Atomic 00465 300 Blackout 220gr HPBT Subsonic Ammo 50rd Box

The Atomic Ammunition 00465 delivers precision subsonic performance in 300 Blackout, engineered for suppressed shooting applications where noise reduction and terminal effectiveness matter most. This 220-grain hollow point boat tail load maintains consistent velocities below the sound barrier while delivering reliable expansion on target.

What Makes This Different

Unlike standard supersonic loads that create sonic cracks, this subsonic ammunition stays below 1,050 fps to eliminate the sound barrier break. The 220-grain hollow point boat tail design provides superior ballistic coefficient compared to flat-base bullets, maintaining energy downrange while ensuring reliable feeding in semi-automatic platforms. Each cartridge undergoes quality control testing to ensure consistent powder charges and proper case preparation.

Key Features

• 220-grain hollow point boat tail bullet for controlled expansion
• Subsonic velocity eliminates sonic crack when suppressed
• Boxer-primed brass cases suitable for reloading
• Compatible with standard 300 Blackout chambers and magazines
• Consistent powder charges for reliable cycling in gas systems
• 50 rounds per box, 10 boxes per case (500 total rounds)
• Factory-fresh ammunition with quality control testing

This ammunition excels in tactical applications where sound signature reduction is critical, hunting scenarios requiring clean terminal performance, and precision shooting where consistent velocities matter. The heavy bullet weight provides excellent penetration through barriers while the hollow point design ensures reliable expansion in soft targets. The subsonic velocity profile works effectively with adjustable gas blocks and suppressor-optimized barrel lengths.
