The Winchester USA 300 Blackout 147gr Full Metal Jacket Open Tip delivers reliable subsonic performance for suppressed shooting and tactical applications. This precision-manufactured ammunition provides consistent velocities and clean burning propellant for reduced fouling in gas-operated firearms.
What Makes This Different
The 147-grain bullet weight sits in the optimal subsonic range for 300 Blackout, cycling reliably through both bolt-action and semi-automatic platforms without the sharp crack of supersonic rounds. Winchester's open tip design enhances accuracy by creating a more uniform bullet profile compared to standard FMJ rounds. The heavier projectile maintains energy downrange while producing significantly less noise signature when fired through suppressors.Key Features
