Abstract

The utility model relates to ammunition, in particular, to bullet cartridges for smooth-bore guns, both with and without Lancaster drilling, and can be used for sports shooting and shooting when hunting large animals (wild boar, moose, wolf, etc.). The cartridge contains a bullet 1 (short or oblong) and a sleeve 2 with a length L. The sleeve is bottle-shaped and has a body 3 with a length l, a datch 4 of diameter d and a slope 5 with a length l and with a diameter of shoulder D. The length of the dult is determined for reasons of durable mounting of the bullet. The dimensions L, l, l, D and d are chosen from the conditions for increasing the reliability of the operation of smooth-bore weapons and increasing their operational characteristics.

Description

The utility model relates to ammunition, in particular, to bullet cartridges for smooth-bore guns, both with and without Lancaster drilling, and can be used for sports shooting and shooting when hunting large animals (wild boar, moose, wolf, etc.).
Known cartridge for smooth-bore rifles with a divided powder charge with a Poleva-6 bullet (Kislin MA Bullets fly far and accurately when firing Iskra-M cartridges. They hit powerfully. Magazine Hunter’s Arsenal M., No. 7, 2006) .
The known cartridge contains a sleeve, a primer-igniter, a main propellant charge, a wad, which has recesses for accommodating part of the stabilizer together with stabilizing protrusions, and a metal bullet. The bullet is equipped with female centering separating elements, and a stabilizer is installed on its shank. The head part of the bullet is made with a cylindrical tail part, and the stabilizer is mounted on the tail part of the bullet with tension. In the cartridge case there is an additional part of the propellant charge, separated from the main propellant charge by a diaphragm with a hole.
The disadvantage of the known cartridge is the complexity of the design and the low speed of a bullet shell. The low speed of a bullet shell degrades the damaging properties and reduces the accuracy of firing, which is caused by the high magnitude of the advancement of firing at fast-moving targets.
Known cartridge for smooth-bore rifles of the company BFS Sauvestre France (Article "The bullet of the Soviet is now in Russia", the magazine "Kalashnikov, weapons, AMMO, EQUIPMENT, No. 2, 2000), containing a sleeve, primer-igniter, propelling charge and subcaliber swept bullet projectile. The projectile contains a composite container, which separates when the bullet projectile departs from the barrel, and the plastic tail, immersed in a projectile charge and protruding from the composite container.
The well-known bullet cartridge has a complex structure and has a relatively low initial flight speed of a bullet shell (500-580 m / s), which is significantly inferior to the initial velocity of the bullets of cartridges to rifled long-barreled hunting rifles, which is at least 750 m / s.
To obtain a license for rifled weapons (cartridges for which have high ballistic characteristics), a five-year experience in possession of smooth-bore weapons is required. Therefore, there is a need to improve the ballistic characteristics of cartridges for smooth-bore guns. The main direction of improving smooth-bore cartridges is to increase their ballistic characteristics by increasing the initial (muzzle) bullet flight speeds. For this, a Lancaster drill is used - an oval-screw drill of a barrel bore weapon, stabilizing the projectile (bullet) by rotation.
Known bullet cartridges for smooth-bore weapons 9.6 / 53 and 366 Lancaster (yandex.ru ammunition 9.6 and 366 Lancaster). The cartridges of these calibers are developed on the basis of domestic combat cartridges - 7.62 mm rifle (7.62 × 54) and 7.62 mm automatic (7.62 × 39), respectively. These cartridges contain a metal sleeve and a shell bullet, which are stabilized on the trajectory by rotation, acquired through a special design of the barrel bore. These cartridges use short bullets with an oval head, and the sleeves have a low bottle-to-bottle ratio, which is the ratio of the average internal diameter of the sleeve to the caliber.
The disadvantage of the known cartridges caliber 9.6 and 366 Lancaster, taken as a prototype, is that their use reduces the reliability of the operation of the weapon itself, worsening the conditions of its loading, unloading and extraction. In addition, the use of short bullets with an oval head reduces the accuracy and accuracy of the battle.
The objective of the utility model is to improve the reliability of the operation of smooth-bore weapons and improve its operational characteristics.
The task is solved by the fact that in a bullet cartridge for smooth-bore weapons, containing a cartridge-fitted cartridge igniter and a bullet fixed in the cartridge case, the length of the cartridge case, the length of the shell slope, the length of the cartridge case, the diameter of the arm and the diameter of the cartridge case satisfy the following ratios:
1.28≤D / d≤1.35;
1.28≤L / (l 1 + l 2 ) ≤ 1.32;
1.14≤ (l 1 + l 2 ) / l 2 ≤1.17,
where L is the length of the liner;
l 1 - the length of the slope;
l 2 - the length of the liner body;
D is the diameter of the sleeve sleeve;
d is the diameter of the sleeve.
The claimed utility model has a simple design that allows the use of these cartridges, both for conventional smooth-bore weapons, and for smooth-bore weapons with a drilling Lancaster. At the same time, the shape and dimensions of the liner increase the reliability of the functioning of the weapon, namely, they facilitate the extraction and improve the loading conditions. Improve and
performance characteristics. Accuracy of shooting increases, and the speed of a bullet of a declared cartridge approaches the speed of bullets of cartridges to rifled long-barreled hunting rifles. In the claimed cartridge can be used not only a short bullet with an oval head, as in the prototype, but also an oblong bullet that has better (compared to short bullets) ballistic characteristics. Oblong bullets have a higher flight speed and higher energy, and the flight path of such bullets is more flat (sloping), which increases the accuracy and accuracy of shooting. In addition, the design of the claimed cartridge allows you to use it for smooth-bore weapons of small calibers, thereby eliminating the possibility of ricochets when shooting in hunting conditions and increasing the safety of using weapons.
The utility model is illustrated in the drawing, which shows a bullet cartridge for smooth-bore weapons.
The cartridge contains a bullet 1 (an elongated bullet is shown in the drawing) and a sleeve 2 of length L, equipped with an igniter capsule (not shown). The sleeve is bottle-shaped and has a body 3 with a length l 2 , a dulce 4 of diameter d and a slope 5 with a length l 1 and with a diameter of shoulder D. The body 3 serves to accommodate a powder charge.
Bullet 1 is securely fixed in Dultz 4 by any known method (for example, by centering, running in or crimping). The length of the collet is determined for reasons of durable fastening of the bullet. Sizes l 1 , D and d of slope 5 (transition section from Dultz to body) are chosen from the conditions for increasing the reliability of operation of smooth-bore weapons and increasing their operational characteristics.
