Description
You didn't build a 300 Blackout to shoot supersonic ammunition—you built it to run a suppressor with subsonic loads that sound like Hollywood thinks guns sound.
At 220 grains, this is proper subsonic 300 Blackout. Velocities stay well below the speed of sound (typically 950-1050 fps), which means no supersonic crack. Just the mechanical action of your firearm and the whoosh of expanding gases through your suppressor. This is what the 300 Blackout cartridge was designed for.
The heavy 220 grain FMJ bullet provides the mass needed to cycle AR-platform firearms reliably at subsonic velocities. Lighter bullets at lower speeds won't cycle the action; 220 grains has enough momentum to run the system properly. It's the proven subsonic bullet weight that has become the standard for suppressed 300 Blackout applications.
AngelFire remanufactures this ammunition using once-fired brass and carefully measured powder charges calibrated specifically for subsonic performance. Each round is inspected to ensure proper assembly—critical for suppressor-safe pressures and reliable function.
This 100-round case provides enough ammunition for zero verification, suppressor break-in, and real-world application. For 300 Blackout owners who actually use their suppressor, this is affordable subsonic ammunition that works.
