The Weatherby Select Plus .270 Weatherby Magnum 150-grain Nosler Partition Soft Point (SP) Brass 20-round box is an elite centerfire rifle cartridge engineered specifically for long-range big game hunting where ultra-flat trajectories and deep terminal penetration are required. A common friction point with high-velocity magnum cartridges is bullet breakdown upon impact, where standard soft points expand too rapidly or fragment at close range while failing to drive deep through heavy tissue at extended distances. Weatherby resolves this terminal challenge by loading Nosler's legendary dual-core Partition projectile, which mechanically isolates expansion from weight retention to deliver reliable, lethal penetration across extreme velocity spreads.
The core technical advantage relies on the structural copper partition built into the center of the 150-grain projectile. Upon target impact, the forward lead core undergoes immediate, controlled expansion facilitated by a thin, tapered jacket wall. The internal solid copper wall halts that deformation, protecting the heavy rear lead core to guarantee high retained bullet mass and straight-line penetration through tough hide, dense muscle, and heavy bone structure. Boasting a heavy 0.279 sectional density, the projectile maintains high downrange momentum to crush vital organ zones.
Launching its 150-grain partition projectile at a blistering 3,245 FPS from the muzzle, this magnum load flattens trajectory curves for minimal holdover adjustments when taking extended shots in open country. Assembled in premium, precision-drawn Norma virgin brass cases with non-corrosive Boxer primers and temperature-consistent propellants, it maintains stable chamber pressure and repeatable shot-to-shot velocity. It is a premier choice for elk, mule deer, caribou, and bighorn sheep across big country terrain.
