Atomic Ammunition's .308 Win 175gr subsonic ammo turns suppressed .308 rifles into quiet training and practice platforms. The 175gr hollow point boat tail load stays below the sound barrier, preserves practical accuracy, and fits suppressed precision work at sane distances.
Subsonic Performance & Applications
The 175gr HP BT is a proven match-grade projectile that delivers excellent accuracy even at subsonic velocities. In suppressed .308 platforms, noise drops to 120-125 dB – hearing-safe and dramatically quieter than the 160+ dB of unsuppressed supersonic fire. The 428 ft-lbs of muzzle energy provides effective terminal performance for close-range applications, and the .308's universal availability means you can use the same rifle for full-power and subsonic loads by simply swapping magazines.
American-Made Components & Quality
Every cartridge is loaded with American-made components: new brass cases, precision-weighed Hodgdon powder charges, and match-grade 175gr HP BT projectiles. Hand-inspected for consistent performance. Atomic Ammunition – 100% American-made, no shortcuts.
Frequently Asked Questions
Will this cycle my semi-auto .308?
Subsonic .308 loads may not generate enough gas pressure to reliably cycle all semi-auto platforms. Works best in bolt-action rifles. For semi-autos, an adjustable gas block is recommended.
Is this ammo suppressor safe?
Yes. All Atomic subsonic loads are designed for suppressed firearms. The 1,050 fps velocity stays below the speed of sound.
Can I use my same .308 rifle for subsonic and supersonic?
Yes. Simply switch ammunition. No barrel or gas system changes needed for bolt-action rifles. Re-zero is recommended when switching.
Is the brass reloadable?
Yes. New boxer-primed brass, fully reloadable.
What is the minimum order?
Minimum order is 100 rounds. Bulk discounts on 200+ rounds.
