Sellier & Bellot 300 Blackout 200gr FMJ Subsonic Ammo 20rd Box

The Sellier & Bellot SB300BLKSUBA delivers reliable subsonic performance for 300 Blackout platforms requiring quiet operation and reduced muzzle signature. This 200-grain full metal jacket ammunition maintains consistent velocities below the sound barrier while providing excellent accuracy and terminal performance. Czech-manufactured precision meets American shooting standards in this premium subsonic load.

What Makes This Different

Unlike standard supersonic 300 Blackout loads, this subsonic configuration operates at velocities under 1,100 fps to eliminate the sonic crack. The heavy 200-grain FMJ bullet provides superior ballistic coefficient compared to lighter projectiles, maintaining energy downrange. Sellier & Bellot's consistent powder charges and quality control deliver shot-to-shot uniformity that competitive shooters and tactical operators demand.

Key Features

• 200-grain full metal jacket bullet for deep penetration and consistent expansion
• Subsonic velocity eliminates sonic boom for suppressed shooting applications
• Boxer-primed brass cases suitable for reloading
• Non-corrosive powder and primers prevent barrel deterioration
• Factory-fresh ammunition with consistent powder charges
• Compatible with all 300 Blackout chambered firearms

This ammunition excels in suppressed rifle applications where noise reduction takes priority over maximum velocity. Law enforcement agencies utilize subsonic loads for urban operations requiring discretion. Hunters appreciate the reduced report when hunting near populated areas, while competitive shooters value the consistent accuracy for precision matches. The heavy bullet weight maintains sufficient energy for effective terminal performance at typical engagement distances.
