Argentine 7.65 x 53 mm Mauser with "S" Bullet Marking

Argentine factory loaded 7.65x53 mm Mauser SS cartridges with bullets marked “SS 60” (1960) and “SS 61” (1961) are not uncommon here, but here is a rare example with an “S” bullet marked “S 61”. Work was done at FLB using cases made between 1942 and 1953, although some remaning SS bullets from both years were loaded in cases made in 1962.
