MINNEAPOLIS, MN - Alliant Techsystems (ATK) announced today that it has received a $49 million contract from the U.S. This new round utilizes a 62 grain open tip boat tail hollow point bullet with a lead core and reverse drawn copper jacket that creates an open tip.
It was engineered after the Marine Corp identified barrier penetration issues with the M855 round. NSN # 1305-0, designated as the MK318 MOD-0, this round was designed as a “barrier blind” round and has superior penetration and better ballistic stability when shooting through glass, car doors, and other barriers where lesser rounds might be deflected.
The new SOST round from Federal Cartridge was engineered for the United States Marine Corps as a supplemental/replacement round to M855 green tip with more desirable terminal characteristics.
