.300 Norma Magnum
The .300 Norma Magnum (not to be confused with the .308 Norma Magnum) was introduced
in 2012 by Norma Precision A.B of Sweden.
It is basically a .338" Norma Magnum case, necked down from .338" caliber or .308"or 30 caliber
The .300 Norma Magnum generates energy levels over 4,400 foot pounds per squire inch, at
velocities over 3,000 feet per second.  
In 2016 the United States Special Operations Command (SOCOM) selected the .300 Norma
Magnum as their new Advanced Sniper Rifle Cartridge, making this a military cartridge
as well as sporting rifle cartridge.
