The Weatherby Select Plus .25 Weatherby RPM 117-grain Hornady SST load is engineered for hunters targeting medium-to-large big game who demand extreme accuracy and devastating terminal performance. The classic drawback of high-velocity cartridges is that soft hunting bullets can fragment or separate upon a high-speed impact, limiting penetration when it matters most. This premium load eliminates that vulnerability by locking the core and jacket together, ensuring the bullet mushrooms perfectly instead of breaking apart.
The technical advantage is found in the pairing of the legendary Hornady Super Shock Tip (SST) bullet with Weatherby's advanced Rebated Precision Magnum (RPM) case geometry. The SST projectile features a sharp polymer tip that slices through the air and drives backward into the lead core on contact to kickstart uniform expansion. To survive high-speed impact stress, Hornady's internal InterLock ring physically anchors the lead core to the outer copper jacket. This structural bond preserves the bullet's weight so it can punch deep through tough hide and bone.
Slinging a heavy-for-caliber 117-grain bullet at a blistering 3,225 FPS with 2,702 ft-lbs of muzzle energy, this system features a streamlined secant ogive profile with a 0.390 G1 ballistic coefficient that slashes drag and masterfully resists wind drift. The RPM cartridge case uses a steep 35° shoulder and minimal body taper to maximize powder efficiency within a standard-action rifle footprint, while its rebated rim fits standard bolt faces seamlessly. This creates a rock-solid, uniform pressure curve that delivers flat trajectories, exceptional velocity retention downrange, and absolute shot-to-shot consistency in the field.
Key Benefits
- Mechanical InterLock Core: Internal jacket ring locks the lead core in place, preventing jacket separation and ensuring deep penetration.
- Rapid SST Polymer Tip: Aerodynamic tip protects against magazine deformation and acts as a plunger to initiate destructive, uniform mushrooming.
- Streamlined Secant Ogive: High-efficiency bullet profile reduces mid-flight drag and wind drift for predictable long-range accuracy.
- Optimized RPM Efficiency: Smart case design packs maximum powder volume and stable burn rates into a standard short-action bolt footprint.
