Nosler 338 Cal 250gr Partition (50ct)

The Nosler 338 Cal 250gr Partition (50ct) is a premium bullet component crafted for handloaders seeking deep penetration, controlled expansion, and heavy-game performance in .338-caliber rifles. This 250gr projectile features Nosler’s legendary Partition dual-core design—with a soft front core for reliable expansion and a hard rear core for maximum mass retention—ensuring uniform wound channels and consistent terminal results. Each box includes fifty polished and inspected bullets ready for precise handloading.

Engineered with a .338″ bullet diameter and a Spitzer boat-tail profile, the 338 Cal 250gr Partition achieves excellent aerodynamic efficiency and stability downrange. The front core initiates controlled expansion creating broad wound cavities, while the rear core drives through dense tissue and bone—ideal for cartridges such as .338 Winchester Magnum, 338 Edge, 338 Lapua, and 34 Nosler.

Key specifications include a ballistic coefficient (G1) of approximately 0.530 and a sectional density (SD) near 0.285. With an overall bullet length of about 1.500″, this bullet is stabilized in 1:10″ twist rate barrels or faster. The Partition jacket and internal core partition support roughly 60–70% weight retention post-impact, promoting deep, straight-line penetration and ethical performance on elk, moose, bear, and similar large game.

In field testing, the 338 Cal 250gr Partition delivers consistent expansion followed by strong retained mass—resulting in reliable one-shot performance on heavy-boned game. The boat-tail design maintains flight stability across long distances and through adverse wind conditions. Hunters report clean wound channels, deep penetration, and terminal reliability even at extended ranges.

This is strictly a bullet component—not factory-loaded ammunition. Handloaders should reference Nosler’s official load data and trusted reloading manuals. Recommended powders include Hodgdon H‑4831SC, IMR 7828, or Reloder 22 for safe, accurate performance with this 250gr projectile. Proper case preparation, neck tension, seating depth, and consistent cartridge overall length are essential to unlock premium accuracy and maintain safe pressure levels.

By combining Nosler’s dual-core Partition innovation, SP boat-tail aerodynamics, and precision manufacturing, the 338 Cal 250gr Partition bullet component is an elite choice for serious hunters and precision shooters demanding deep penetration, retained energy, and downrange accuracy in .338-caliber handloads.
