7.65×20mm Long
The 7.65×20mm Long was a straight, rimless cartridge used in the French Modèle 1935 pistol, as well as the MAS-38 submachine gun and the ETVS submachine gun.
Description
The cartridge was developed for the United States and secretly produced in quantity too late for its intended use during World [War I]. The United States scrapped the weapons built for the cartridge between the world wars. France adopted weapons for the cartridge and those weapons saw combat use; so the cartridge is best known by its French name.The French military were introduced to the cartridge when the US demonstrated the Pedersen device after the end of World War I in Le Mans and again when John Browning exhibited a carbine in the same caliber in 1920. The US.30 Pedersen cartridge used in the Pedersen device was the basis for the 7.65×20mm Long. The cartridge dimensions were identical, although Pedersen device cartridges were loaded with a slightly heavier bullet which achieved a velocity of in the longer barrel of M1903 Springfield rifles.
Remington Arms produced 65 million cartridges for the Pedersen device between 1918 and 1920. French 7.65×20mm Long ammunition was manufactured in quantity from approximately 1935 to 1960.
In 2019, Steinel Ammunition began producing new 7.65×20mm Long, making the ammunition available again.
