This round was developed during early 1930s on request from Italian army, as a dedicated medium machine gun ammunition, to provide longer effective range and better lethality when compatred to 6.5mm and 7.35mm rifle ammunition. Only few models of machine guns were developed or converted from earlier systems to fire this cartridge, and it never was chambered in any type of rifle (at least, no mass-produced rifles in this caliber exist). It became obsolete shortly after the WW2, and is long out of production.
