Hornady Sub-X 30 Cal .308 175gr 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 and Performance

These 175-grain .308 caliber bullets are engineered to expand reliably at velocities below the speed of sound—a challenge that conventional bullet designs simply cannot meet. The key to their success lies in several integrated features:

• Patented Flex Tip Insert: Located within the hollow point cavity, this innovation promotes consistent expansion even at subsonic velocities where traditional hollow points often fail to open properly.
• Gilding Metal Jacket with Long Grooves: The jacket design reduces bearing surface friction and aids in controlled expansion.
• Flat Profile: Contributes to the bullet's stability and predictable performance at lower velocities.
• Lead Core: Provides the mass and density necessary for deep penetration.

Practical Features

Cannelures are incorporated into the design for positive case crimp, making these bullets well-suited for semiautomatic firearms where consistent feeding and chambering are essential. The 100-count box provides sufficient quantity for serious practice or hunting applications.

Ideal Applications

Sub-X bullets excel in suppressed rifle systems, hunting scenarios where noise reduction is valued, and any application where subsonic performance is desired without compromising terminal effectiveness.
