The Weatherby Mark V BC Guide in .257 Weatherby Magnum is engineered for the serious hunter operating in rugged, demanding environments. This bolt action rifle integrates advanced material science with the proven Mark V action to deliver a lightweight, durable, and exceptionally precise platform. It is designed to optimize performance where minimal weight and absolute reliability are paramount, enabling confident shot placement under strenuous field conditions.
Key Features
Mark V Action
The heart of the BC Guide, the Weatherby Mark V action, features a robust 9-lug design optimized for standard calibers. This system provides a significantly larger locking surface area for enhanced strength and safety under high chamber pressures. The 54-degree bolt throw facilitates rapid cycling and mitigates interference with mounted optics, ensuring swift and positive follow-up shots.
Carbon Fiber Stock
Constructed from a lightweight carbon fiber composite, the stock significantly reduces the rifle’s overall mass without compromising structural rigidity. Its ergonomic design provides a stable shooting platform, enhancing control and reducing felt recoil, crucial for extended periods of carry and precision shot placement in variable field positions.
Fluted Stainless Steel Barrel
The 24-inch fluted stainless steel barrel is engineered to maintain accuracy across varied shot strings. Fluting reduces weight and increases surface area for improved heat dissipation, mitigating point-of-impact shift during sustained fire. Its precise contour and material selection contribute to the rifle’s inherent accuracy and superior corrosion resistance. The muzzle is threaded and equipped with an Accubrake ST Muzzle Brake to further mitigate felt recoil and muzzle rise.
Match-Grade Trigger
Equipped with a user-adjustable, match-grade LXX trigger, this rifle offers a crisp, consistent break, enabling precise shot execution. The trigger system is factory-set to optimize pull weight while maintaining critical safety parameters, ensuring a clean release with every shot.
SUB-MOA Precision Guarantee
Weatherby backs the Mark V BC Guide with a factory SUB-MOA (Minute-of-Angle) precision guarantee. This commitment assures that the rifle will consistently produce groups of 0.99-inch or less at 100 yards with premium ammunition, validating its capability for surgical shot placement.
257 Weatherby Magnum Caliber
Chambered in the high-velocity .257 Weatherby Magnum, this rifle leverages one of the flattest-shooting cartridges available. Its exceptional ballistic performance is ideally suited for long-range engagements on medium-sized game, delivering superior energy transfer and a minimized trajectory arc to optimize terminal performance.
