The Weatherby Select Plus .25 Weatherby Rebated Precision Magnum (.25 WBY RPM) 133-grain Berger Elite Hunter 20-round box is an ultra-performance centerfire rifle cartridge engineered specifically for extended-range big game hunting in demanding, open-terrain environments. A severe historical friction point with traditional .25-caliber platforms is their mechanical inability to stabilize long, high-BC projectiles due to outdated, slower barrel twist rates, which limits ethical shot placement and downrange energy retention. Weatherby eliminates this ballistic bottleneck by pairing their modern .25 RPM cartridge case with a heavy-for-caliber 133-grain Berger Elite Hunter projectile, optimized for fast 1:7.5" twist barrels to maintain absolute flight stability and maximum terminal effectiveness.
The technical advantage focuses on an elite projectile geometry that blends the best characteristics of tangent and secant bullet profiles. Launching this massive 133-grain payload at a powerful muzzle velocity of 3,000 FPS, the cartridge boasts an extraordinary 0.613 G1 ballistic coefficient to cut cleanly through erratic crosswinds. Mechanically, the Berger hybrid ogive minimizes downrange aerodynamic drag while remaining highly tolerant to cartridge seating depth variations, ensuring match-grade consistency across different rifle chambers. Wrapped in a J4 precision hunting jacket, the bullet is designed to penetrate two to three inches past thick hide and bone before the thin nose section initiates rapid, catastrophic internal fragmentation for a massive dumping of kinetic energy.
Slinging its heavy 133-grain hybrid projectile at 3,000 FPS, this load delivers a remarkably flat trajectory that retains devastating downrange energy for clean, ethical harvests in variable alpine conditions. The advanced .25 WBY RPM case utilizes a non-belted, modern design featuring a sharp 35-degree shoulder and a rebated rim. This allows the cartridge to hold a massive propellant payload and feed flawlessly through standard long-action rifle magazines without requiring an oversized magnum bolt face or receiver action. Built with factory-fresh premium brass and ultra-stable primers, the entire system ensures dynamic chamber sealing, consistent ignition, and glass-smooth extraction.
Key Benefits
