Atomic Ammunition 7.62x39mm 220gr Subsonic HPBT - 50 Round Box

The Atomic Ammunition 00474 delivers precision subsonic performance in 7.62x39mm caliber with 220-grain hollow point boat tail projectiles. This specialized ammunition maintains velocities below the sound barrier while maximizing terminal effectiveness through advanced bullet design. Shooters gain the tactical advantage of reduced noise signature without sacrificing stopping power or accuracy.

What Makes This Different

Unlike standard velocity 7.62x39mm rounds that create sonic cracks, this subsonic load operates at approximately 1,050 fps to remain below the sound barrier. The 220-grain weight provides superior sectional density compared to typical 123-grain loads, delivering deeper penetration and enhanced terminal ballistics. The hollow point boat tail design combines expansion characteristics with improved ballistic coefficient for better downrange performance.

Key Features

• 220-grain hollow point boat tail bullets for maximum terminal effectiveness
• Subsonic velocity eliminates sonic crack for reduced noise signature
• Premium brass cases with consistent powder charges for reliable cycling
• Compatible with standard 7.62x39mm chambers including AK-pattern rifles
• 50-round factory packaging with consistent quality control
• Boat tail design improves ballistic coefficient and long-range stability
• Heavy bullet weight provides superior penetration characteristics

This ammunition excels in applications requiring noise reduction while maintaining lethal effectiveness. The subsonic velocity makes it ideal for suppressed firearms, reducing overall sound signature significantly. Hunters appreciate the reduced noise for follow-up shots, while tactical applications benefit from decreased muzzle blast and flash. The heavy 220-grain projectile maintains energy effectively at extended ranges despite lower velocity.
