The Hornady Frontier .338 ARC 285gr FMJ Subsonic is a specialized, heavy-hitting cartridge engineered to deliver maximum stealth and superior terminal energy from the AR-15 and micro-bolt action platforms. As a subsonic load, it is specifically designed to remain below the speed of sound at 1,050 FPS, effectively eliminating the "sonic crack" when paired with a suppressor for an exceptionally quiet shooting experience. Despite its quiet signature, this 285-grain Full Metal Jacket bullet provides approximately 1.5 times the muzzle energy of subsonic .300 Blackout loads, offering ballistic performance comparable to a .44 Magnum but with significantly greater accuracy at extended ranges up to 200 yards. Packaged in a 20-round box, this Frontier offering utilizes military-grade brass, primers, and propellants to ensure the reliable cycling and consistent pressure required for tactical training, suppressed range practice, and close-range hunting.
