The Hornady Frontier .300 Blackout 208gr FMJ Subsonic is a specialized, heavy-projectile load engineered for maximum stealth and reliable cycling in suppressed firearms. Produced at the Lake City Army Ammunition Plant, this cartridge utilizes a 208-grain Full Metal Jacket bullet designed to remain below the speed of sound, achieving a muzzle velocity of 1,000 FPS. By eliminating the "sonic crack" of standard supersonic rounds, it provides an exceptionally quiet shooting experience when paired with a suppressor, while still offering the heavy-hitting energy of a high-mass projectile. Packaged in a 20-round box, this Frontier offering is an ideal choice for tactical training, short-range target practice, and shooters who prioritize the unique, low-signature performance of the .300 Blackout platform.
