This ammunition is designed for competitive target shooting, long-range training, and tactical applications where minimizing sound signature and maximizing downrange accuracy are paramount. The cornerstone of this load is the legendary 175-grain Sierra MatchKing Jacketed Hollow Point bullet, a proven design trusted by champions and professionals worldwide.

Key Features

• 175-Grain Sierra MatchKing JHP Bullet: Features the industry-standard MatchKing hollow point boat tail (HPBT) design. This bullet is renowned for its exceptional ballistic coefficient and consistent in-flight performance, providing superior accuracy and wind-bucking capability.
• Subsonic Velocity Profile: Specifically loaded to maintain velocities below the speed of sound (approximately 1,125 fps and below). This eliminates the disruptive sonic crack, significantly reducing report and making it ideal for suppressed shooting or noise-sensitive environments.
• Proprietary Match-Grade Loading: Developed through extensive testing at independent laboratories, this load represents Atomic Ammunition’s commitment to a precise powder charge and consistent seating depth, ensuring minimal velocity deviation and extreme spread for tight groups.
• Enhanced Safety & Reliability: Built on the four foundational principles of reliability, performance, safety, and affordability. Every component and loading process is validated to ensure safe, dependable function in bolt-action and semi-automatic rifles tuned for subsonic ammunition.
• Bulk Value Packaging: Supplied in a convenient box of 100 rounds, allowing serious shooters to maintain a consistent ammunition supply for extended practice sessions or competition without frequent reordering.

Performance & Applications

This ammunition excels in specific, demanding roles where standard supersonic loads are not optimal. Its performance is best realized in a rifle with a barrel twist rate appropriate for stabilizing heavy 175-grain projectiles (typically 1:10″ or faster) and when paired with a sound suppressor.

Suppressed Long-Range Training: The subsonic nature of this round allows for realistic, scaled long-range practice at shorter distances. Shooters can learn wind reading, trigger control, and follow-through without the concussion and noise of full-power rounds, often on ranges with sound restrictions. The predictable trajectory of the MatchKing bullet provides excellent training value.

Precision Rifle Competition (Specialty Stages): Certain matches feature stages where sound reduction is a scoring factor or a tactical advantage. This load provides the mechanical accuracy needed to engage small targets at known distances quietly, giving competitors an edge in these unique scenarios.

Tactical & Recreational Suppressed Use: For law enforcement, military training units, or recreational shooters operating suppressed 308 platforms, this ammunition offers a hearing-safe, low-recoil option for maintaining proficiency, conducting discreet training, or hunting in jurisdictions where subsonic rounds are required for certain game.
