The cartridge case is a cartridge case from a 7.62x39mm cartridge, with a barrel re-integrated under a 9-mm bullet. The cartridge SP-5 is sniper round that is made with high accuracy and has a 16-gram shell bullet with a steel core surrounded by lead placed in a bimetallic shell. The steel core, to increase the bullet penetration, is placed in its nose section. The lead core gives the bullet the necessary mass and ensures its penetration into the grooves of the barrel.The bullet shape with a length of 36 mm provides it with excellent ballistic properties when flying at a subsonic speed.
The speed of a bullet when firing from a special sniper rifle VSS Vintorez or AS Val is 280-300 M/S muzzle energy is 600–700 J
The SP-6 cartridge is intended for shooting from AS Val and is a Assault round intended for hitting targets concealed in cars or protected by body armor. The SP-6 bullet has a mass of 16.2 grams and a steel hardened core. At the head of the bullet, the core protrudes from under the shell of the bullet that is, the half-shell bullet Due to its design, the bullet of the SP-6 cartridge has a stronger punching action than the bullet of the SP-5 cartridge.
The speed of a bullet when firing from a special sniper rifle VSS Vintorez or AS Val is 280–300 m / s. The muzzle energy is about 600–700 J, which is approximately twice the muzzle energy of the bullet of the 9-mm NATO cartridge, fired from the popular silenced submachine gun Heckler-Koch MP5SD variant
The bullet of the SP-6 cartridge is able to pierce an 8-mm steel sheet at a distance of 100m or hit a target protected by a bullet-proof vest level 2 and 3 at 300–400 meters.
The bullet of the PAB-9 cartridge, in contrast to the SP-6, does not have a rear centering girdle, the rear cone of the bullet is longer, the diameter of the core is slightly larger.The SP-6 and PAB-9 bullets also differ in the length and thickness of the lead shirt. As a result of such changes, the bullet and the PAB-9 cartridge itself have a more substantial mass, while the bullet's indicators of shooting accuracy worsen. The increase in the length of the leading part of the PAB-9 bullet could not but lead to an increase in the boost pressure and an increase in its initial velocity as compared with the cartridge SP-6. The bullet of the PAB-9 cartridge weighing 17 g develops an initial speed of over 300 m / s.
The cartridge was developed as a cheaper version of the SP-6. Bullet weight is higher and is 17 grams. After the development was widely advertised, however, the bulk purchases were limited to several batches. Currently, it is banned to use because of the higher pressure in the barrel of both VSS and VAL, which reduces the life of the weapon to about 3000 shots.
SPP (Blue tıp):
Developed in 2002 by order of the Tula cartridge plant as a replacement for the expensive and low-tech cartridge SP-5. The bullet of the SPP cartridge pierces a steel sheet 5 mm thick at a distance of 100 m. The steel sleeve is coated with a phosphate coating, the bullet head is painted blue
The SPP bullet consists of a bimetallic shell with a truncated tip and a combined core - a bare steel core at the head of the bullet and a lead core behind it. The “SPP” bullet provides breaking through of a 5 mm thick steel sheet made of steel of grade St.3 at a distance of 100 m or “6V23” body armor at a distance of 250 m.
The cartridge, designed to replace the "armor-piercing" SP-6. The bullet of the BP cartridge pierces a steel sheet with a thickness of 7 mm at a distance of 100 m. The steel sleeve is coated with a phosphate coating, the bullet head with a protruding steel core is painted black.
