Hornady Sub-X .458 410gr Subsonic Rifle Bullets

Hornady Sub-X Subsonic Expanding Bullets

The Sub-X represents a thoughtful solution to a specific problem: delivering effective rifle performance without excessive noise. These bullets are engineered to function reliably at subsonic velocities—below the speed of sound—making them ideal for suppressed rifles and hunting applications where noise reduction matters.

Design and Construction

Core Features:

• Lead core construction for consistent weight and performance
• Gilding metal jacket with long grooves for controlled expansion
• Patented Flex Tip insert positioned in the hollow point cavity
• Flat profile optimized for subsonic performance
• Cannelure groove for positive case crimp

Performance Characteristics

The Flex Tip technology is the key to Sub-X performance. At velocities where conventional hollow points may not expand reliably, the Flex Tip insert initiates and controls expansion, ensuring the bullet opens up predictably while maintaining deep penetration. This combination of expansion and penetration makes Sub-X effective on medium game at subsonic velocities.

Practical Applications

The cannelure groove provides a secure crimp point, making these bullets particularly well-suited for semiautomatic rifles where consistent feeding and reliable crimping are essential. Whether you're handloading for a suppressed hunting rifle or developing subsonic loads for target shooting, Sub-X bullets offer the reliability and performance you need.
