The 7.65×53mm Argentine, also known as 7.65x54mm Argentine rimless cartridge was developed for use in the Mauser Model 1889 rifle by Paul Mauser of the Mauser company. It is also known as 7.65 mm Argentine, 7.65×53mm Belgian Mauser or 7.65 mm Belgian (in the United States) and 7.65×53mm Mauser (in Belgium).

The 7.65×53mm R is a rimmed variant of the 7.65 mm Mauser cartridge. Ballistically it is comparable to the also rimmed .303 British cartridge.

Use and distributionEdit

At one time, the 7.65×53mm Argentine cartridge saw widespread use. It was used by:

Chambered weaponsEdit

Some of the rifles it was used in were the Modelo 1891, Argentine Modelo 1909 Carbine, Modelo 1908, Modelo 1910, the Fittipaldi machine gun and the Argentine FN Model 1949. In Argentinian military service, the cartridge was used from 1891 to the early 1970s in Mauser bolt-action military rifles, as well as a semi-automatic rifle, the FN FN-49, manufactured by Fabrique Nationale in Belgium.

This cartridge was loaded commercially by many manufacturers in the United States until about 1936.[1] Hornady is the only major U.S. ammunition manufacturer to still produce this cartridge. Sporting ammunition in this caliber is still loaded in Europe.[1] Norma, Prvi Partizan and Sako currently produce 7.65×53mm ammunition. Reloadable cartridge cases can easily be produced by resizing and trimming .30-06 brass and .303 British load data provides a useful point from which to work.
