Nosler 375 Cal 300gr Partition (50ct)

The Nosler 375 Cal 300gr Partition (50ct) is a premium bullet component crafted for handloaders seeking deep penetration, controlled expansion, and stopping power in .375-caliber rifle platforms. Featuring Nosler’s renowned Partition dual-core design—with a soft lead front core engineered for reliable expansion and a hard rear core designed for maximum weight retention—this 300 gr projectile delivers consistent wound channels and ethical terminal performance. Each box contains fifty polished, weight-sorted bullets ready for precision seating.

Formed to a .375″ bullet diameter and fitted with a Spitzer boat-tail profile, the 375 Cal 300gr Partition offers enhanced downrange stabilization, flat trajectory, and resistance to wind drift. Upon impact, the front core reliably mushrooms to create effective wound cavities, while the solid rear core penetrates dense tissue and bone—ideal for cartridges such as .375 H&H Magnum, 375 Ruger, 375 Weatherby Magnum, and similar big-bore rifles.

Key technical specifications include a G1 ballistic coefficient (BC) of approximately 0.425 and a sectional density (SD) near 0.326. With an overall length near 1.675″, this bullet stabilizes efficiently in barrels with 1:12″ twist rates or faster. The dual-core jacket configuration supports 60–70% weight retention post-impact, enabling deep, straight-line penetration and reliable terminal performance in large-game situations.

In field testing and real-world use, the 375 Cal 300gr Partition consistently produces clean expansion followed by deep penetration. Hunters report one-shot effectiveness on species such as moose, elk, bear, and African plains game. The aerodynamic boat-tail enhances downrange accuracy, while the robust jacket-core design supports precision and terminal consistency across varied terrain.

This product is strictly a bullet component—not factory-loaded ammunition. Handloaders should reference Nosler’s official load data and reputable reloading manuals. Recommended powders include Hodgdon H‑4831SC, IMR 7828, or Reloder 22—selected for predictable burn rates and safe pressure profiles with heavy .375-caliber bullets. Precise case preparation, consistent neck tension, seating depth, and cartridge overall length are essential for achieving safe, repeatable performance.

Combining Nosler’s dual-core Partition engineering, aerodynamic boat-tail profile, and precision manufacturing, the 375 Cal 300gr Partition bullet component provides handloaders with a top-tier solution for retained energy, deep penetration, and accuracy in heavy-caliber hunting applications.
