New Hampshire-based Sig Sauer recently picked up a nine-figure award from the U.S. Army Contracting Command for .300 and .338 Norma Magnum ammunition.
Announced by the Pentagon on June 7, the $157.3 million firm-fixed-price contract covers production of .300 Norma Magnum 215-grain M1163 ball ammunition and .338 NM 300-grain armor-piercing M1162 cartridges for the Army. Although not a standard round for most U.S. military small arms – that's reserved for 5.56 and 7.62 NATO along with the new 6.8 NGSW Common Cartridge – the Army and Marines are both using .300 NM and .338 NM in the MK22 Advanced Sniper Rifle program.
In Army service, the MK22 is replacing the service's existing Remington-made M2010 Enhanced Sniper Rifle, as well as the M107 .50 Caliber Long Range Sniper Rifle. Meanwhile, it will replace all legacy M40A6 and Mk13 Mod 7 rifles in the Marines' inventory.

The MK22 is a modular system that will be fielded with three separate calibers, .338 Norma Magnum, .300 Norma Magnum, and
7.62 NATO, with the user able to swap calibers through barrel changes based on mission operating environments. Above is
