Barnes has engineered this .300 Blackout load specifically for shooters running suppressed rifles. The Suppressor Series represents a thoughtful approach to subsonic ammunition—purpose-built rather than compromised.

Key Features

• 205-grain Sierra GameKing projectile designed to expand reliably even at subsonic velocities
• Subsonic velocity (1060 fps) optimized for sound suppression without sacrificing terminal performance
• Clean-burning propellants reduce gas blowback and fouling in your suppressor

Performance Characteristics

The Sierra GameKing bullet is a proven performer in the hunting field. At subsonic velocities, expansion is assured while maintaining the penetration needed for ethical, effective terminal performance. The clean-burning powder selection means less carbon buildup in your suppressor and firearm—a practical consideration for serious suppressed rifle shooters.

This ammunition represents the intersection of sound suppression and hunting effectiveness. Whether you're pursuing game or simply enjoying quieter shooting, Barnes has delivered a load that doesn't ask you to compromise on either front.
