Product Info for Atomic Ammunition Subsonic .300 AAC Blackout 220grain Boat Tail Hollow Point Brass Cased Rifle Ammunition
Atomic Ammunitions .300 Blackout 220gr subsonic ammo is tuned for suppressed AR-15 reliability. This 220gr hollow point boat tail load delivers dependable semi-auto cycling, consistent subsonic velocity, and the quiet shooting experience the .300 BLK platform was designed to provide.
The .300 Blackout is the king of suppressed semi-auto shooting, and the 220gr subsonic is its signature load. Atomics cycling subsonic reliably feeds, fires, and ejects in standard AR-15 gas systems without the need for adjustable gas blocks. With a suppressor, noise drops below 125 dB dramatically quieter than unsuppressed supersonic fire. The 538 ft-lbs of energy at the muzzle makes this an effective close-range option for home defense, and the match-grade HP BT delivers consistent accuracy at distances where subsonic shooting excels (inside 200 yards).
Every round is loaded with components: new brass cases (reloadable), precision-weighed Hodgdon powder charges, and match-grade 220gr HP BT projectiles. Hand-inspected for the cycling reliability that suppressed AR-15 shooters depend on.
