14.5×114mm

The 14.5×114mm has 42.53 ml (655 grainsH₂O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles, semi-automatic rifles, and heavy machine guns alike, under extreme conditions.

14.5×114mm maximum cartridge dimensions. All dimensions in millimetres (mm).

Americans define the shoulder angle at alpha/2 = 22.5 degrees. The common rifling twist rate for this cartridge is 455 mm (1 in 17.91 in), 8 grooves, ⌀ lands = 14.50 mm, ⌀ grooves = 14.95 mm.

According to the official guidelines the 14.5×114 case can handle up to 360 MPa (52,213 psi) piezo pressure. In C.I.P. regulated countries every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. pressure to be certified for sale to consumers.

• BS: Armour-piercing incendiary original anti-tank round. The projectile weighs 64.4 g (2.27 oz) and is 51 mm (2.0 in) long with a 38.7 g (1.37 oz) core of tungsten carbide^[1] with 1.8 g (0.063 oz) of incendiary material in the tip. The overall round weighs approximately 200 g (7.1 oz) and is 155 mm (6.1 in) long. The projectile has a muzzle velocity of approximately 1,006 m/s (3,300 ft/s) and can penetrate 30–32 mm (1.2–1.3 in) of RHA steel at an incidence of 0 degrees at a range of 500 m (1,600 ft), or 40 mm (1.6 in) at a range of 100 m (330 ft).^[2][3][4]
• B-32: Armour-piercing incendiary full metal jacket round with a hardened steel core. Projectile weight is 64 g (2.3 oz) and muzzle velocity is 1,006 m/s (3,300 ft/s). Armour penetration at 500 m (1,600 ft) is 32 mm (1.3 in) of RHA at 90 degrees.
• BZT: Armour-piercing incendiary tracer full metal jacket round with a steel core. Projectile weight is 59.56 g (2.101 oz) and muzzle velocity is 1,006 m/s (3,300 ft/s). Tracer burns to at least 2,000 m (6,600 ft).
• MDZ: High-explosive incendiary bullet of instant action. Projectile weight is 59.6 g (2.10 oz).
• ZP: Incendiary tracer round

Cartridges use lacquered steel cases and percussion primers. Some countries also use brass cartridge cases. The propellant consists of 28.8 g (1.02 oz) 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:^[5]

• DGJ02: APIDS-T cartridges use 45 g (1.6 oz) 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 150 m (490 ft) and 200 m (660 ft) from the muzzle. It has a muzzle velocity of 1,250 m/s (4,100 ft/s) and is quoted as being able to penetrate 20 mm (0.79 in) of armour plate set at an angle of 60° at 1,000 m (3,300 ft).
• DGE02: APHEI cartridges weigh between 175 g (6.2 oz) and 188 g (6.6 oz). At 1,000 m (3,300 ft) it is quoted as having a 90 percent chance of being able to penetrate 15 mm (0.59 in) of armour plate set at 30°. At 300 m (980 ft) after penetrating a 2 mm (0.079 in) soft steel plate (representing an aircraft skin) it can further penetrate a 1.2 mm (0.047 in) 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.
