Nosler 284 Cal 7mm 150gr Partition (50ct)

The Nosler 284 Cal 7mm 150gr Partition® bullet represents the pinnacle of controlled expansion and penetration for 7mm handloaders pursuing medium to large game. Utilizing Nosler’s iconic dual-core Partition® design, this bullet delivers rapid front-core expansion while preserving the integrity of its rear core to achieve deep, straight-line penetration through thick hide, bone, and dense muscle.

At a .284″ diameter and 150-grain weight, the 7mm Partition® features a tapered copper-alloy jacket and an internal partition wall that maintains weight retention exceeding two-thirds of the bullet’s mass. The result is a devastating combination of energy transfer and structural integrity—producing lethal wound channels and reliable terminal performance on big game such as deer, antelope, elk, and moose.

With a G1 ballistic coefficient (BC) of 0.456 and a sectional density (SD) of 0.266, this bullet maintains flat trajectories, high downrange velocity, and excellent wind resistance. Its boat-tail base and spitzer profile deliver superb aerodynamic stability and consistent seating depth across a wide variety of 7mm cartridges including .284 Winchester, 7mm-08 Remington, and 7mm Remington Magnum.

Measuring 1.220″ in overall length (OAL), the 150gr Partition® is optimized for 1-in-8″ to 1-in-9″ twist barrels, ensuring stable flight even at extended ranges. Typical handloads producing muzzle velocities between 2,700 and 2,900 fps deliver massive tissue disruption and deep, ethical penetration at all practical hunting distances.

Each bullet is manufactured and inspected in the USA to Nosler’s rigorous standards for jacket concentricity, core bonding, and dimensional accuracy. The result is tight groupings, uniform muzzle velocities, and repeatable field results—qualities that define the Nosler Partition’s legendary reputation among experienced hunters and handloaders.

Designed for those who require reliability, precision, and terminal confidence, the Nosler 284 Cal 7mm 150gr Partition® remains a trusted choice for big-game pursuits across North America, from open plains to rugged timber.
