In ammunition, today we will focus on the Belgian caliber cartridge 5,7 × 28 mm – pistol cartridge, created in 1986 to replace an already widespread cartridge 9 × 19 mm Parabellum NATO standard, although it bears little resemblance to the cartridge pistol. It is a compact cartridge with a pointed bullet and sleeve bottle-shaped, which, according to developers, has been obtained by replacing bullets and cartridge cases shortening 5.56 NATO. This round took place between intermediaries submachine pistol and ammunition. Compared with the chuck 9 × 19 mm, it provides a greater flatness of fire, smaller returns, greater effective range (the maximum range of a bullet – 1510 m and the maximum uboynaya- 825 meters, but because of the light bullets killing power of the cartridge falls rapidly at a distance of 600 m), armor piercing (with an initial velocity of 650 to 720 depending on the length of the barrel at a distance of 50 meters the bullet pierces the standard chuck 48 layers of Kevlar, and at a distance of 150-200 meters steel helmet or body armor standard set by NATO requirements CRISAT), as well as different degrees of reduced ricocheting. The main characteristic of the cartridge is enormous penetrating ability, which is an advantage compared with other pistol cartridge. Properties ballistics are that when released into the soft tissue, the bullet makes a turn of 360 degrees, and then continues its movement, stopping after 10 – 15 cm . This feature eliminates the departure bullet right through the human body, reducing the number of random victims to zero. In addition, the bullet causing fatal injuries of internal organs, internal and external bleeding and remains in the body. Typically, a single bullet to the torso / head enough to stop the enemy. Cases of death from shock. Sam cartridge designed specifically for the Belgian submachine gun FN P90, but it is also used in the PS90, AR-57, PP Singapore ST Kinetics CPW, VBR-Belgium CQBW gun FN Five-seveN. There are several types of the cartridge : standard (SS190), armor piercing steel core, tracer (SS196SR), subsonic (SB193: his bullet weighing 3.6 g is weakest killer stopped and the breakdown of the family from their patrons, as because of its low speed 305 m / s, the bullet does not change its direction in the tissue and can not be strong enough to break through the obstacles), single, expansive (SB195LF and SS197SR (?): has less penetrating ability than SS190, but the stopping power and great destructive power), increased speed with a hollow bullet poluobolochennye. Its characteristics caliber cartridge 5,7 × 28 mm superior to its main rival 4,6 × 30 mm, but the German and other delegations rejected the recommendation on the NATO standardizing cartridge 5,7 × 28 mm, resulting in that the standardization process of the cartridge in the NATO countries has been postponed.
