Nosler 243 Cal 6mm 85gr Partition (50ct)

The Nosler 243 Cal 6mm 85gr Partition® bullet is engineered for hunters and precision handloaders who demand deep penetration, consistent expansion, and proven field performance. Built on Nosler’s time-tested dual-core Partition® design, the bullet’s forward lead core expands rapidly upon impact for devastating energy transfer, while the rear core remains intact to ensure exceptional weight retention and complete penetration on medium-sized game.

With a G1 Ballistic Coefficient (BC) of 0.315 and Sectional Density (SD) of 0.206, the 85-grain Partition delivers flat trajectories, reliable accuracy, and powerful terminal energy over common hunting ranges. Its spitzer profile and flat-base configuration promote excellent in-flight stability and consistent performance in both bolt-action and semi-automatic rifles.

The bullet measures 0.950″ in overall length, optimizing cartridge fit for .243 Winchester, 6mm Remington, and 6mm Creedmoor applications. While Nosler does not publish a specific minimum twist rate, extensive field testing has shown reliable stabilization in 1-10″ and faster twist barrels, with 1-9″ twists often delivering match-grade accuracy potential.

Each Partition® bullet undergoes Nosler’s strict quality control inspection for jacket concentricity, core bonding, and dimensional precision. The tapered copper-alloy jacket and reinforced base provide structural integrity at magnum velocities, while the front section’s thinner jacket ensures immediate expansion on impact—creating wide wound channels and ensuring humane, one-shot kills.

Ideal for hunting deer, antelope, and hogs, the Nosler 6mm 85gr Partition® excels in field performance where penetration, precision, and ethical lethality are non-negotiable. Whether handloaded for traditional hunting cartridges or modern 6mm platforms, it delivers the dependable terminal results Nosler’s Partition line is famous for.
