All medium calibre
Twenty-one line items sit in the armour-piercing family. Designations run 20 mm x 102, 20 mm x 110 and 20 mm x 110RB, 23 mm x 115, 23 mm x 152B, 30 mm x 165, 30 mm x 173 and 40 mm x 365, with the suffixes AP, AP-T, API, API-T, APHC-T, APFSDS-T, APHEI-HC and PELE. Every entry states a round mass and a muzzle velocity, nearly all add a projectile mass and an operating temperature band, and most quote a maximum gas pressure. Two records, 30 mm x 173 APFSDS-T and 30 mm x 165 PELE, are marked by the source as still in a development phase.

A 20 mm x 110 armour-piercing incendiary round for the 20 mm M55, HS 404 Hispano and HS 804 Hispano anti-aircraft guns, consisting of a brass cartridge case with percussion gun primer, propellant charge and an API projectile filled with incendiary composition.

A 23 mm x 115 armour-piercing incendiary tracer round for aircraft guns, made up of a brass cartridge case with a percussion gun primer, a propellant charge and an armour-piercing projectile filled with incendiary and tracer composition.
An armour-piercing incendiary round for the 23 mm ZU-23-2 and ZSU-23-4 antiaircraft guns, comprising a steel cartridge case with percussion gun primer, propellant charge and an incendiary-filled armour-piercing projectile.
23x152B mm armour-piercing incendiary tracer round, 189 g projectile at 970 m/s with at least 3.5 s tracer, for ZU-23-2 and ZSU-23-4 guns.

30x165 mm armour-piercing tracer round in the aircraft gun loading, 400 g projectile at 860 m/s with 3.5 s tracer.
30x165 mm armour-piercing tracer round in the autocannon loading, 400 g projectile at 970 m/s with 3.5 s tracer.
A 30 mm x 165 armour-piercing hard-core tracer round for the 2A42, 2A72 and 2A38M antiaircraft guns, with a tungsten carbide core giving double the penetration of older-generation armour-piercing projectiles.
A 30 mm x 165 round in an early development phase, consisting of a steel cartridge case with a percussion gun primer, propellant charge and a fragmenting armour-piercing projectile that acts as a penetrator with enhanced lateral effect.
A 30 mm x 173 armour-piercing round for the MK30-2 gun and the domestic 30 mm TA M12 gun, consisting of a steel cartridge case with percussion gun primer and booster, propellant charge and an armour-piercing projectile.
A 30 mm x 173 armour-piercing fin-stabilised discarding sabot tracer round, still in the development phase, whose sub-calibre tungsten alloy penetrator is launched by a lightweight discarding sabot, for the MK30-2 gun and the domestic 30 mm TA M12 gun.
A 30 mm x 173 armour-piercing high-explosive incendiary round with a hard-core penetrator and an impact base fuze with delay action, for the MK30-2 gun and the domestic 30 mm TA M12 gun.
A 40 mm x 365 round consisting of a brass cartridge case with a percussion gun primer, propellant charge and an armour-piercing projectile.
40x365 mm armour-piercing tracer round, 935 g projectile at 1025 m/s with 3 s tracer, for the 40 mm L/70 gun.
A 20 mm x 102 round with a brass cartridge case, electrical gun primer, propellant charge and an armour-piercing projectile, for the M621, M61A, M39 and M197 guns.
A schedule line names the cartridge designation first and the penetrator suffix second, so a buyer reads 30 mm x 165, APHC-T and then the figures. The comparable fields across these records are round mass, projectile mass, muzzle velocity and maximum gas pressure, with tracer burning time added on most of the tracer suffixes. Operating temperature limits close nearly every entry, and the guns named by the source appear where the record lists them.
Suffixes describe the documented projectile construction. AP and AP-T list a solid or tracer-carrying armour-piercing projectile, API and API-T add an incendiary composition, APHC-T records a tungsten carbide core, APFSDS-T a sub-calibre tungsten alloy penetrator with a discarding sabot, and APHEI-HC a hard-core penetrator with an impact base fuze. PELE describes a fragmenting penetrator with enhanced lateral effect.
Only the suffixes that record one. Most AP-T, API-T and APFSDS-T entries quote a tracer burning time, for example 3.2 s on the 20 mm x 102 AP-T and a minimum of 2 s on the 30 mm x 173 APFSDS-T. Plain AP and API entries carry no tracer line at all.
Yes, with their status stated. The 30 mm x 173 APFSDS-T record notes a development phase and the 30 mm x 165 PELE record an early development phase, and both are shown with the figures the source publishes rather than being held back from the schedule.
