Sierra .308 195gr Tipped MatchKing 100pk S7795: An Overview
The Sierra .308 195gr Tipped MatchKing (TMK) S7795 is a high-performance bullet designed for precision shooting and long-range applications. With its advanced design and impressive specifications, it has quickly become a favorite among competitive shooters and enthusiasts alike.
Key Features
High Ballistic Coefficient
One of the standout features of the Sierra 195gr TMK is its exceptional G1 ballistic coefficient (BC) of 0.610 when fired at velocities above 2,000 feet per second. This high BC allows for reduced drag, resulting in flatter trajectories and less wind drift compared to other bullets in its class. For instance, the widely used 175gr Sierra MatchKing (SMK) has a BC of only 0.496, making the TMK a superior choice for long-range shooting.
Optimal Twist Rate
Sierra recommends using the 195 TMK with barrel twist rates of 1:10″ or faster. This specification ensures that the bullet stabilizes properly during flight, which is crucial for maintaining accuracy at extended distances.
Versatile Load Development
The Sierra 195 TMK is compatible with various powders, including IMR 4064 and Varget, both popular choices among reloaders. Initial load development tests have shown promising results with velocities ranging from approximately 2,394 to 2,536 feet per second, depending on the powder charge. The average group sizes achieved during testing were around 0.692 inches, demonstrating excellent accuracy potential.
Performance Insights
Accuracy and Consistency
In practical tests conducted with custom rifles chambered in .308 Winchester, the Sierra 195 TMK has consistently delivered tight groupings. For example, one test reported five-shot groups as small as 0.498 MOA, showcasing its capability for precision shooting. The average standard deviation across various loads was about 12.5 feet per second, indicating reliable performance.
Long-Range Capabilities
When comparing the performance of the 195 TMK against other common match bullets at distances up to 1,000 yards, it exhibits significantly less drop and drift than both the 175 SMK and other competitors. This makes it an ideal choice for F-TR competitors and long-range benchrest shooters who require consistent performance under varying conditions.
