 With

The invention relates to the field of hunting munitions and is intended for firing from hunting rifles having rifled muzzle narrowing trunks (paradoxes).

A well-known paradox pool is comprised of a metal body with two guiding rails made integrally with the bullet body.

A disadvantage of the known bullet is that in the process of pressing the bullets leading along the skeves into the grooves, at the initial stage of the process, the moment of inertia of the bullet relative to its longitudinal axis is reduced to the skeleton leading, the first crashing into the grooves. The greater the speed of the bullet and the greater its mass, the greater the likelihood of the bullet being torn off the rifling, and, as a consequence, the stabilization of the bullet in flight is insufficient.

An object of the invention is to reduce the possibility of a bullet being torn from a rifle.

This is achieved by the fact that the metal body of the bullet is made of at least two separate sections, fixed along the axis of the bullet with the possibility of rotation of each section around the longitudinal axis relative to each other, and at least one leading juice is made on each section.

Figure 1 shows a pool, side view; figure 2 is a view of figure 1; Figs. 3-8 are possible embodiments of a bullet, cuts; Fig. 7 is an embodiment of a separate section, a cut.

The pool contains a head section 1 and subsequent sections 2 and 3c leading along the skies 4 (Fig. 1). The head section may be made with slots 5 (FIGS. 1 and 2). The individual sections of the bullet are assembled and fixed in height on a central shaft 6 having a head 7 on one side and a riveting end S on the other side (Fig. 3). The assembled sections are arranged one above the other. Instead of a riveting central rod, a bolt (screw) 9 can be used on which the sections of the bullet 1 and 2 are assembled and secured with a nut 10 (Fig. 4), or a locking section 11 made with a threaded socket is used instead of a nut (Fig. 5 )

A threaded connection of the sections between themselves is also possible (Fig. 8). In this case, each subsequent section is provided with a protrusion with

a thread 12 that is screwed into the threaded socket 13 of each previous section. When collecting individual sections using threaded connections (figure 4, 5 and 8)

the direction of the thread is preferably made so that when the head section is inserted into the grooves and rotated, the threaded joints are tightened. The pool can be executed in

a variant where, as a bonding element 17, a polymeric material, for example polyethylene, is used to fill the internal cavity of the bullet (Fig. 6). The housing sections may be bimetallic, where the housing of section 14 is made of hard metal, such as brass or steel, and the lead juice 15 is made of soft metal, such as lead, and soldered to housing 14 (Fig. 7). AT

depending on the required mass of the bullet, its speed and height, the pool can be executed with a different number of sections, but not less than Two, and at the same time at least one leading juice is performed on each section.

. .

The pool operates as follows. At the time of the shot, the pool passes along the barrel, centered with the guides along the skids 4. Entering the rifled bowel, the pool is successively cut into the grooves by the guides along its sections, and each section cutting into the grooves acquires an angular velocity and rotates relative to the subsequent section, still not pressed Y grooves. In this case, the moment of inertia relative to the longitudinal axis of the bullet, reduced to each leading juice when it is cut into the rifling, is accordingly reduced. In proportion to this decreases

and the torque needed to impart the required angular velocity to each section, which reduces the possibility of disengaging leading grooves from grooves. After passing through the rifled choke of all sections of the pool

leaves the barrel with the angular velocity necessary for stabilization in flight by rotation.

Reducing the possibility of bullet disruption from rifling makes it possible to increase how

the speed of the bullet, as well as its mass, by increasing the number of sections making up the bullet. Moreover, the execution of the head section with a recess 16 or with slots 5 further increases the damaging effect of the bullet beyond

account of deformations of its head section.
