Key Features
Mark V Action System
The core of this rifle is the Weatherby Mark V 9-lug bolt action, a design recognized for its strength and rapid lock time. The nine-lug system ensures robust lockup, essential for containing the pressures generated by magnum cartridges. Its short 54-degree bolt throw facilitates swift, unobstructed cycling for rapid follow-up shots while maintaining a low scope profile. This action provides consistent ignition and positive cartridge extraction under demanding field conditions.
.338-378 Weatherby Magnum Caliber
Chambered in .338-378 Weatherby Magnum, this rifle is optimized for maximum energy transfer and flat trajectory at extreme ranges. This cartridge delivers superior ballistic performance, making it an optimal choice for large, dangerous game and long-distance precision shooting where kinetic energy retention is critical.
Precision Barrel Integration
The 26-inch free-floating barrel is crucial for maintaining consistent accuracy. Its length is optimized for the .338-378 Weatherby Magnum, allowing for complete powder burn and maximizing muzzle velocity. This precision manufacturing, combined with the Mark V action, contributes to the rifle’s inherent accuracy, backed by Weatherby’s sub-MOA accuracy guarantee with premium ammunition.
Deluxe Walnut Stock
The Mark V Deluxe features a high-grade, oil-finished walnut stock with a Monte Carlo comb and fine-line checkering. This traditional design provides both ergonomic handling and a classic aesthetic. The stock integrates a Pachmayr Decelerator recoil pad to mitigate the significant recoil generated by the .338-378 Weatherby Magnum, enhancing shooter comfort and control.
Adjustable Trigger System
Equipped with the Weatherby LXX Trigger, this rifle offers a fully adjustable pull weight, facilitating precise shot placement. The crisp, clean break characteristics of this trigger system allow the shooter to maintain optimal sight picture and minimize unintended movement during the firing sequence.
