Nosler 270 Cal 140gr Partition (50ct)
The Nosler 270 Cal 140gr Partition (50ct) is a premium bullet component crafted for handloaders seeking a balance of reliable expansion, deep penetration, and consistent accuracy in .270-caliber rifles. Featuring Nosler’s time-tested Partition design—with a dual-core structure separated by a jacket partition—this 140‑grain projectile delivers controlled frontal expansion and substantial rear mass retention. Each box includes fifty polished, inspected bullets for precise seating.
Engineered with a .277″ bullet diameter and Spitzer boat-tail profile, the 270 Cal 140gr Partition offers excellent aerodynamic performance, flat trajectories, and wind resistance. The soft front core reliably expands upon impact to create effective wound channels, while the harder rear core ensures deep penetration—ideal for prey ranging from deer to elk-class game. Compatible cartridges include .270 Winchester, .270 WSM, and .270 Weatherby Magnum.
Key technical specifications include a ballistic coefficient (G1) of approximately 0.390 and a sectional density (SD) near 0.248. With an overall length around 1.290″, this bullet stabilizes well in rifles with 1:10″ to 1:9″ twist rates. The copper-alloy jacket and internal partition support roughly 60–70% weight retention, promoting consistent terminal performance and ethical shot placement.
In field applications, the 270 Cal 140gr Partition delivers controlled expansion followed by straight-line penetration, resulting in clean, ethical kills on deer, antelope, and elk-class animals—even at extended ranges. Hunters and precision shooters report stable trajectories and dependable terminal behavior, regardless of terrain or shot angle.
This is strictly a bullet component—not factory-loaded ammunition. Handloaders should consult Nosler’s official load data and trusted reloading guides. Recommended powders include Hodgdon H‑4831SC, IMR 4350, or Reloder 19, selected for their consistent velocity, safe pressure curves, and repeatable accuracy with 140‑gr .270 bullets. Proper case prep, neck tension, seating depth, and overall cartridge length are essential to optimize performance.
Combining Nosler’s proven Partition dual-core design, aerodynamic efficiency, and precision manufacturing, the 270 Cal 140gr Partition bullet component is a top-tier choice for hunters and long-range shooters seeking retained energy, terminal reliability, and accuracy in .270-caliber handloads.
