Sierra 270 Cal 6.8mm 135gr HPBT MatchKing

The Sierra 270 Cal 6.8mm 135gr HPBT MatchKing is a precision component bullet crafted for handloaders and competitive shooters seeking long-range performance, aerodynamic efficiency, and consistent terminal behavior in .270 Winchester, 6.8 SPC, and 6.8 Creedmoor platforms. Featuring a hollow-point Spitzer boat-tail profile with a .270-inch diameter and 135-grain weight, this bullet delivers match-grade accuracy and flight stability.

Built with a sharp Spitzer ogive, hollow-point cavity, and tapered boat-tail base, the 135gr HPBT MatchKing achieves a high G1 ballistic coefficient—typically around 0.510—which minimizes drag, enhances wind resistance, and preserves supersonic velocities at extended ranges. This design ensures flat trajectories and repeatable downrange performance.

Manufactured to Sierra’s strict component tolerances—135.0 grains weight, 0.270″ diameter, approximately 1.065″ overall length, and a sectional density near 0.250—the bullet features uniform jacket thickness, concentric hollow-point geometry, and precise boat-tail alignment. These attributes support consistent ammunition performance, tight group accuracy, and stable seating in precision load development.

Optimized for barrels with 1:9 to 1:10 twist rates, the Sierra 270 Cal 6.8mm 135gr HPBT MatchKing performs best at muzzle velocities between 2,800 and 3,000 fps. Handloaders report sub‑½‑MOA accuracy, excellent wind drift control, and reliable terminal expansion—making this bullet ideal for long-range hunting, PRS, and competition shooting.

As a component bullet, the Sierra 270 Cal 6.8mm 135gr HPBT MatchKing gives reloaders full control over powder selection, primer choice, and seating depth—enabling tailored load crafting for recoil management, trajectory optimization, and terminal performance. It is not factory-loaded ammunition but a high-precision Spitzer MatchKing component designed for custom long-range .270-caliber applications.
