The Discreet Ballistics 300 AAC Blackout 188gr Selous Subsonic Hunting/Self Defense load was conceived and designed as part of a two load system. This load has been thoroughly tested for functionality with different length gas systems with a suppressor attached. The load incorporates a machined copper 30 Cal projectile (the Selous bullet) which expands at subsonic velocities above 750 feet per second. This projectile was designed using state-of-the-art ballistics modeling software to maximize stability at subsonic velocities. Discreet Ballistics gives its customers the option of choosing these loads for use in 16″ barrels or 7-11” barrels.
The Two Load System
The Discreet Ballistics’ two load system was conceived so that the shooter of subsonic ammunition can practice with a less costly Target load, and hunt or defend with a premium Hunting/Self-defense load. Methodical load development by Discreet Ballistics has created a system which will minimize point of impact shift allowing the shooter greater confidence when it’s time to hunt or defend.
Note: Feeding issues may occur due to improperly beveled chamber mouths in certain barrels. Additionally feed ramps may need to be polished for optimized feeding of the Selous bullet.
Examples of barrels with correct chamber mouth bevel are AR-Stoner and Rainier Arms.
