Hornady Subsonic 300 Blackout 190gr Sub-X
Purpose-Built for Subsonic Performance
Hornady Subsonic ammunition represents a thoughtful approach to modern rifle shooting. Designed specifically for performance below the speed of sound, this load pairs reduced noise with genuine stopping power—a combination that appeals to both the serious shooter and the newcomer alike.
Advanced Sub-X Bullet Technology
The 190-grain Sub-X bullet is engineered with several distinctive features:
- Flex Tip Insert: A patented hollow-point design that initiates reliable expansion at low velocities
- Gilding Metal Jacket: Features long grooves that work in concert with the bullet's flat profile to ensure consistent expansion
- Lead Core with Cannelure: Provides weight retention and secure case crimping for semi-automatic rifles
- Ballistic Coefficient: 0.437 for predictable flight characteristics
Real-World Performance
This ammunition meets or exceeds FBI Protocol terminal ballistic standards. Testing demonstrates 16-18 inches of penetration with 90% or greater weight retention—the hallmark of a bullet that performs as intended.
Practical Advantages
Reduced Noise and Recoil: The subsonic velocity of 1050 fps produces a significantly quieter report than supersonic loads. When paired with a suppressor, the result is genuinely quiet shooting.
Optimized Powders: Hornady's subsonic powder selection delivers low flash signature, making this ammunition suitable for both suppressed and unsuppressed use.
Training and Enjoyment: Lower recoil and noise make this an excellent choice for new shooters, extended practice sessions, and anyone seeking a more pleasant shooting experience.
