  • 7.65mm Longue CARTRIDGE NOTES:

    The 7.65mm Longue Pistol Cartridge was developed by Remington Arms in the early 19th century and closely resembles a 7.65mm Parabellum or 7.65mm Mannlicher cartridge in both case dimension and power in terms of velocity and muzzle energy. The 7.65mm Longue Cartridge was originally offered as the .30 Pedersen or .30-18 Auto in The United States where it was intended to be used in a converted M1903 Springfield Rifle and allow it to fire the shorter cartridges compared to the standard .30-06 Springfield cartridge of the time. The cartridge was eventually adopted by the French, who gave it the metric designation and used it in the French M1935 Pistol and MAS-38 Sub-Machine Gun.
