The 6.5×52mm Carcano, also known as the 6.5×52mm Parravicini–Carcano or 6.5×52mm Mannlicher–Carcano, is an Italian military 6.5 mm (.268 cal, actually 0.2675 inches) rimless bottle-necked rifle cartridge, developed from 1889 to 1891 and used in the Carcano 1891 rifle and many of its successors. A common synonym in American gun literature is "6.5mm Italian." In American parlance, "Carcano" is frequently added to better distinguish it from the rimmed hunting cartridge 6.5×52mmR (U.S. version: .25-35 Winchester). Ballistically, its performance is very similar to that of the 6.5×54mm Mannlicher–Schönauer.
