Answering DrSchmittCSAEOD question, the Mauser 1909 was replaced by the argentine armed forces in 1954 by: first the belgian FN FAL in 7,62 x 51 caliber, according to the NATO standards of small weapons, and then by the DGFM FAL/FAP made under license by the “Domingo Matheu” military factory, so the 1891 and 1909 Mausers was used only for ceremonies and military parades.
Even the armed forces keep in their inventories large stocks of Mausers and their ammo, in 1978 during the crisis with Chile (Border Dispute) and in 1982 (South Atlantic war with the U.K.) the Mausers were pressed into service as second line weapons only for sentry duties, as Beleg correctly said.
Argentine hunters used until 1960, soft point ammo produced by the “San Francisco” military factory, later Norma ammunition in 7,65x54 (Yellow plastic tip) appeared in the market and become the favourite among them.
In the year 2000, the “Fray Luis Beltran” military factory begin the production of both FMJ and SP 7,65x54 ammo, this batch of ammo had Magtech primers and Hornady or Sierra bullets, another batch of ammo was produced by the same factory in 2008, and recently (2010), FLB launched into the market another batch of ammo both FMJ and SP.
It is interesting the demand of this caliber actually, not only FLB, but Ingman Konjic and Hornady also produced factory ammunition.
