Problems solved by technology
[0003] In the field of ammunition products, brass or steel is mainly used to prepare shell casings, but brass is heavy and has some potential risks, and for some blank or subsonic ammunition may also, when using brass Use some stuffing to fill the propellant filled space, but this can easily lead to clogging problems
[0004] Patent CN207439278U provides a rifle bullet, which uses the area law design concept, which makes the muzzle velocity of the rifle bullet low, resulting in a small muzzle sonic boom, thereby reducing the muzzle noise, but the rifle bullet is connected in one piece, It is inconvenient to disassemble, and they are all copper structures, which have great defects in use

Embodiment 1
[0032] Example 1 :Such as Figure 1-4 As shown, it includes a cartridge 2 and a metal base 1; the cartridge 2 has a cartridge body 21; the cartridge body 21 gradually forms an oblique shoulder 22 towards the front end; the oblique shoulder 22 is narrowed into a neck 23; the neck 23 is the most The outer end has a mouth 24; the main body of the cartridge 21 gradually forms an insertion part 25 toward the rear end; the insertion part 25 is connected with the metal base 1 by double buckles to form a physical interlocking structure;
[0033] The inside of the cartridge body 21 contains powdered propellant; the bullet 3 can be inserted into the mouth 24 of the cartridge case for subsonic ammunition after the propellant has been filled,
[0034] The insertion method of the bullet 3 is spin welding; the welded joint is a butt joint;
[0035] The transition area between the cartridge body 21 and the oblique shoulder 22 forms a shoulder transition area A28; the transition area betwe...

Abstract
The invention relates to an ammunition product with the IPC (International Product Classification) number of F42B12 / 04, in particular to a cartridge case for subsonic ammunition. The cartridge case is provided with a cartridge case main body; the medicine cylinder main body gradually forms an inclined shoulder towards the front end, and the inclined shoulder is narrowed to form a neck part; an opening is formed in the outermost end of the neck; the cartridge body gradually forms an insertion part towards the front end; the insertion part and the metal base are in double-buckle connection to form a physical interlocking structure; the thickness of the inclined shoulder and the thickness of the neck portion range from 0.05 mm to 0.4 mm. The cartridge case is made of a polymer material, subsonic flight of the ammunition product can be well achieved through the oblique shoulder and the special structural design, and the ammunition product made of the cartridge case has good flight stability.
