• BS:
Armour-piercing incendiary original anti-tank round. The projectile weighs and is long with a core of
tungsten carbide with of incendiary material in the tip. The overall round weighs approximately and is long. The projectile has a muzzle velocity of approximately , giving it a translational
kinetic energy of and a
rotational kinetic energy of , assuming its nominal diameter of rather than the average diameter left behind by the rifling of - the range is between treating the cartridge as an
ellipsoid versus a cylinder for the purposes of
moment of inertia. Using the
rifled diameter yields . It can penetrate of RHA steel at an incidence of 0 degrees at a range of , or at a range of . • B-32: Armour-piercing incendiary
full-metal-jacket round with a
hardened steel core. Projectile weight is and
muzzle velocity is . Armour penetration at is of
RHA at 90 degrees. • BZT: Armour-piercing incendiary
tracer full-metal-jacket round with a steel core. Projectile weight is and muzzle velocity is . Tracer burns to at least . • MDZ:
High-explosive incendiary bullet of instant action. Projectile weight is . • ZP: Incendiary tracer round Cartridges use lacquered steel cases and percussion primers. Some countries also use brass cartridge cases. The propellant consists of smokeless powder with seven tubes, designated as "5/7NA powder". Two different versions of bullet series are known, the earlier has a conventional bullet jacket with a boat-tail. These have a long engraving portion that causes considerable barrel wear. The newer bullet types have a smaller engraving portion with a rounder boat-tail and were used from about 1957 onward. The cartridge has been manufactured in Bulgaria, China, Egypt, Hungary, Iraq, North Korea, Poland, Romania, Russia, and the former
Czechoslovakia. There are new Chinese armour-piercing types: • DGJ02: APIDS-T cartridges use tungsten penetrators, wrapped in discarding sabots (similar to the US military
SLAP cartridges) with dual colour tracers to aid ranging. The sabot splits and leaves the penetrator between and from the muzzle. It has a muzzle velocity of and is quoted as being able to penetrate of armour plate set at an angle of 60° at . • DGE02: APHEI cartridges are reportedly absurdly heavy, . At it is quoted as having a 90 percent chance of being able to penetrate of armour plate set at 30°. At after penetrating a soft steel plate (representing an aircraft skin) it can further penetrate a thick steel plate producing 20 fragments. Upon explosion between 75 and 95 incendiary pieces are formed which have an 80% chance of igniting aviation fuel. ==Chambered weapons==
