Hornady Sub-X 350 Legend 250 Grain Subsonic Bullets

Hornady Sub-X Subsonic Expanding Bullets

The Sub-X represents a thoughtful solution to a specific problem: delivering effective terminal performance from subsonic ammunition without sacrificing reliability or accuracy.

Design Philosophy

These bullets are engineered to function at velocities below the speed of sound—typically 1,125 feet per second or less. This approach offers distinct advantages for shooters seeking reduced noise signatures while maintaining downrange effectiveness.

Key Features

• Patented Flex Tip Insert: Located within the hollow point cavity, this innovation ensures consistent expansion even at the reduced velocities inherent to subsonic loads
• Gilding Metal Jacket: Long grooves along the jacket work in concert with the bullet's flat profile to promote reliable expansion
• Lead Core: Provides weight and penetration characteristics suitable for medium game and defensive applications
• Cannelure: A crimping groove that locks the bullet securely in the case, making these rounds ideal for semi-automatic firearms where case integrity is essential

Practical Applications

Sub-X bullets excel in scenarios where noise reduction matters—whether for hearing protection, hunting in noise-sensitive areas, or training applications. The 250-grain weight in 35 caliber delivers substantial energy transfer while remaining subsonic in most rifle platforms.
