Sierra 270 Cal 6.8mm 130gr SBT

The Sierra 270 Cal 6.8mm 130gr SBT is a high-performance component bullet crafted for handloaders and hunters seeking magnum-level accuracy, aerodynamic efficiency, and deep terminal penetration in .270 and 6.8 mm platforms. Featuring a .270‑inch diameter and a 130‑grain Spitzer boat-tail profile, this bullet delivers long-range consistency and enhanced energy retention in rifles such as .270 Winchester, 6.8 SPC, and 6.8 Creedmoor.

Featuring a tapered Spitzer ogive and streamlined boat-tail base, the 130gr SBT achieves a G1 ballistic coefficient of approximately 0.500. This aerodynamic profile significantly reduces drag, enhances stability, and supports flat trajectory at extended ranges. The Spitzer shape also ensures smooth feeding and reliable cycling in bolt-action and semi-auto platforms.

Manufactured to Sierra’s exacting tolerances—130.0 grains weight, 0.270″ diameter, approximately 1.045″ overall length, and a sectional density near 0.242—the bullet maintains consistent jacket thickness, precise meplat alignment, and uniform boat-tail geometry. These tight specifications contribute to repeatable pressure levels, stable flight paths, and sub‑MOA accuracy in precision handloads.

Optimized for bore twist rates between 1:9 and 1:10, the Sierra 270 Cal 6.8mm 130gr SBT performs best at velocities of 2,900–3,100 fps. Handloaders report consistent groupings, excellent wind resistance, and deep terminal penetration—making it ideal for big-game hunting and long-range precision shooting.

As a component bullet, the Sierra 270 Cal 6.8mm 130gr SBT gives reloaders full control over powder selection, primer choice, and seating depth—enabling tailored load development for recoil balance, trajectory optimization, and terminal performance. This is not factory-loaded ammunition, but a premium Spitzer match-grade component designed for serious custom loads.
