Nosler 9.3mm 286gr Partition (50ct)

The Nosler 9.3mm 286gr Partition (50ct) is a premium bullet component tailored for handloaders seeking controlled expansion, deep penetration, and ethical terminal performance in 9.3 mm (.366″) safari-class rifles. Featuring Nosler’s legendary Partition dual-core design—with a soft lead front core for predictable expansion and a hardened rear core for maximum mass retention—this 286gr projectile delivers consistent wound channels and dependable performance on large and dangerous game. Each box contains fifty polished, weight-sorted bullets ready for precise handloading.

Engineered to a .366″ bullet diameter with a modern Spitzer boat-tail profile, the 9.3mm 286gr Partition achieves excellent aerodynamic efficiency and downrange stability. The front core initiates controlled expansion on impact, producing a balanced energy transfer, while the rear core drives deep into thick hide and heavy bone—ideal for cartridges such as 9.3×62 mm, 9.3 mm Mauser, and big-bore 9.3 mm magnum wildcats.

Key technical specifications include a G1 ballistic coefficient of approximately 0.380 and a sectional density (SD) near 0.296. With an overall bullet length around 1.600″, this bullet stabilizes well in barrels with 1:10″–1:12″ twist rates. The dual-core jacket system supports approximately 60–70% weight retention post-impact, promoting deep, straight penetration and ethical terminal performance on large game.

In field applications, the 9.3mm 286gr Partition consistently yields wide wound channels with deep-point penetration, resulting in clean, one-shot kills on moose, elk, bear, and thick-skinned African plains game like kudu and eland. Hunters report retained energy, straight wound pathways, and effective terminal consistency even at moderate-to-extended ranges.

This product is strictly a bullet component—not factory-loaded ammunition. Handloaders should consult Nosler’s official load data and trusted reloading manuals. Recommended powders include IMR 4831, Hodgdon Retumbo, or Reloder 22—to balance pressure, velocity, and performance with this heavy 9.3 mm projectile. Correct case prep, neck tension, seating depth, and consistent cartridge overall length are essential for achieving safe pressures and premium accuracy.

Combining Nosler’s durable Partition dual-core engineering, boat-tail aerodynamic design, and meticulous manufacturing, the 9.3mm 286gr Partition bullet component is an exceptional choice for serious hunters and precision shooters who demand deep penetration, excellent retained energy, and ethical terminal performance in 9.3 mm rifle platforms.
