The .300 Norma Magnum is a .338 Norma Magnum case necked down to .308 caliber.[1] This cartridge was named .300 Norma Magnum to differentiate it from the .308 Norma Magnum designed in 1960. The United States Special Operations Command (SOCOM) has selected .300 Norma Magnum as their new Advanced Sniper Rifle Cartridge (2016). C.I.P. listed this cartridge in 2012 with a max pressure of 4400 bar.[2]References1. ^{{cite book|last=Barnes|first=Frank C.|title=Cartridges of the World|year=2012|isbn=1440230595|page=471|edition=13th|editor=Richard A.
