14.5 × 114 mm

The 14.5 × 114 mm has 42.53 ml (655 grains H₂O) 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.

Cartridges use lacquered steel cases and percussion primers. Some countries also use brass cartridge cases. The propellant consists of {{convert|28.8|g|abbr=on}} 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:{{cite journal |last=Andrew |first=Martin |title=PLA Mechanised Infantry Division Air Defence Systems |journal=Air Power Australia |date=April 2012 |pages=1 |url=http://www.ausairpower.net/APA-PLA-Div-ADS.html#mozTocId278413}}

• DGJ02: APIDS-T cartridges use {{convert|45|g|abbr=on}} 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 {{convert|150|m|abbr=on}} and {{convert|200|m|abbr=on}} from the muzzle. It has a muzzle velocity of {{convert|1250|m/s|abbr=on}} and is quoted as being able to penetrate {{convert|20|mm|abbr=on}} of armour plate set at an angle of 60° at {{convert|1000|m|abbr=on}}.
• DGE02: APHEI cartridges weigh between {{convert|175|g|abbr=on}} and {{convert|188|g|abbr=on}}. At {{convert|1000|m|abbr=on}} it is quoted as having a 90 percent chance of being able to penetrate {{convert|15|mm|abbr=on}} of armour plate set at 30°. At {{convert|300|m|abbr=on}} after penetrating a {{convert|2|mm|abbr=on}} soft steel plate (representing an aircraft skin) it can further penetrate a {{convert|1.2|mm|abbr=on}} 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 addition, the Ukrainian "Horizon's Lord" sniper rifle fires a 12.7 × 114 HL round made by necking down a 14.5 × 114 mm cartridge case to accept a 12.7×99mm / .50 BMG bullet. In essence, the 14.5x114mm cartridge is the parent case for the 12.7x114 HL.{{cite web | url=https://www.msn.com/en-us/news/world/ukrainian-sniper-sets-new-world-record/ar-AA1kcbpw | title=MSN | website=MSN }}
