    Cartridge for a pistol
    The invention relates to a cartridge for pistols with a cartridge case, a primer placed in the bottom of the case, a powder contained in the interior of the cartridge case and a projectile that sits snugly in the cartridge case and protrudes beyond the sleeve edge. Pistols are self-loading pistols and submachine guns with different barrel lengths to understand. For pistols are different caliber (diameter of the projectile) in use. Widely used are cartridges with cylindrical sleeves in the caliber 9 millimeters or bottle-necked sleeves in the caliber of 7.62 mm.
    The most widely used in the 9mm caliber class are the cartridges 9x19 (Lu-ger), 9x21, 9x18 (Makarow) or 9x17 (9mm Browning court) and in another caliber 7,62x25 (Tokarev). The aforementioned caliber designations comply with the regulations of the "Commission Internationale Permanente pour l'Epreuve des Armes a Feu Portatives" (C.I.P.). The names of the manufacturers in parentheses are protected trademarks. C.I.P. specifies that for pistols in caliber 9x19, the total length of one cartridge must not exceed 29.69 mm. Magazines for such cartridges are housed in the handle of a gun, the handle of normal sized hands can be well embraced.
    Last but not least, the balance of the 9x19 cartridge in terms of size, caliber and performance has made it the most widely used cartridge in the world.
    It is charged with a fast-burning powder and accelerates a bullet of about 8 grams of mass to 350 to 370 m / sec ("V °"), at a gas pressure of 2500 to 2700 bar.
    The cartridge 7.62x25 (Tokarev) has a total length of 35mm according to CIP and accelerates a bullet with 7 grams of mass to 430 m / sec ("V °"), at a gas pressure of 2300 bar. This cartridge has a very high penetrating power , but is for pistols in which the cartridges are in the handle, due to their length of 35 mm and the thus significantly increase handle size, especially in double-row magazines, not for normal sized hands sufficiently well to include.
    In general, it is desirable to achieve maximum effect with a pistol as compact as possible. The effect is measured in terms of the energy content of the accelerated cartridge in joules and depends primarily on the square of the running exit speed and on the mass of the projectile.
    In AT 511979 there is shown a cartridge with a known Tokarev sleeve, a brass bullet between 4-5 grams, a powder amount of 9-11 grams, a mean velocity of 545 m / s, a gas pressure of 2539 bar and a projectile energy of 691 joules , Although the cartridge achieves very good values, it is disadvantageous that the powder space is limited by the bullet shape.
    Therefore, it is an object of the invention to provide a cartridge which exceeds the performance of the cartridge of the cited application and the powder space is increased without changes to the sleeve. Furthermore, the new cartridge to be created in each magazine for cartridges of caliber 9x19 use, and beyond - only after the exchange of the barrel - can be fired.
    According to the invention this is achieved in that the known cartridge case in caliber 7,62x25, ie sleeve length 25mm, aufhimmt a projectile, which protrudes only so far out of the cartridge case that the total length of the cartridge the maximum C.I.P. The size of the bullet is between 2.90 grams and 3.99 grams, the diameter of which is 7.82 mm, and the powder space of the cartridge case contains 12-14 grains of a slow-burning powder, and the projectile has a cavity towards the powder chamber, which additionally allows the intake of powder.
    In-depth tests have shown that with such a combination of projectile and sleeve running exit speeds of 620 to 700 m / s, a tremendous penetration and energy output can be achieved in the target, the gas pressure remains at a relatively low level. This is explained by the fact that the extended powder space and the relatively light projectile is accelerated by a slowly burning powder over the entire length of the barrel and thus reaches a high running exit speed under moderate pressure. The light and relatively short bullet considerably reduces the recoil. For the most common run length of 4 to 6 inches (105-150 mm), a powder charge of 12 to 14 grains gives the best values.
    The preferred tuning of the inventive cartridge results in a bullet made of copper or brass with a weight of 3.05 grams and a powder of 14 grains of the conventional powder Accurate number 7. The average value of the gas pressure is 2586 bar. See the official documents of the Beschussamt Vienna.
    It is in the characteristics of the well-known and selected cartridge case 7,62 x 25 Tokarev, that its bottom matches the thrust base and the extractor claw for the larger caliber cartridge 9x19.
    The projectile itself may be concave, slightly convex or truncated cone-shaped and made of different materials within the scope of the inventive dimensions. It is advantageously made of brass or copper, which is given preference over lead shot because of the lower specific weight and hardness.
    In the following, the invention will be described and explained with reference to an exemplary embodiment with measured values and pictorial representations of the cartridge according to the invention. They show:
    1 shows a longitudinal section through a cartridge according to the invention,
    2: longitudinal section of the projectile,
    In Fig. 1, a cartridge case is summarily denoted by 1 and a fit in her perfectly fitting projectile. The cartridge case 1 is formed of a solid sleeve bottom 3 and a sleeve wall 10. The sleeve bottom 3 has an all-round Ausziehrille 4 and on its rear end face 7 a conventional primer 5, which communicates via a channel 8 with a powder chamber 9 in connection. The sleeve wall 10 is constricted to the front to an edge region of smaller diameter bottle neck. In this border area the projectile 2 is inserted accurately. The projectile 2 has a diameter of 7.82 mm and a powder space 9 towards open cavity 13, on. The
    Powder 15 low burning rate is located in the filled powder chamber 9 and also partially in the cavity 13 of the projectile 2. The front side 14 of the projectile 2 is slightly convex. Basically, the outer bullet shape can be made different. It is preferably made of copper or brass and has a mass of 2.90-3.99 grams.
    The outer diameter of the cartridge case 1 corresponds to that of a cartridge of larger caliber, so that Ausziehrille 4 and the rear end face 7 fit to the bottom and the Ausziehkralle a pistol for a larger caliber.
    In Fig. 2, the projectile according to the invention 2 is shown separately in longitudinal section. It is the cavity 13, which can additionally serve as a powder chamber 9, and the partition wall 18, 19 to the powder chamber 9 and the outer diameter 17 of the projectile 2 shown.
    The preferred cartridge was tested at the Vienna Fire Department. The total length of the cartridges submitted there was 29.65 mm, just below the maximum allowed length. It was filled with 14 grains of a commercial powder of low burning rate. The powder "Accurate No 7" of the US company Western Powers Ine was used. The bullet had the shape of the invention and a weight of 3.05 grams. The bombardment took place with a 150mm long run of the Beschussamt Vienna.
    Means from the values measured at seven shots scattered only minimally, they are:
    Gas pressure: 2586.7 bar
    Speed: 694.64 m / sec. Energy: 735.87 joules
    For comparison, a 9x19 caliber cartridge achieves a projectile energy of 380 joules.
    Overall, with the cartridge of the invention, the effect of larger cartridges is reached and exceeded and it requires no heavy weapons to control them.
