Hornady Sub-X 7.62x39 255gr Subsonic Bullets

Hornady Sub-X Subsonic Expanding Bullets

The Hornady Sub-X represents a significant advancement in subsonic ammunition technology. These bullets are purpose-built to deliver reliable expansion and deep penetration at velocities below the speed of sound—typically around 900 fps or lower.

Design Features

Construction and Materials

• Lead core with gilding metal jacket
• Long grooves in the jacket reduce bearing surface and improve velocity consistency
• Flat profile optimizes subsonic ballistics
• Cannelures provide positive case crimp for semiautomatic weapons

Patented Flex Tip Technology

• Innovative insert within the hollowpoint cavity
• Engineered to initiate reliable expansion at subsonic velocities
• Maintains structural integrity through barriers
• Meets FBI protocol for terminal ballistic performance

Performance Characteristics

These 255-grain bullets are specifically designed for the 7.62x39 cartridge and will function reliably in a variety of platforms, including gas system rifles and semiautomatic weapons. The combination of the Flex Tip insert and controlled expansion geometry ensures consistent performance across different firearms and shooting conditions.

Practical Applications

Sub-X bullets excel in suppressed rifle applications where subsonic velocities are preferred. They're equally suitable for hunting and sport shooting where deep penetration and controlled expansion are priorities. The cannelured design ensures secure seating in reloaded ammunition.
