Hornady Frontier .300 Blackout 208gr FMJ Subsonic 200rd Case The Hornady Frontier .300 Blackout is a 208-grain FMJ subsonic load packed in a 200-round case, and it is available at Battlehawk Armory for suppressed training and range work. Published muzzle figures are 1,025 feet per second and 485 foot-pounds from a 24-inch test barrel. Brass cases, military-grade Boxer primers, and Hornady projectiles keep the load consistent for practice and function checks. The heavy full metal jacket stays below the speed of sound in most barrels, eliminating the sonic crack when used with a suppressor. The 208-grain weight supports stable flight and reliable feeding in short-barreled and standard-length .300 Blackout platforms. Non-corrosive construction and reloadable brass cases make the round practical for high-volume sessions. Frontier ammunition is American-made and built for everyday use across target, training, and suppressed applications. The 200-round case contains ten 20-round boxes, providing a practical volume for extended practice. Add the Hornady Frontier .300 Blackout to your collection at Battlehawk Armory today.
