Abstract

The invention is intended to provide patent protection for a lead-free projectile for hunting purposes, in the case of which projectile a different effect in the target can be achieved, for the same hit point position, within one calibre by dividing the projectile tip into different numbers of sectors and cuts of different depth and/or different drilled hole depths. The pressing and friction resistance in the barrel is also reduced by means of relief grooves underneath a casing, and copper-coating of the barrel wall is prevented.

Description

This invention is intended to be a further lead-free multiple storey, or Protect the projectile and its manufacturing process which is provided with a coat and by number and or depth the sector cuts or through different depths and out again filled holes different effects in the target, also in conn dung with uncut bullets, bring in and at glide Chem weight, material, bullet shape and powder load same meeting achieve point position. A copper layer is formed by an outer jacket excluded the inner wall of the barrel.

There are solid shell bullets with lead core and lead shot bullets inside half a caliber, with the same weight, etc., known the same Have meeting point. However, a full coat bullet is for hunting Purposes hardly applicable. Solid jacket bullets are also allowed on some Shooting ranges, because of the great depth of penetration into the cover, not to be used.

Solid bullets are also known, which be made of relatively hard tombac stand and therefore a high injection and friction resistance in the barrel to have. This is also associated with a strong deposition of the floor materials in the run.

Eliminate the previously identified shortcomings and the number of uses bullets for hunting purposes, within one caliber To increase the same meeting point is the object of this invention. The Invention sees a floor with a core made of tombac, copper or The like. Which is enclosed on the outside by a coat. The Ge lap core can be cut in two or with different depths be divided into several sectors, or from a core without cuts consist. The bullet tip is kept relatively long to keep the spread if possible not to let the zone come into the jacket area. By doing A bore is provided in the front part of the projectile core different effects in the target, different from floor to floor Lich must be executed deep. If you want to achieve a weak effect,  so the hole only needs z. B. 3 mm deep, should stronger effect can be achieved, the hole can be 12 mm deep be brought. In this case, however, the cleared space must be moved around 9 mm again with a pencil, if possible, of the same specific heavy weight Material must be filled in to get the same meeting point like the 3 mm bored bullet.

The bullet core is covered with a coat, preferably made of tombac surround the other part. The jacket made of sudden steel (river iron) or another alloy. The coat can closed at the back or pushed as a pipe socket over the floor core be. To be absolutely solid when using a pipe socket as a jacket To achieve connection to the core, the two parts can be glued, Plastic, solder, beads or the like. To be connected together. The bead can be introduced into the floor at the point where the sleeve neck ends so that the sleeve neck end into the bead groove, because of the firm hold in the sleeve, can be pressed.

The projectile core needs because of the use of the jacket with regard to the Alloy and hardness can only be matched to the reaction in the target. There soft material (tombac) slightly mushrooms in the target and soft material also does not break so easily and the press-in and friction resistance diminished in the run is for targets where there is no breakthrough Power arrives, soft material, tombac, copper, an advantage. The Ge lap coat should be made of harder material, preferably tombac be and can fully relate to the internal ballistic stress Lich alloy and coating are aligned and no longer on the necessary target ballistic properties, so that copper plating the run can be excluded. The material shift at Entry of the projectile into the trains of the barrel takes place practically in the same way as in the case of a jacket storey with lead core.

Relief grooves of fine or coarse design can be made on the cylindrical part of the projectile core or in the casing. The depth of this relief grooves need not be greater than the field strength of the barrel, thus be about 10 to _^20/100. By means of these relief grooves, the press-in and frictional resistance, particularly in the case of medium-hard and hard cores, can be reduced further without a grooving occurring on the outer wall of the casing, which would result in a drop in speed in free flight. The creasing on the floor or in the jacket can be circumferential, or can also run parallel to the floor axis. In the latter case, the scoring is easy to bring in by pressing a corresponding nozzle. Scoring would also be advantageous for the introduction of the binder (glue), since the binder is easier to bring between the jacket and the projectile core. The coat can be formed on the front edge as a haircut edge. The relief grooves between the projectile core and the casing are particularly advantageous for Ge shots with a hard core because there is no copper plating of the barrel wall and an increased drop in speed of the projectile and thus a higher target energy is achieved.

The projectile can be opened at its front with a plastic cover to be finished. If the sector is divided over 2 sectors however the cap is made of hard steel and is made as a cone be educated. The tip of the cone supports when it hits a target spreading the floor in the center.

Two methods can be used to manufacture the projectile. The preferred method is the inner soft and exactly kali burnished and possibly provided with relief grooves rod material, e.g. B. of 3 mtr. Length, in a tube made of harder material made of tombac, with or without binders. Between the diameter of the core materials and the inner diameter of the casing tube should not there is greater tolerance. After inserting the core rod into the The superfluous binder can be pulled through a tube Pressed nozzle out and pressed the two parts together and kali be burned. After the glue has set, the turning process on the Automatic lathes start and bullet tips attached with the hole and be reached. Should the bullet be broken down into individual pieces Sectors to be desired when hitting a target must be the essence material previously divided into sectors and pressed again. The The method described above is particularly simple and inexpensive.

The second method to be used is that the core with the Tip, front opening and possibly with longitudinal Relief grooves, pressed and then annealed and descaled. The coat, preferably with bottom, is also known to be in the Pressing process made. After putting the two parts together a bead can be introduced, the two parts firmly together connects.  

If the bullet is disassembled after hitting it, too if a target is desired, the projectile core must be pressed before pressing speaking sector cuts can be provided by pressing or Saws can be introduced. In this case, the would not open cut core diameter in the tip according to the Taper the outer shape of the tip towards the front.

Bullets can be produced using the two methods described above that are two or more different within a caliber Have effects in the target, e.g. B. it is possible to manufacture a projectile, with deeply cut sectors and an approximately 3 mm deep front Opening. This projectile would hit the outside when hitting a target tear open coat and separate into pieces, according to the number of Sectors, disassemble.

Another floor could consist of a non-sectored one Core with jacket exist, but with a front drilling depth of z. B. 12 mm. However, the hole would be made with a 9mm long pin in the back Area closed again. The projectile would open at the top mushrooms and achieve a medium effect in the target.

Another bullet could turn at the top only with a 3 mm be deep hole that only a small mushrooming in front leads to the first tip area and because of the low expansion only for weak game.

Of course, it is also possible to have a storey divided into sectors only let the core mushroom in the tip area. In this case the depth of cut for the sector breakdown should only be small.

The coat needs, as is necessary for bullets with lead core, to have no reinforced zones, e.g. B. the expansion of the lead stop core. Since the floors described above predominantly in Mushrooming the tip area, however, would be a floor which further on mushrooms, from the outer coat made of harder material when mushrooming be braked.

It is also possible to do without the bullet jacket and the bullet to be made from one piece. In this case, the surface of the floor in the cylindrical guide area by rolling or pressing harder be made. It is also possible to galvanically coat a nickel layer to wear, but in this case a Ver copper cannot be completely excluded from the inside of the barrel.  

In the drawing are four embodiments of the invention Projectile shown on a greatly enlarged scale and shows

Fig. 1 is a multi-storey high potency in longitudinal section;

Fig. 2 shows a multi-storey high potency in cross-section,

Fig. 3 shows a projectile with Moderate effect in longitudinal section;

Fig. 4 shows a projectile with Moderate effect in cross-section,

Fig. 5 shows a projectile with a weak effect in longitudinal section;

Fig. 6 shows a projectile with a weak effect in cross-section,

Fig. 7 shows a multi-storey with Moderate effect in longitudinal section;

Fig. 8 is a multi-storey with a medium-strong effect in cross section.

The multiple storey shown in FIGS. 1 and 2 consists of a soft storey core 1 , a hard jacket 2 and a closure hood 3 . The projectile core 1 consists of soft annealed tombac and is divided into two sectors 4 by incisions 5 . In the casing 2 , a bead 6 is introduced, which continues into the core 1 of the floor. In the front part of the projectile core 1 , an opening 7 is seen before, which is filled with a closure 3 , preferably made of plastic. The protruding from the jacket 2 tip 8 of the projectile core 1 is kept as long as possible. The projectile core 1 is fastened with a binding agent in the casing 2 and the bead 6 . The front Kan te 9 of the jacket can be formed with sharp edges as a cutting edge.

When hitting a target, this projectile would be divided into two halves (sectors), the connection point 10 of the two sectors 4 and the jacket 2 tearing over the incisions 5 . The connection point 10 must not be kept too strong to allow a complete tear on. The floor described above has a strong effect on the target and it is created by dividing two committees.

The projectile shown in FIGS. 3 and 4 has the same structure, shape, weight and material hardness, but does not have any incisions 5 or 4 gates. The opening 13 in the projectile core 11 is continued as a blind hole 15 and filled with a pin 16 , the same material as the projectile core 11 . The front opening 13 is again provided with a closure hood 14 as in FIG. 1. The jacket 12 again serves as a cutting edge on the front edge 19 and is provided with a bead 17 which also continues into the core 11 of the projectile. The tip 18 has the same length and shape as the tip 8 in FIG. 1.

When this bullet strikes a target, the shell tip 18 spreads (mushrooms) up to approximately the beginning of the cut edge 19 of the casing 12 . The degree of mushrooming can be determined by the depth and diameter of the blind hole 15 . By filling the blind hole 15 with a pin 16 , the same projectile weight as in the projectile of FIG. 1 is produced. The projectile has a medium impact when hitting a target, as required for European game, and only one committee.

FIGS. 5 and 6 illustrates a projectile of the same weight, shape, structure and material are as bullets in Fig. 1-4. The projectile core 20 is again surrounded by a material 21 . In the front part, an opening 23 is again provided, which is closed with a closure hood 22 . The jacket 21 is again provided with a bead 24 and a cutting edge 25 .

Upon impact on a target, this projectile only about _^1/4 pilzt on the top 26th The diameter of this mushrooming corresponds approximately to the diameter of the projectile caliber. So only a weak effect is achieved in the target, which is quite desirable for smaller game species.

The projectiles as shown in Fig. 1-6 are the same in shape, weight and material, so that all three projectile types have the same meeting point with the same powder load. The hunter now has the option, depending on the game, to choose the appropriate projectile without having to re-shoot his weapon.

The above-described bullets of Figs. 1-6 have been manufactured according to the Merge of the core and cladding material ge on a lathe and then introduced the bead. With these projectiles, it must be ensured that the jacket and the core of the projectile are firmly connected to each other when fired. For this reason, a reliable glue connection between the jacket and the floor is appropriate. By means of fine relief grooves on the projectile core, the support of the jacket on the core is increased.

The projectile shown in Fig. 7 and 8 shown again comprises a Ge shot core 27 and a shell 28. The projectile core 27 is divided into four sectors 38 by cuts 37 . The projectile core 27 has obtained its shape by pressing, so that the cutting depth 37 adapts to the shape of the tip 35 , so that the cuts 36 are curved in the tip area. This facilitates the start of tearing when touching down on a target. In this case, the opening 30 is filled with a steel cone as the closure hood 29 . The projectile core 27 is provided on the outside in the region of the casing 28 with fine relief grooves 31 . The front edge of the jacket 28 is again designed as a cut edge 34 . In this case, the bead 32 in the jacket 28 is rolled in only weakly and only in the depth of the relief grooves 31 . At the rear, the floor is equipped with a conical rear part 33 .

When this projectile is fired from a weapon, the projectile first releases from the sleeve and enters the trains in the transition cone of the barrel. The fields press the jacket 28 inwards, so that the finest stress grooves 31 , or the remaining webs are compressed in the place without the projectile core 27 being deformed. This significantly reduces the press-in and frictional resistance and thus the risk of linking during the run.

When the projectile hits a target, the hood 29 is pressed into the projectile, so that the connection point 39 of the four sectors 38 in the tip region 35 tears apart. The conical, pointed shape of the steel closure hood 29 promotes the tearing open of the four sectors 38 in the center of the projectile. A jacket 28 with a base is not suitable for this floor. It must be ensured that the shell 28 and the core 27 do not separate when shooting from the projectile.

Of course it is also possible to make the shell of the projectile from one to manufacture other material, e.g. B. made of steel. It is also possible ver to the cut edge formed by the jacket core spruce and the lace shape without visible paragraph in the coat to let pass In this case, however, would be at the core of the floor Sales arise, which is a predetermined breaking when the floor is mushroomed represents place so that the mushroomed flags could break.

By the previously described projectile designs according to the invention, a lead-free hunting projectile is achieved in which the press-in and frictional resistance in the barrel is reduced and brought to normal size by the hard jacket and the soft projectile core, and overloading and coppering of the barrel is prevented. The smooth outer wall without relief grooves also results in less air resistance and thus a lower drop in speed. Due to the equality of shape, weight, material and material hardness of different projectiles, but different reactions of these projectiles in the target, the same point of impact is achieved within one caliber, so that it is not necessary to fire the weapon again when changing the ammunition. All projectile types maintain their full weight when passing through the target, so that a shot is more likely. Also, the Fig. 1 and 2 is achieved by the division of the projectile into two or more sectors, reaction time and greater impact in the target in accordance with. The backcountry risk is relatively low for projectiles that split into sectors. The production of these projectiles by pushing the projectile core material into the tube of the casing material and at the closing turning process on an automatic machine is extremely simple and inexpensive. Also in the case of bullets with a hard projectile core, the relief grooves, in particular fine relief grooves, on the projectile core are of importance because this prevents overpressures and does not overstress the barrel. Also, in all of the above-mentioned projectile types, no excess pressures occur when firing through a tighter polygon.
