Description

The utility model relates to ammunition, namely to sub-caliber bullets for smooth-bore hunting weapons.

Known subcaliber bullet "Impulse" for smooth-bore weapons, containing a housing placed in a sector container made of lead and including a head connected by a landing rod with a stabilizer on which the wad is fixed (patent RU 80226, p. 21.04.2008, op. 27.01. 2009).

The bullet has a high destructive ability, but it is prone to deformation when fired and ricochet when meeting an obstacle (branches, shrubs, etc.), which leads to a decrease in accuracy.

The closest analogue adopted for the prototype is a subcaliber bullet “PP” for smooth-bore weapons, containing a steel case located in a sector container, including a warhead connected by a landing rod with a stabilizer on which the wad is fixed (patent RU 97190, p. 05.17.2010 Op. 08/27/2010).

The bullet is resistant to overloads, retains its original shape and is stable in flight when faced with obstacles (branches, bushes, etc.), as a result of which a high accuracy of the battle is achieved. The bullet is quite light, has a high breakdown ability, but a small stopping effect.

The technical problem of the claimed utility model is the creation of a sub-caliber bullet for smooth-bore weapons, capable of providing a technical result, which consists in increasing the stopping effect and the striking ability of the bullet.

To solve a technical problem in the sub-caliber bullet for a smooth-bore weapon containing a housing located in a sector container, including a head connected by a landing rod with a stabilizer on which the wad is fixed, according to a utility model, the body is made of steel and equipped with a lead core enclosed in a head steel shell, open front.

The front surface of the head of the housing is made flat.

The parameters of the bullet of the claimed design are optimal to achieve the claimed technical result.

The lead core forms the optimal weight of the bullet, providing a sufficient amount of stopping power and the damaging ability of the bullet.

The use of steel bullets in the manufacture of the body with the formation of a steel shell protects the lead core from deformation and improves ballistics. The bullet does not deform when fired from arising overloads, does not deviate from the trajectory when passing through a small shrub, which also positively affects the bullet's striking ability and its stopping effect.

The implementation of the lead core open front provides a fairly effective punching and stopping action.

Making the front surface of the head part flat provides less rebound and greater stopping power.

The utility model is illustrated by drawings.

In FIG. 1 shows a subcaliber bullet for a smoothbore weapon, general view.

In FIG. 2 is the same, view A in FIG. one.

In FIG. 3 the same, section AA in FIG. 2.

In FIG. 4 is the same, view B in FIG. one.

The bullet comprises a housing 1, including a sub-caliber head part 2, connected by a landing rod 3 with a stabilizer 4, on which the wad 5 is fixed. The body is made of steel and equipped in the head part 2 with a lead core 6 enclosed in a steel shell 7. The lead core 6 is made open in front. The front surface 8 of the head part 2 of the housing 1 can be made of various configurations. In a preferred embodiment, the front surface 8 is flat. The housing 1 is placed in a sector container 9, which is made in the form of two detachable sectors 10 and 11. The container 9 is equipped with jumpers 12, 13 for interconnecting the detachable sectors 10 and 11. The stabilizer 4 is two cylinders of different diameters: the front 14 with a cylindrical hole for the landing rod 3. On the lateral surface of the rear cylinder 15 are made right-angled rectangular cross-section ribs 16, providing rotation of the bullet after going beyond the muzzle of the weapon, which is necessary to increase stability on the trajectory and flight. Pyzh 5 contains recesses (not shown in the drawing), the size and location of which corresponds to the size and location of the ribs 16 of the stabilizer 4. Pyzh 5 contains a shutter 17. Each detachable sector 10 and 11 is equipped with a centering half ring 18. The outer surface of the pyzh 5 is formed by a combination of a cylinder 19 in the front part and the truncated cone 20 at the rear, with the larger diameter directed towards the rear end 21. Thus, the rear part of the bullet with a cone-shaped surface forms the so-called "skirt", which at the time of the shot excludes a jerk of powder gases.

When charging a cartridge, the outer surface of the "skirt" fits snugly against the inner surface of the sleeve. In connection with this, to exclude the occurrence of a piston effect, the wadge housing 5 is provided with a groove 22 located on the outer cone-shaped side surface of the wad 5. The groove 22 is designed to allow air to escape when the bullet is inserted into the sleeve. At the same time, the small size of the groove 22, sufficient for air to escape, does not allow powder gases to burst during firing.

The bullet is used as follows.

A container 9 is installed on the housing 1 with stabilizer 4 and wad 5. When it is installed on the head part 2 of the housing 1, the jumpers 12 and 13 are stretched, and the container 9 is adjacent with the inner surface to the side surfaces of the head part 2 of the housing 1 and the stabilizer 4. The centering half rings 18 abut into the radial surface of the head part 2 of the housing 1. The container 9 becomes inseparable from the housing 1, the stabilizer 4 and the wad 5, and in this form is a single whole - a sub-caliber bullet for smooth-bore hunting weapons.

Next, take a cartridge case with an inserted capsule, gunpowder is poured into it, after which a bullet is placed in the cartridge case. At the same time, the presence of a groove 22 through which the air is released allows avoiding the occurrence of a piston effect when a bullet is installed in a sleeve.

At the time of the shot, the pressure of the powder gases pushes the bullet. At the same time, the presence of wad 5 of shutter 17 in the form of a recess, as well as a “skirt” of the rear part of wad 5, which is tightly adjacent to the barrel sleeve, prevent the breakthrough of powder gases. The exception of the breakthrough of powder gases provides a high initial velocity of the bullet, increasing the range and accuracy of fire.

At the time of the shot, as a result of overloads, the casing 1 is deposited on the stabilizer 4 and a slight deformation of the casing 1, including expansion. The pressure of the extended housing 1 on the container 9 leads to the rupture of the jumpers 12 and 13. Next, the bullet moves along the barrel of the weapon, while the container 9 protects the barrel of the weapon from damage, and also reduces friction when the bullet moves along the barrel. The presence of a steel shell 7 prevents the deformation of the head part 2 with a lead core 6 when fired. When the bullet exits the muzzle, under the influence of the incoming air flow, the parts 10 and 11 of the container 9 are separated, without interfering with the movement of the bullet along a predetermined path. The presence of a steel shell 7 prevents the ricochet of a bullet when passing through a small shrub.

In the manufacture of wad, stabilizer and container, high pressure polyethylene is used.

The inventive development of a sub-caliber bullet for a smooth-bore weapon combines the advantages of a bullet of non-deformable materials (steel, brass, copper) and a bullet of deformable materials (lead).

The parameters of the bullet of the claimed design are optimal to achieve the claimed technical result, which consists in increasing the stopping effect and the damaging ability of the bullet.
