Winchester USA 300 Blackout 147gr FMJ – 20 Rounds

Winchester USA 300 Blackout 147-grain FMJ delivers reliable subsonic performance for bolt-action and semi-automatic rifles chambered in 300 BLK. The heavy 147-grain full metal jacket bullet stays subsonic from standard 16" barrels, making it well-suited for suppressed shooting while maintaining consistent accuracy and function. This load uses clean-burning powder and non-corrosive Boxer primers for dependable cycling in AR-15 platform rifles and other 300 Blackout firearms.

Packaged in 20-round boxes with 200 rounds per case. Brass cases are reloadable. This subsonic load operates at reduced chamber pressures compared to supersonic 300 Blackout ammunition — it won't cycle the action in all gas systems without a suppressor or adjustable gas block.
