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 with a premium load utilizing the Selous Machined Expander. 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.
Note: The Selous projectile feeds best with 300BLK specific magazines like those from Magpul, Lancer and D&H
