What is 7.65 argentine?

7.65 Argentine, also known as 7.65x53mm Argentine, is a rifle cartridge that was developed in the late 19th century for military use in Argentina. It was primarily used in the Mauser Model 1891 rifle, which was the standard issue weapon for the Argentine military at the time.

The cartridge features a rimless, bottleneck design with a bullet diameter of 7.92mm and a case length of 53mm. It typically fires a 139-154 grain bullet at a velocity of around 2,400 feet per second. The 7.65 Argentine round is considered powerful and accurate, making it suitable for long-range shooting and military applications.

Although the 7.65 Argentine cartridge was primarily used in Argentina, it saw limited use in other countries as well. It has since been largely replaced by more modern cartridges, but it is still used by some collectors and enthusiasts for historical firearms.
