The Weatherby Select Plus 6.5 Weatherby Rebated Precision Magnum (WBY RPM) 127-grain Barnes Long-Range X (LRX) Copper 20-round box is a high-performance centerfire rifle cartridge engineered specifically for long-range mountain hunting, backcountry big game pursuit, and alpine game management. A primary operational challenge in backcountry hunting is balancing the carry weight of a lightweight mountain rifle against the necessity of high velocity, terminal energy retention, and dependable expansion at extended distances. Weatherby solves this dilemma through its non-belted 6.5 WBY RPM case architecture, which harnesses magnum powder capacities within a standard-length action footprint to deliver flat trajectories, high ballistic efficiency, and devastating terminal performance without excessive rifle weight.
The core technical advantage relies on the 127-grain Barnes LRX (Long-Range X) solid copper projectile. Formed from a 100% lead-free copper-alloy body with deep cutting grooves, the bullet eliminates core-jacket separation, ensuring 100% weight retention after impact. A streamlined polymer tip is engineered to resist drag and initiate rapid, reliable expansion even at low impact velocities experienced at extreme distances. Upon contact, the nose cavity opens into four razor-sharp copper petals, creating devastating wound channels while the solid shank drives deep linear penetration through heavy hide and shoulder bone.
Launching its 127-grain LRX monolithic projectile at an exceptional factory-rated 3,225 FPS muzzle velocity (generating 2,933 ft-lbs of muzzle energy), this Select Plus loading capitalizes on the 6.5 WBY RPM's 35-degree shoulder angle and rebated rim geometry. This non-belted case design ensures smooth feeding from standard bolt-face actions, tight chamber headspacing, and effortless extraction. Assembled with precision-drawn Weatherby virgin brass casings, clean-burning temperature-stable propellants, and non-corrosive match Boxer primers, the cartridge guarantees uniform velocity spreads and consistent accuracy across extreme mountain weather conditions.
