Description

The invention relates to the field of round-bore ammunition, and in particular to wad containers for containing shotgun and bullet shells, which are intended to increase the accuracy of firing and facilitate the loading of rounds.

The aim of the invention is to improve the accuracy of fire and increase the tightness of cartridges.

The wad container is also a body in the form of an H-shaped cuff made of an elastic material, for example, high-pressure polyethylene.

The housing contains the head 1 and tail. 2 parts separated by a bottom 3.

In the head 1 part, a recess 4 is made on the upper end face O, on the walls of which. QQ formed longitudinal stiffeners 5, Qs and at the bottom, an asymmetric protrusion 6.

The outer side surface 7 of the head part 1 at the level of the upper end recess 4 is made expanding conical in the direction of the shot with a diameter D.

The tail part 2 has an outer centering juice 8 from the outside, the diameter d of which corresponds to the caliber of the used weapon, and from the end there is a recess 9, the cavity of which can be made shaped in the shape of the bullet head. The diameter of this cavity is made according to the diameter of the bullet, and its

depth corresponds to the height of the shot column or the length of the bullet.

Between the head 1 and the tail 2 parts, a bottom 3 is made, towards which the tail part narrows. The diameter of the smallest cross-section of the narrowing of the tail is equal to the diameter of the muzzle narrowing of the barrel of the weapon used.

The parameters of the conical lateral surface 1 of the stiffening ribs 5 are set from the condition that the requirements of the wad-container clamps to the sleeve channel and the elasticity of the wad elements depend on the caliber of the cartridge.

When equipping the tail cartridge 2, a part of the wad container is inserted into the sleeve channel and brought into contact with the bottom of the cavity 9 with the bullet and shot shell.

With this movement, the pool enters the cavity and is based on the walls of the wad container, and the shot is rebuilt, and the shot shell takes the form of the cavity of the tail of the wad container. The pool or shot is separated from the sleeve by the wall of the wad container.

At the same time, the conical lateral surface 1 under the influence of the sleeve is shaped and tightly pressed against its walls, reliably fixing the bullet or shot in its original position and creating the effect of forcing during firing. This is facilitated by the wedging effect of the bullet and shot on the walls of the recess 9 of the rear part, as a result of which the centering juice 8 is pressed against the sleeve.

When fired, gunpowder gases act on obturating wads, which press on bullet and shotgun shells and move them along with the wad container.

When considering the operation of the wad-container in the barrel, one should distinguish between the cases of its use;

firing from a conventional weapon barrel (FIGS. 5 and 8);

firing from an extra barrel while moving along the cylinder-conical channel of an extra barrel (Figs. 6 and 9);

firing from an extra barrel during movement along the channel of the carrier barrel of an extra barrel (Figs. 7 and 10).

In the case of firing from the main barrel, the wad container is guided in the channel by both the head and tail. In this case, the contact area will be the largest in comparison with other cases of using the wad container.

When passing the muzzle narrowing, the wad-container additionally deforms, shaping the shotgun. However, due to the fact that the hardest part of the wadding container is the bottom, the bottom has a critical cross-sectional size equal to that of the muzzle narrowing, shot

In this case, the projectile is only elongated along its length, and its head part remains unchanged. The fraction interacts with a muzzle narrowing through a wad container. The character of the interaction is soft, close to unstressed. This effect is especially noticeable when shooting from trunks with short round check constrictions.

Similar advantages are obtained when shooting a bullet using the proposed wad-container. In this case, the element that is deformed when the muzzle bullet passes through is the walls of the tail section.

In case of firing from inset barrels

the wad container is guided in the channels by the ends of the head and tail. The gap between the walls of the barrel and the wad-container in the head is selected due to the elasticity of the conical surface, and in

the tail part due to an increase in its diametrical dimensions due to the impact on the inner surface of the recess of the grains, obturating wad and powder gases.

After leaving the barrel, the conical surface of the wad-container expands and assumes its initial position as protruding above the wad part, which is affected by powder gases flowing out at a much higher speed than the shot shell.

As a result, the wad container receives additional acceleration and is separated from the shot shell and bullet.

At the same time, due to the influence of the incoming air flow on the inclined plane, as well as the asymmetry of the location of the reflecting protrusion, the wad overturns and moves it away from the direction of flight of the shot projectile.

The movement of the wad container is slowed down and the shotgun can easily overtake it.

Similarly, separation from the wad-container and the bullet occurs.

Thus, the implementation of the proposed technical solution allows, in comparison with the prototype, to accurately base shot and bullet shells during their movement along the barrel channel both when firing from a conventional barrel a rifle, and using extension barrels.

Maintaining a shotgun shell house wadder-container reduces the impact of the shot on the muzzle narrowing, makes the process of concentration shotgun and it is smooth, less shock, which ultimately reduces the deformation of the shot and increases the accuracy of fire.

In the case of using a bullet, it is possible to dispense with the guiding elements that are destroyed when passing the muzzle narrowing.

The adopted scheme allows the use of the proposed technical solution for steel shot cartridges.

The large surface of the mutual contact of the surfaces of the sleeve and the wad-container reduces the likelihood of moisture penetrating into the sleeve.

Tests of prototype cartridges equipped using the proposed wad-container confirmed that there was an improvement in the accuracy of firing with a shot and a bullet (ball) at ranges over 40 m, which exceed the requirements for standard hunting cartridges. -There was an improvement in accuracy and when using loose trunks.
