation was again obsolete, especially when the bullet hits soft targets, for example pieces of meat of the body of the game hit, especially in the areas of lower projectile velocity. Tests carried out with such projectiles have shown that in particular in the Areas of lower projectile velocity when hitting soft targets the projectile despite. the shape of the slits in the jacket was essentially retained, without even achieving the desired shock effect.

For this reason the suggestion mentioned remained, although it was already became known in the previous century without any practical use. Indeed it is for self-loading handguns the condition today is that almost exclusively Full jacketed bullets are used, but that on all sides has too little effect of these projectiles is sued.

According to the present invention, a new projectile is created which with the simplest structure completely smooth, ballistically favorable and externally solid Has texture to the tip. At the same time, however, it results in even the slightest Speeds such as B. from the known pocket pistols type Browning and the like. fired, with absolute certainty such a projectile deformation in the target that next a sufficient depth effect necessarily also a maximum of width and shock effect is achieved, as far as the energy in the cartridge allows this at all.

The invention achieves the desired success in that at a Jacketed bullet for handguns with low projectile speed, e.g. B. Handguns, in which the jacket is closed to the tip and before the final one is produced Form is provided with recesses on part of its length at the front, so that after Completion of the storey shape the connection of the jacket wall in front on one Part of the projectile length is interrupted, the slotted shell part of core material is kept free and the projectile core itself in front, that is on the tip of the projectile facing face, is limited by an approximately flat surface.

Embodiments of the projectile constructed according to this law are shown in the drawing.

Fig. I shows the bullet jacket a in the drawn state, which consists of the Usual materials such as brass, tombac, copper, steel o. The like. Can exist; Fig 2 illustrates the with cutouts in the sense of the design according to the invention of the new storey provided jacket a in section. In this example there are four Cutouts provided; Fig. 3 shows the plan of Fig. 2. Fig. 4 shows the same jacket a after pressing in the lead core b, which is expedient only is carried out after the production of the serrations on the front part of the jacket.

Fig.5 shows the usual way in which the Finished form of the projectile can be done, the projectile a and the press die c in section, the press-in ram d and ejector e, on the other hand, in the view are shown.

Figure 6 shows a projectile according to the invention in the view.

Figures 7 to 9 show some other embodiments of the design of the front part of the jacket. It goes without saying that other construction measures, such as B. Grooves f (Fig. 8), g (Fig. 9) and any special soil shapes According to (Fig. 9) and the like, also on the projectile according to the invention in the usual way and of any kind and combination can be used.

The shape of the recesses on the front part of the jacket is particularly useful chosen so that, such. B. Fig. 6 shows the remaining coat spikes the final pressing of the projectile an essentially seamless jacket design result. If you let the cloak prongs run out to a point, this also results in the bullet tip has a practically closed shape. Cut the prongs of the coat a little something flat, this creates a kind of hole on the front part of the coat. One lets this is relatively small, so it interferes with the work of the cartridge in the weapon in no way, is also ballistically harmless, but it can collapse of the front part of the coat.

But it is not absolutely necessary for the essence of the invention that the shell parts unite to form a completely closed shape. Such as B. Fig. 7 shows, open gaps can also remain; these just may not be so wide, that through the exposure of core material to a greater extent, disturbances of the automatic Working of the weapon.

The number of recesses and their length, based on the floor length, can be regulated as required. The condition is, of course, that the mantle flaps have a Have sufficient strength not to be subjected to centrifugal force due to rotation of the projectile to be bent outwards about its longitudinal axis during the flight path. If you can see only a few rags, e.g. B. two or three, before and makes this still proportionate in short, the flexural rigidity is particularly great. Such projectiles would then suitable for high speed and rapid rotation (rifle bullets). Turns if you attach a larger number of lobes and possibly even greater length, this is the Strength a low. Such projectiles are then only suitable for low speeds and less rapid rotation, but result in extremely easy deformability in the target. Also by choosing greater or lesser wall thickness and corresponding The deformation property can be determined in the course of the wall thickness from the base of the tabs to the front of the projectiles easily and at will, depending on the purpose and use.

The peculiarity of all built according to the inventive idea The projectile consists of the following: The cavity in the front that has remained free of core material Projectile part allows the jacket flaps forming the front projectile casing part when hitting the target, even with the slightest resistance and low projectile speed, to collapse unhindered on the end face of the projectile core. This creates in the struck body a projectile with a practically flat face and one for cutting of struck parts, favorably shaped edge. The peculiarity of the new bullet is that it has no more parts than the ordinary jacketed bullets, namely only coat and core, and that it is like one in the weapon and in flight Ballistically favorable full jacketed bullet behaves, but one in the hit body Has an effect like a ballistic and also in terms of occupational safety Self-loading weapons unusable cylinder bullet with a flat face.
