The Remington UMC .308 Winchester 150-grain Full Metal Jacket (FMJ) Brass 20-round box is a centerfire rifle cartridge engineered specifically for high-volume range training, tactical drills, and baseline zeroing across .308 Win and 7.62x51mm NATO rifle platforms. A common friction point with bulk training ammunition is inconsistent cycling and wide velocity spreads that cause erratic point-of-impact shifts in semi-automatic rifles. Remington addresses this training limitation by combining a smooth FMJ bullet geometry with controlled assembly tolerances, delivering dependable chambering, smooth extraction, and predictable downrange flight.
The primary technical advantage centers on a 150-grain full metal jacket bullet featuring a solid lead core enclosed in a hard copper-alloy jacket. This non-expanding profile reduces lead and copper fouling in the bore while maintaining a uniform bearing surface for shot-to-shot consistency. Sporting a 0.314 G1 ballistic coefficient, the bullet resists drag to maintain stable trajectories through typical training distances. Additionally, Remington’s Kleanbore non-corrosive Boxer primers deliver clean, instant ignition without leaving harsh, barrel-degrading residue behind.
Exiting the muzzle at a velocity of 2,820 FPS, this 150-grain load generates stable cycling energy to reliably operate gas-operated semi-automatics (such as AR-10, M1A, and FAL variants) as well as bolt-action rifles. Assembled in precision-drawn, reloadable virgin brass cases, it ensures uniform chamber pressure curves and smooth extraction during extended firing sessions. It serves as an ideal, cost-effective option for marksmanship practice, tactical rifle training, and high-volume target shooting.
Key Benefits
