Description

In Stock: Atomic Ammunition Match Subsonic 308 Winchester Ammo 175 Grain Sierra MatchKing Jacketed Hollow Point Box of 100 is factory-loaded match-grade ammunition engineered for suppressed precision rifles where stealth and terminal performance are mission-critical. This load is for the shooter who demands subsonic reliability without sacrificing the ballistic consistency of the legendary Sierra MatchKing bullet. Its primary differentiator is a specialized powder charge designed to remain stable and consistent at subsonic velocities, a factor that separates it from downloaded standard rounds.

Key Features

• 175gr Sierra MatchKing BTHP: The industry-standard projectile for long-range accuracy. Its boat-tail hollow point design maintains a high ballistic coefficient for stable flight, even at reduced velocity.
• Optimized Subsonic Propellant: Uses a powder specifically selected to burn completely within a shorter barrel length, ensuring consistent velocity and reduced muzzle flash. This matters for shot-to-shot repeatability.
• Match-Grade Brass & Primers: Built on quality, reloadable brass with sensitive primers for reliable ignition. This provides a solid foundation for precision, shot after shot.
• Suppressor-Ready Design: Engineered to stay below 1050 feet per second, eliminating the sonic crack. This allows for discreet training or hunting without compromising on bullet performance downrange.
