The Hornady 80787 Subsonic ammunition delivers reliable expansion and terminal performance at velocities below the sound barrier. This 7.62x39mm cartridge features a 255-grain Sub-X bullet engineered specifically for suppressed firearms and quiet hunting applications. The heavy projectile maintains lethal energy while producing significantly reduced noise signatures compared to standard velocity loads.
What Makes This Different
The Sub-X bullet design incorporates a lead core with a gilding metal jacket and polymer tip optimized for expansion at subsonic velocities. While conventional bullets often fail to expand reliably below 1,050 fps, the Sub-X consistently opens at velocities as low as 900 fps. The 255-grain weight provides superior sectional density compared to standard 123-grain 7.62x39mm loads, delivering deeper penetration and more consistent terminal ballistics.
Key Features
- 255-grain Sub-X bullet with controlled expansion at subsonic velocities
- Muzzle velocity of approximately 1,050 fps from 16-inch barrel
- Lead core construction with gilding metal jacket for reliable feeding
- Polymer tip initiates expansion while maintaining ballistic coefficient
- Brass cases suitable for reloading applications
- Compatible with standard 7.62x39mm chamber specifications
- Optimized powder charge for consistent cycling in semi-automatic rifles
Field testing demonstrates reliable function in AK-pattern rifles, SKS carbines, and bolt-action platforms chambered in 7.62x39mm. The subsonic velocity eliminates the supersonic crack while maintaining sufficient energy for medium game hunting within 100 yards. The heavy bullet buckets wind better than lighter projectiles, providing more predictable trajectories in variable conditions.
