- Manufactured to exacting tolerances for match-grade consistency shot to shot
- Optimized for .308 Winchester / 7.62x51mm chambered rifles and platforms
- Ideal for suppressed rifle builds where sound signature must be minimized
- Conveniently packaged in 20-round boxes for range sessions and field use
Who This Is For
This ammunition is purpose-built for competitive shooters, precision marksmen, and suppressor owners running .308 Winchester platforms who need sub-sonic loads that feed reliably and group consistently. Whether you're running a bolt-action precision rifle or a semi-automatic with a suppressor, CorBon Precision Match Subsonic gives you the quiet, accurate performance required for accuracy-dependent applications where every round counts.

Frequently Asked Questions
Will this subsonic .308 ammo cycle reliably in a semi-automatic rifle?
Subsonic ammunition can sometimes fail to cycle reliably in gas-operated semi-automatic rifles, since the lower chamber pressure may not generate enough gas to fully cycle the action. Many shooters pair subsonic .308 loads with an adjustable gas block set to a more closed position, or use this ammunition in bolt-action rifles where manual cycling eliminates the concern entirely. We recommend testing with your specific platform to confirm reliable function before field use.
Is this ammunition optimized for use with a suppressor?
Yes. CorBon Precision Match Subsonic .308 Win is specifically designed to stay below the speed of sound (~1,125 fps), which eliminates the supersonic crack that standard ammunition produces. When paired with a quality .308-rated suppressor, this load provides a significantly reduced noise signature, making it a popular choice for suppressed precision rifles used in tactical training, pest control, and quiet range sessions.
How does the 185-grain FMJ bullet affect accuracy and trajectory compared to standard .308 loads?
The heavier 185-grain projectile traveling at subsonic velocities will have a more pronounced arc and shorter effective range compared to standard 147–175 grain supersonic .308 loads. However, within its effective range, the match-grade construction and tight manufacturing tolerances of CorBon Precision Match deliver excellent shot-to-shot consistency and tight groupings. This load is best suited for shorter to medium-range precision applications rather than long-range shooting.
