Atomic 223 Rem 77gr Subsonic HPBT Ammunition - 50rd Box

The Atomic Ammunition 00429 delivers precision subsonic performance in 223 Remington with 77-grain hollow point boat tail construction. This specialized load operates below the sound barrier while maintaining terminal effectiveness for suppressed shooting applications.

What Makes This Different

Subsonic velocity eliminates the sonic crack that standard 223 ammunition produces, creating a significantly quieter shooting experience when paired with suppressors. The 77-grain bullet weight provides superior ballistic coefficient compared to lighter subsonic loads, maintaining downrange energy and accuracy. This ammunition achieves consistent velocities under 1,100 fps while delivering reliable expansion through the hollow point design.

Key Features

• 77-grain hollow point boat tail bullet for enhanced accuracy and terminal performance
• Subsonic velocity eliminates sonic crack for suppressed shooting
• Match-grade construction with consistent powder charges
• Boxer-primed brass cases suitable for reloading
• Boat tail design improves ballistic coefficient and wind resistance
• 50 rounds per box packaging for extended range sessions
• Compatible with standard 223 Rem and 5.56 NATO chambers

This ammunition excels in tactical training scenarios where noise reduction is critical, precision rifle competitions requiring subsonic divisions, and hunting situations demanding quiet follow-up shots. The heavy bullet construction maintains stability through various barrel twist rates while the hollow point ensures reliable expansion on target. Quality control standards ensure consistent performance across temperature ranges and storage conditions.
