The Nosler Trophy Grade .25-06 Remington 100-grain Partition® Spitzer Soft Point (SP) Brass 20-round box is a high-velocity centerfire rifle cartridge engineered specifically for medium big game hunting, long-range pronghorn management, and deer control. A primary friction point when shooting high-velocity .25-caliber hunting ammunition is bullet fragmentation and jacket separation upon close-range impact, or insufficient terminal penetration when encountering heavy shoulder bone. Nosler resolves these dual velocity limitations by pairing its fully prepped reloadable virgin brass cases with the world-renowned 100-grain Partition® Spitzer Soft Point bullet, delivering ultra-flat trajectories, rapid terminal expansion, and guaranteed weight retention across variable impact distances.
The primary technical advantage centers on Nosler’s legendary 100-grain Partition® projectile design. Featuring a dual-core architecture separated by an integral internal copper alloy web, the bullet mechanically limits deformation depth. The forward lead core enclosed in a thin, fully tapered jacket initiates immediate, mushrooming expansion upon hydraulic contact, transferring immense hydrostatic shock into vital organs. Meanwhile, the heavy rear lead core remains protected behind the solid copper wall, preserving structural integrity and weight retention to drive straight, deep penetration through thick hide and dense bone structure.
Launching its 100-grain Spitzer SP projectile at a blistering 3,300 FPS muzzle velocity, this Trophy Grade loading maximizes the case capacity of the .25-06 Remington to provide an exceptionally flat trajectory, short time-to-target, and minimal crosswind deflection. Assembled using Nosler’s custom prepped virgin brass cases—which are weight-sorted, length-trimmed, and chamfered—alongside clean-burning propellants and non-corrosive Boxer primers, the round guarantees uniform chamber pressure curves and smooth feeding across standard long-action bolt rifles. It stands as an outstanding choice for whitetail deer, mule deer, pronghorn antelope, and blacktail.
Key Benefits
- Partition® Dual-Core Bullet: Forward core expands rapidly for lethal shock, while the solid rear core preserves mass for deep penetration.
- Integral Copper Alloy Web: Structurally limits bullet expansion to prevent jacket-core separation on high-velocity bone impacts.
- 3,300 FPS High Velocity: Delivers ultra-flat flight paths and high energy transfer to minimize holdover error across open country.
- Custom Prepped Nosler Brass: Fully trimmed, chamfered, and weight-sorted brass ensures reliable ignition, tight tolerances, and long reloadable life.
