Nosler 375 Cal 260gr Partition (50ct)

Nosler 375 Cal 260gr Partition (50ct)

The Nosler 375 Cal 260gr Partition (50ct) is a premium bullet component designed for handloaders seeking deep penetration, controlled expansion, and reliable terminal performance in .375‑caliber rifles. Featuring Nosler’s famed Partition dual-core design—with a softer lead front core for dependable expansion and a harder rear core for maximum weight retention—this 260gr projectile delivers consistent wound channels and ethical terminal effects on large game. Each box contains fifty polished, weight-sorted bullets ready for precise seating.

Machined to a .375″ bullet diameter and featuring a Spitzer boat-tail profile, the 375 Cal 260gr Partition offers excellent downrange stability, flat trajectory, and wind resistance. The front core initiates uniform expansion upon impact, while the hard rear core drives through thick hide and dense bone—making it well-suited for cartridges such as .375 H&H Magnum, 375 Weatherby, and other .375-caliber magnum platforms.

Key specifications include a ballistic coefficient (G1) of approximately 0.310 and a sectional density (SD) near 0.296. With an overall length around 1.650″, this bullet stabilizes effectively in barrels with 1:12″ twist rates or faster. The Partition jacket and internal core design retain approximately 60–70% of the bullet’s weight post-impact, promoting deep, straight-line penetration and ethical terminal performance on large and dangerous game.

In field applications, the 375 Cal 260gr Partition produces controlled expansion followed by straight-line penetration. Hunters report clean one-shot kills on moose, elk, cape buffalo, and other heavy game—even at moderate ranges. Its boat-tail design improves aerodynamic efficiency and downrange accuracy, allowing for precise shot placement across varied hunting environments.

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 to safely propel this heavy .375-caliber projectile. Proper case preparation, uniform neck tension, correct seating depth, and consistent cartridge overall length are essential for achieving safe pressures and repeatable accuracy.

Combining Nosler’s proven dual-core Partition engineering, streamlined boat-tail aerodynamics, and precision craftsmanship, the 375 Cal 260gr Partition bullet component offers handloaders a top-tier solution for terminal reliability, deep penetration, and long-range accuracy in .375‑caliber rifle platforms.
