Nosler 270 Cal 160gr Partition (50ct)

The Nosler 270 Cal 160gr Partition (50ct) is a premium bullet component tailored for handloaders who demand deep penetration, straight-line expansion, and consistent accuracy in .270‑caliber rifles. Utilizing Nosler’s time-tested Partition design—with a hollow-point front core and a heavier steel-core rear section separated by a jacket partition—this 160‑grain projectile delivers uniform frontal expansion and powerful weight retention. Boxes of fifty arrive polished, inspected, and ready for precise seating.

Designed at .277″ diameter with a Spitzer boat‑tail profile, the 270 Cal 160gr Partition optimizes aerodynamic flight stability and reduces trajectory drop. Its dual‑core configuration ensures rapid, controlled expansion in soft tissue, followed by the rear core penetrating deeply—including through bone—to reach vitals. Ideal for cartridges such as .270 Winchester, .270 WSM, and .270 Weatherby Magnum, it suits both woodland and open-country hunting.

Key technical specifications include a ballistic coefficient (G1) of approximately 0.375 and sectional density (SD) around 0.277. The overall bullet length is approximately 1.320″, and stabilization is achieved in rifles with a 1:10″ twist rate. The copper‑alloy jacket and partition support about 60–70% weight retention post-impact, contributing to reliable terminal performance and clean wound channels.

In field use, the 270 Cal 160gr Partition demonstrates ethical terminal behavior: the front core expands uniformly, forming a wide wound channel, while the heavier rear core drives straight through, ensuring deep penetration. Hunters consistently report successful results on deer, elk, and antelope-class game, even at extended ranges. Gentledowns on shoulder bones or heavy bone penetration are no issue for this bullet.

This product is strictly a bullet component—not factory-loaded ammunition—for experienced handloaders. Reloaders should consult Nosler’s official load data and reputable manuals. Recommended powders include Hodgdon H‑4831SC, IMR 4350, or Reloder 19 for balanced velocity, pressure control, and accuracy with the 160‑grain Partition in .270 calibers. Properized seating depth, neck tension, case prep, and consistent overall length are essential for precision handloads.

Combining Nosler’s time-honored Partition core design, aerodynamic boat-tail profile, and meticulous manufacturing, the 270 Cal 160gr Partition bullet component provides consistent accuracy, deep penetration, and ethical terminal performance. It’s an ideal choice for serious hunters and precision shooters working their .270‑caliber handloads.
