The 14.5 × 114 mm has 42.53 ml (655 grains H 2 O) 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 × 114 mm maximum cartridge dimensions. All dimensions in millimetres (mm), but angles may be measured in degrees or degrees-arcminutes-arcseconds (°); alpha is 22.5°. Americans define the shoulder angle at alpha/2 = 22.25°. The most common rifling twist rate for this cartridge is 1 in, with 8 grooves, land ⌀, and groove ⌀. Assuming a muzzle velocity of, as is roughly typical for it, this gives it a muzzle angular frequency of ≈ (&nbsp). According to the official guidelines, the 14.5 × 114 mm 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.

• Illustration — B-32 API projectile on the left, hardened steel core aside. Tip is black with a thin red band below. On the right, BZT API-T projectile with dark red tip and a wide red band below; hardened steel core and tracer cup on its right. Both jackets and the tracer cup are made from copper-washed steel. Between the cores and the jackets there is a layer of lead. • Illustration — Dummy round • Illustration — 14.5 × 114 round with a US 1 dollar bill for reference • Illustration — Seven rounds of 14.5 × 114 made in 1981, with a $1 bill for reference • Illustration — 14.5 × 114 Soviet ammunition base, made in 1981 • BS: Armour-piercing incendiary original anti-tank round. The projectile weighs 64.4 g and is 51 mm long with a 38.7 g core of tungsten carbide with 1.8 g of incendiary material in the tip. The overall round weighs approximately 200 g and is 155 mm long. The projectile has a muzzle velocity of approximately, giving it a translational kinetic energy of ftlb and a rotational kinetic energy of ftlb, 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 ftlb. It can penetrate of RHA steel at an incidence of 0 degrees at a range of 500 m, or 40 mm at a range of 100 m. • B-32: Armour-piercing incendiary full-metal-jacket round with a hardened steel core. Projectile weight is 64 g and muzzle velocity is 1006 m/s. Armour penetration at 500 m is 32 mm of RHA at 90 degrees. • BZT: Armour-piercing incendiary tracer full-metal-jacket round with a steel core. Projectile weight is 59.56 g and muzzle velocity is 1006 m/s. Tracer burns to at least 2000 m. • MDZ: High-explosive incendiary bullet of instant action. Projectile weight is 59.6 g. • 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 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 150 m and 200 m from the muzzle. It has a muzzle velocity of ft/s Mach and is quoted as being able to penetrate 20 mm of armour plate set at an angle of 60° at 1000 m. • DGE02: APHEI cartridges are reportedly absurdly heavy,. At 1000 m it is quoted as having a 90 percent chance of being able to penetrate 15 mm of armour plate set at 30°. At 300 m after penetrating a 2 mm soft steel plate (representing an aircraft skin) it can further penetrate a 1.2 mm 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.

In essence, the 14.5 × 114mm cartridge is the parent case for the 12.7 × 114 HL.
