The HSM .338 ARC 300 Grain Boat Tail Hollow Point ammunition delivers serious subsonic performance for shooters and hunters who prioritize power and precision in a suppressed rifle. Subsonic ammunition travels at a velocity below the speed of sound (approximately 1125 feet per second), which reduces the noise signature of the firearm, especially when used with a suppressor. Chambered in the increasingly popular .338 ARC cartridge, this 300-grain hollow point boat tail round offers the terminal performance and flexibility that modern suppressed hunting and tactical applications demand.
The .338 ARC is intended for suppressed shooting, including tactical and hunting applications. The .338 ARC works especially well from a suppressed rifle, providing excellent stopping power while minimizing the muzzle flash and report when you fire a round. Hornady’s testing confirms effective performance on medium to large game out to 200 yards with subsonic loads—a critical consideration for hunters pursuing deer, hogs, and similar game with sound-suppressed setups. The boat tail hollow point design supports both consistent accuracy at distance and controlled expansion on target.
Each box contains 20 rounds of HSM ammunition, loaded with quality brass cases for reliable feeding and reloadability. The 300-grain projectile weight balances energy retention with practical subsonic velocities across common .338 ARC platforms, from short-barreled rifles to full-length hunting carbines. The .338 ARC functions flawlessly in the AR-15 platform, with standard Type 2 bolt faces making the transition practical and cost-effective for existing AR-15 owners. HSM’s subsonic .338 ARC delivers the quiet, hard-hitting performance that modern hunters and shooters demand.
