The Discreet Ballistics 300 AAC Blackout 188gr Selous Machined Expander is a subsonic hunting and/or self defense load that 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 optimized for either 16″ barrels or 7-11” barrels. NEW: Customers can now choose between Lapua 300BLK brass or Jagemann 300BLK brass (Apex headstamp)
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: The Selous projectile feeds best with 300BLK specific feed ramps. M4-style (narrow) feed ramps may need to be polished/widened for optimized feeding of the Selous bullet – Here is a video on how to do that.
