From Wikipedia, the free encyclopedia:
"The 7.65x53mm Argentine cartridge was developed for use in the Mauser Model 89 rifle by Paul Mauser of the Mauser company. It is also known as 7.65 mm Argentine, 7.65x53mm Belgian Mauser or 7.65 mm Belgian (in the United States) and 7.65x53mm Mauser (in Belgium).
The 7.65x53mm R is a rimmed variant of the 7.65 mm Mauser cartridge. Ballistically it is comparable to the also rimmed .303 British cartridge.
Interestingly, Fabrique Nationale, one of the world's major firearms developers and manufacturers, was established in 1889 in order to manufacture the 150,000 Mauser Model 89 rifles ordered by the Belgian Government.
\This cartridge was loaded commercially by many manufacturers in the United States until about 1936. Hornady is the only major U.S. ammunition manufacturer to still produce this cartridge. Sporting ammunition in this caliber is still loaded in Europe. Norma, Prvi Partizan and Sako currently produce 7.65x53mm ammunition."
