HSM 338 ARC subsonic ammunition pairs a 300-grain hollow point boat tail bullet with a subsonic velocity load designed to function reliably in suppressed and unsuppressed rifles alike. Built for shooters who demand consistency in the 338 ARC platform—whether you're running a short-barreled AR-pattern rifle for close-quarters work, suppressed hunting, or tactical training—this round delivers controlled performance without the supersonic crack. HSM has engineered this load to cycle reliably while keeping bullet energy and velocity in the subsonic range, making it an excellent choice for hearing-safe shooting without sacrificing downrange authority.
The 300-grain hollow point boat tail design promotes controlled expansion on impact while maintaining flight stability. This weight and profile pair naturally with modern 338 ARC rifles optimized for heavier projectiles, and the boat tail geometry enhances ballistic efficiency—especially useful when you're working with subsonic velocities where every grain of downrange energy matters. Whether you're handloading reference rounds or seeking factory ammunition that won't drift your zero when switching from supers to subs, HSM's subsonic load gives you a dependable platform.
Each box contains 20 rounds, and the case quantity (25 boxes) makes it practical for serious shooters building an ammunition stockpile. HSM ammunition is manufactured to exacting standards, so you can expect consistent case prep, primer seating, and propellant metering run to run—a foundation for reliable rifle performance whether you're drilling precision at distance or working in close.
| Cartridge | 338 ARC |
| Bullet Weight | 300 grains |
| Bullet Type | Hollow Point Boat Tail (HPBT) |
| Muzzle Velocity | 1050 fps |
| Muzzle Energy | 735 ft-lbs |
| Rounds Per Box | 20 |
| Boxes Per Case | 25 |
| Total Rounds Per Case | 500 |
| Manufacturer | HSM Ammunition |
This ammunition is chambered in 338 ARC and will function in any rifle properly chambered for that cartridge. Always verify your rifle's chamber marking before loading.
Subsonic rounds travel below the speed of sound (roughly 1125 fps), eliminating the supersonic crack even from unsuppressed fire. This makes them ideal for hearing-safe shooting, suppressed use, and applications where noise signature matters. You'll also experience less recoil and report, which can be beneficial for training and practice.
Each case contains 25 boxes of 20 rounds, for a total of 500 rounds. This bulk quantity is designed for shooters who practice regularly or build ammunition reserves.
Yes. HSM engineered this subsonic load to cycle reliably in properly functioning 338 ARC rifles regardless of whether a suppressor is attached. Always verify your specific rifle cycles the ammunition reliably before relying on it for hunting or duty use.
