In addition, a sub-caliber cartridge is known, a cartridge is mounted in the sleeve for a bullet (shot), gunpowder and a capoul-water-filling gun (n). However, the bullet in that cartridge does not have an N-guiding kgpch-la, which leads to an additional rationalization when it is wiped away :.

the standard sleeve of which is placed a plastmass wound (yu-shaped, having a cylindrical yaw groove for installing a bullet with a dismeter, for example, 4-n, n-mm (1) When departing from a gun, the wedge separates from the bullet due to the electrodynamic resistance provided by grooves and protrusions The cartridge is suitable for firing with any small-caliber bullets of a smaller diameter than the diameter of the barrel. However, a plastic insert with a bullet reduces the speed of the bullet, although it gives a given direction to its movement. In addition, the insert is structurally difficult to implement, and the sleeve of a non-standard shape requires special processing to install a small-caliber bullet.

The objective of this utility model is to create a sub-frame cartridge of simple design, suitable for standard smooth-bore weapons of calibers 1S, 16, SO with a diameter of weapon barrels from 18.S to 15.5 mm or other calibers.

The technical solution to this problem is that the sub-caliber cartridge is equipped with a sub-cymbal metal barrel, in which the bullet is located in the central cylinder channel, the barrel flange is made to the size of the bottom of the cartridge case of standard calibres 12-20, and the cartridge has a plastic shell with an outer diameter equal to the diameter of the chamber of the weapon into which the metal barrel is pressed.

The industrial model is illustrated in the drawing, in which the cross section of the sub-caliber cartridge is assembled.

In the plastic shell 1, having the external dimensions of the chamber 12, 16, 20 or other calibers, a sub-cylinder metal barrel 2 with a through cylindrical central hole 3 of a small caliber (for example, 5.6 mm) with a cartridge chamber 4 for a small cartridge is pressed in /: У1iber cartridge 5. The barrel 2 is equipped with a flange 6 times MS-FU standard weapon shell and has a recess 7 for the location of the flange of the sleeve of a small caliber cartridge 5.

When firing a small-caliber bullet 5 with acceleration along the channel 3 of the small-caliber barrel 2, and then on the channel of the shotgun, acquiring additional acceleration.

The advantage of the utility model in comparison with the prototype is the increased accuracy of shooting, which is due to the guiding action of the barrel 2, and the increased speed of the bullet, the second one does not have any wads, inserts and other braking elements.

In the basic model, the dimensions of a standardized rifle cartridge with a length of bJ- / o mm can be used. Such a multiple-action cartridge, the size of which is in the hunter's cartridge, is simple in design; 11, it makes it possible to use both small-sized pyagrons of center battle and firing model charges from silt pellets when firing; buckshots of the corresponding dispenser, powder filling and capsule of NRK GB, ShZSh70, F42B 7/10, UNO.
