Embodiment Construction

[0017]The armor-piercing projectile 1 comprises a cylindrical body 2 usually made of brass, light metal elements, plastics, etc., which is placed with clearance and in a predetermined position inside a case 13 having a corresponding size. The body 2 is inseparably attached to the casing 13 in a conventional manner, usually rolled or coated. During the production of body 2 its initial outer reference diameter is larger than when completed. At its rear (relative to the direction of movement of the cartridge 1 after being fired from the gun), preferably inside the cartridge case 13, the outer surface of the body 12 is provided with radial or helical cuts (usually one to three cuts). ). The cutouts 12 are spaced apart from each other by the guide surfaces of the cylindrical part of the body 2 of the cartridge 1 for guiding the cartridge 1 in the bore of the barrel for its rotation in the barrel. The cutouts 12 can be produced by various methods, such as cutting, rolling, extrus...

Abstract

The cartridge consists of a shell (13) with powder filling (16) and a bullet (1), where the bullet (1) comprises a body (2) having a rear base (6) and peripheral walls, in the axis of which is fixed a piercing core (3). The body (2) of the bullet (1) is adapted for controlled detachment, in the area of weakening of its peripheral wall, of at least one of its forward portion (5) and a rear portion (17) of greater diameter, corresponding to the calibre of the gun, for stabilising and guiding the bullet (1) in the gun barrel. The piercing core (3) is lodged with radial allowance in the body (2), in the opening (19) on the fron side. Between the forward portion (5) and the rear portion (17) of the bullet (1), the body (2) has a deforming wall (10) with reduced thickness, so that the area where it meets the shouldered rear portion (17) forms the ripper zone of the front portion of the body (2), while the piercing core (3) comes to point at its front end (8) and the hollow between this front end of the core (3) and the adjacent part of the inner wall of the opening (19) of the body (2) is filled with a malleable plug (4) whose outer surface forms at least the greater part of the impacting surface (20) of the bullet (1). The subject of the invention also involves a method of preparing at least one radial incision in the body (2) of the bullet (1) of the cartridge, during which the rear portion (17) of the body (2) is formed with a greater outer diameter with at least one radial incision (12) of trapezoidal section with symmetrical sides.

Description

technical field [0001] The present invention relates to a cartridge assembly with armor-piercing projectiles having enhanced penetration effectiveness against body armor and other ballistic shields, especially hard barriers such as armored vehicles, special glass and the like. Background technique [0002] Known for use in pistols, rifles, machine guns, etc. are burst ammunition in which the body or casing of the bullet explodes to a larger diameter upon attacking the barrier, thus producing a stronger effect on the barrier. This effect is influenced to a considerable extent by the speed of the bullet and the resistance of the barrier to the impact of the bullet. Arranging the front of the bullet in such a way as to obtain controlled expansion so that the blast of the body when the bullet impacts the barrier is more forced and at a lower velocity. The bullet body can be pre-provided with external transverse or longitudinal peripheral cuts (PCT application WO 00 / 79211, US pa...
