The is still used by some Soviet machine guns, such as the and such as,.
15mm was also widely used by the Germans during WWII such as in the, and the British as well to a lesser extent in the 15mm version of the, which was used on armored cars and some light tanks.Since 20mm is the cutoff point where most nations switch from to, it has come to also generally be the cutoff point between weapons classified as a machine gun or a cannon. This varies, however. For example, in World War II, Japan classified any weapon over 11 mm as a cannon; thus, in Japanese records, their 12.7 mm aircraft gun is classified as an autocannon, as it used explosive shells to overcome its lower compared to American 12.7mm/ weapons. A machine gun does not fire shells, so historically a weapon that fires shells below 20 mm can be a cannon. An accurate description always mentions, in addition to caliber, whether the weapon fires bullets or shells.A small number of were produced in 20 mm and larger calibers.20 mm have an outside bullet diameter and inside barrel diameter of 0.787 inches (20.0 mm). Projectiles or bullets are typically 75 to 127 mm (3–5 in) long. Cartridge cases are typically 75 to 152 mm (3–6 in) long.
Many but not all 20 mm rounds have an explosive filling and detonating.As an example, the sniper rifle fires a 20×110mm 130-gram projectile at a muzzle velocity of 850 m/s. For a simple slug this gives a muzzle energy of 47 kilojoules.

Rounds, and a stick of computer memory.Like most cannon ammunition, armed forces typically use 20 mm caliber weapons against large targets, such as vehicles, buildings, or aircraft.
