Sellier & Bellot 300 Blackout 147gr FMJ Subsonic – 20 Rounds

Sellier & Bellot's 300 Blackout subsonic load delivers reliable feeding and function in suppressed or unsuppressed platforms. The 147-grain full metal jacket bullet is optimized for subsonic velocity, minimizing noise signature while maintaining clean cycling in AR-15 pattern rifles and similar platforms chambered in 300 BLK. This European-manufactured ammunition is known for consistent velocities and clean-burning powder, making it a solid choice for range work and suppressor use.

Compatible with any firearm chambered in 300 AAC Blackout, this load uses boxer-primed brass cases suitable for reloading. Available in 20-round boxes or 1,000-round cases for shooters who prioritize volume and value. Factory-fresh components ensure reliable ignition and feeding across a wide range of barrel lengths.
