[0278] FIG. 17 shows side view of shell 2. The fore-part of the shell body 2 is made as a lancet section 23 with an acute end 24 which passes into a cylindrical part 25, which passes into an inclined surface 26 of the leading cylindrical part 29, which passes into the rear cylindrical part 30 with smaller diameter.

[0279] Inclined surface 26 is made at an angle 27 to the longitudinal axis 28 of the shell 2. Acute angle 27 has measure d27 which is equal to 30-45 to the longitudinal axis 28 of the shell body, as a result, rifling of ammunition in the weapon occurs in less vulnerable state.

[0280] The thickness T29 of the leading cylindrical part 29 is 0.122D, where Doutside diameter of the ammunition, which is 1.5-2 times greater than thickness T.sub.swcb of side wall at case bottom of traditional ammunition for small arms, where (T.sub.swcb=0.0520.078 D.sub.cb, where D.sub.cb is outer diameter at case bottom), that provides a great inertia of the shell heating.

[0327] FIG. 53 shows side view of mechanism and FIG. 54unit C on FIG. 53, FIG. 55unit C on FIG. 53. Removal of captured ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20 from bolt 88 with the help of extractor 95 is shown. When the captured ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20 is being removed, the lower part 113 of the front ledge 87 of the lock frame 86 passes along the rear horizontal platform 108 of the lower ledge 106 and bears against the beginning of the front inclined area 110 of the upper ledge 109 of the extractor 95.

Meanwhile, for mechanical extraction, inclined ledge 92 of firing pin 89 opens expanding ring 69 and firing pin 89 comes out of engagement with igniter block 4 and conical bushing 93 on bolt 88 gets a gap 115 with the rear end of ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20. During the magnetic extraction conical section 90 of firing pin 89 is beyond the magnetic extraction washer-marker of the igniter block 5, wherein the magnetized magnetic extraction washer-marker 71 toms off from the firing pin 89, and the conical bushing 93 on the bolt 88 gets a gap 115 with the rear end of the ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20. The thickness T115 of the gap 115 is equal to 0.2D, wherein Doutside diameter of the ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20. The gap 115 between conical bushing 93 of bolt 88 and rear part of the ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20 does not allow the rear end of the ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20 to engage the conical bushing 93 during ejection beyond the weapon, what provides reliability of the loading cycle, reloading cycle.

[0328] FIG. 56 shows side view of mechanism. The ejection of ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20 by extractor 95 from the weapon is shown. When the ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20 is ejected by the extractor 95, the lower part 113 of the front ledge 87 of the lock frame 86 passes along the front inclined area 110 of the upper ledge 109, passes through the upper ledge 109, passes along the upper horizontal area 111 of the upper ledge 109, and stops at the end of it. During mentioned process the extractor 95 vigorously rotates on the shaft 103 and ejects the ammunition 1 or 6 or 8 or 10 or 12 or 16 or 18 or 20 from the weapon by semicircular hollow 97.

[0329] During the mechanism work in semi-automatic or automatic mode the lower part 113 of the front ledge 87 of the lock frame 86 only reaches the front inclined area 99 of the extractor 95, thanks to that the extractor 95 does not work during the shooting. Extractor 95 works in extraction of ammunition only during manual reloading what improve the reliability of weapon work in general and the extraction in particular. The reliability of extraction is achieved as expanding ring 69 or magnetic extraction washer-maker 71 take part in extraction once during the ejection of the training ammunition 20 or once during the ejection of the ammunition 1 or 6 or 8 or 10 or 12 or 18, in which the misfire has occurred, and are very simple in construction. The expanding ring 69 can make up to one million opening-closing cycles until failure in operation occurs, the magnetic extraction washer-marker 71 will have been demagnetized during 15 years no more than 5% of the initial magnetization.

[0330] In order to make a shot with the help of the claimed caseless ammunition, it is necessary to have a caseless weapon, which must have at least such mechanisms as: rifled barrel with cartridge chamber, barrel box, bolt with obturator, firing mechanism with striker, hammer in cocked position, firing spring, trigger, spring-loaded sear.

[0331] Shot is made with the help of claimed caseless ammunition in such way: ammunition is inserted into cartridge chamber of caseless weapon and is locked by bolt with obturator, where the problem of gas obturation in the bolt is solved. When the trigger is pressed, the spring-loaded sear comes out of engagement with the cocked position of the hammer and the hammer vigorously rotates under the action of the firing spring and strikes the striker. Striker fires primer of igniter block in caseles ammunition by its pan, propellant ignites, gases of high temperature and pressure are formed during the ignition of propellant and igniter block, they force shell to fly out of the barrel, rifling, geting axial rotation of the shell which is needed for stabilization of shell flight. There is combustible washer-marker in front of the primer of igniter block and when the washer is being burnt, the released gases pushes the standard primer of igniter block out after the shell. Depending on the purpose, changing the shell, it is possible to achieve a wide variety of tasks in shooting; claimed for invention ammunition can be armor-piercing, tracing, training, etc. If the igniter block is non-combustible, a mechanism of the ejecting of the igniter block is necessary in the weapon.
