Sierra Bullets .303 Cal .311 - 180gr Sp 100ct

Sierra Bullets .303 Cal .311 180gr SP ammunition delivers match-grade reloading components purpose-built for .303 British rifle platforms and similar 7.7mm caliber applications. These 180-grain soft-point projectiles are engineered for hunters and precision shooters who demand reliable expansion and consistent ballistic performance downrange. Whether you're handloading for a Lee-Enfield, Mosin-Nagant, or other .303-chambered rifle, Sierra's proven bullet design provides the accuracy and terminal performance required for medium-game hunting and tactical training scenarios.

The 180-grain spitzer profile balances sectional density (.266 SD) with aerodynamic efficiency, delivering a ballistic coefficient of .411 at 2000 fps—a combination that maintains velocity and energy retention across extended shooting distances. Sierra's soft-point construction initiates controlled expansion on impact while maintaining structural integrity, critical for ethical and effective terminal ballistics. The .311-inch diameter ensures proper fit in .303 British chambers, and the consistent weight distribution across each 100-round box supports repeatable handloading and shot-to-shot accuracy that competitive reloaders and precision shooters expect from Sierra's manufacturing standards.

Tactical and military small-arms enthusiasts, historical rifle collectors, and handloaders restoring British service rifle capabilities will find this 100-count box an economical foundation for consistent ammunition development. The Sierra Bullets .303 Cal .311 180gr SP rounds pair seamlessly with standard .303 British brass, standard large rifle primers, and established powder charges documented in reloading manuals. For shooters validating zero on vintage platforms or developing load data for improved accuracy, this component box supports both training volume and precision verification without the cost premium of factory ammunition.
