From the manufacturer

Atomic Ammunition Subsonic .300 AAC Blackout 220 grain Boat Tail Hollow Point Brass Cased Rifle Ammo 20 Rounds. 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 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.
