Nosler 30 Cal 180gr Partition (50ct)

Nosler 30 Cal 180gr Partition (50ct)

The Nosler 30 Cal 180gr Partition (50ct) is a top-tier bullet component designed for handloaders seeking deep penetration, reliable expansion, and consistent accuracy in .30-caliber rifles. Featuring Nosler’s legacy Partition design—a dual-core construction with a jacket partition—this 180-grain projectile delivers uniform expansion up front while the rear core maintains intact mass for deep penetration. Each box contains fifty polished, inspected bullets ready for precise seating.

Crafted with a .308″ bullet diameter and Spitzer boat-tail profile, the 30 Cal 180gr Partition balances aerodynamic efficiency with terminal toughness. The soft front core initiates expansion on impact, while the harder rear core continues into deep tissue and heavy bone—ideal for big-game cartridges like .30‑06 Springfield, .308 Winchester, .300 Winchester Magnum, and .300 WSM. Its design excels in both open-country shots and dense woodland conditions.

Key technical specifications include a ballistic coefficient (G1) of approximately 0.440 (estimated), and a sectional density (SD) near 0.257. Measuring around 1.375″ in overall length, this bullet stabilizes reliably in rifles with 1:10″ twist rates or faster. The jacket-partition ensures approximately 60–70% weight retention, promoting clean penetration and dependable wound channels.

In real-world field use, the 30 Cal 180gr Partition delivers controlled expansion followed by straight-line penetration, producing ethical terminal outcomes on elk, moose, deer, and antelope. Hunters report consistent performance in tough shot scenarios, commending its ability to maintain trajectory and terminal performance at extended ranges.

This is strictly a bullet component—not factory-loaded ammunition—for experienced handloaders. Reloaders should reference Nosler’s official load data and trusted manuals. Recommended powders include Hodgdon H‑4831SC, IMR 4064, or Reloder 15, balancing velocity, pressure control, and consistency with 180‑gr .30-caliber bullets. Proper case prep, neck tension, seating depth, and consistent overall length are essential for maximizing performance and safety.

With Nosler’s classic Partition dual-core strength, aerodynamic design, and high manufacturing precision, the 30 Cal 180gr Partition bullet component stands as an outstanding option for hunters and precision shooters demanding ethical terminal performance, deep penetration, and reliable accuracy in .30‑caliber handloads.
