Sierra 243 Cal 6mm 107gr HPBT MatchKing

The Sierra 243 Cal 6mm 107gr HPBT MatchKing is a premium component bullet designed for precision handloading and competitive shooting in mid-range and varmint platforms. As part of Sierra’s elite MatchKing series, this .243‑inch, 107‑grain hollow-point boat-tail bullet delivers match-grade accuracy, exceptional aerodynamic performance, and consistent downrange results.

Featuring a hollow-point meplat and tapered boat-tail base, the 243 Cal 6mm 107gr HPBT achieves a G1 ballistic coefficient of approximately 0.490. This high BC minimizes drag and wind drift, resulting in flat trajectories and enhanced velocity retention at extended ranges. The .243″ diameter ensures compatibility with cartridges such as .243 Winchester, 6mm Creedmoor, and 6mm-06, making it a top choice for precision shooters.

Constructed to rigorous factory tolerances—107.0 grains weight, .243″ diameter, approximately 1.055″ overall length, and a sectional density around 0.227—the Sierra 243 Cal 6mm 107gr HPBT MatchKing offers uniform jacket thickness, concentric meplat alignment, and precise base geometry. The hollow-point cavity supports consistent meplat formation, while the boat-tail reduces drag and stabilizes flight at supersonic velocities.

Optimized for bolt-action and precision semi-auto rifles with twist rates of 1:8 to 1:9, this bullet component consistently achieves sub‑½‑MOA accuracy in match and varmint load applications. Handloaders report tight groupings and dependable performance when tuned with quality brass and match primers.

As a component bullet, the Sierra 243 Cal 6mm 107gr HPBT MatchKing gives reloaders full control over powder selection, primer type, and seating depth—enabling precise load development for recoil, trajectory, and terminal performance. It is not factory-loaded ammunition but is engineered for shooters pursuing precision and customization at the component level.

In summary, the Sierra 243 Cal 6mm 107gr HPBT MatchKing is a high-performance hollow-point boat-tail bullet that blends aerodynamic efficiency, match-grade accuracy, and reloader flexibility. Ideal for precision target work, varmint control, and competitive shooting, this 107gr MatchKing delivers consistent, top-tier performance for selective shooters.
