Product Description

300 AAC Blackout (300 BLK) 220 Grain Total Metal Jacket Round Nose Ammunition Subsonic

500 Rounds

This 300 AAC Blackout 220 Gr Subsonic is manufactured in the USA using .3083 diameter “TMJ” Round Nose heavy copper plated ultra-hard lead-antimony core projectiles. We use once-fired military/ police brass, which is acid washed and processed to SAAMI specifications and electromagnetically inspected to ensure safe internal tolerances.

In our loading process we only use the top quality SMP powders and ATK primers. Powder is dropped to +/- 0.1 grain accuracy to ensure the highest performance. Cartridges are loaded with H110, A1680, or similar proper powder to cycle AR-15 actions.

Note: These rounds have been tested and cycle properly with our AR-15 300 BLK rifles and pistols. These firearms have adjustable gas blocks and enlarged gas ports and suppressors. You may need similar modifications for your firearm. While most firearms will not need such modification, please be aware of this issue and that if you wish to return this ammo due to cycling problems, you must pay return shipping.

Velocity/ Pressure: To SAAMI pressure and subsonic 1080 FPS from a 16″ barrel.

These are professionally loaded by a bonded/ insured type 7 FFL.

Comes packaged in:

  • 500 Rounds within a heavy duty shipper box
