Overview
The Weatherby Mark V Accumark rifle in .338-378 Weatherby Magnum is engineered for demanding long-range applications and large game hunting. This precision rifle features robust construction and performance-driven design, providing reliable output in challenging environments.
Key Features
Precision Engineering & Materials
- Barrel: A 26-inch fluted #3 contour barrel is utilized, finished in Graphite Black Cerakote for enhanced corrosion resistance and durability.
- Stock: The hand-laid fiberglass stock, presented in a Gray Webbed Black Monte Carlo pattern, integrates aluminum bedding blocks. This design ensures a stable, consistent platform for optimal shot placement and mitigates stock flex.
Mark V Action System
- Action: At the core is the legendary 9-lug Mark V push-feed action, recognized for its robust construction. This action’s design is specifically built to manage the pressures inherent to Weatherby Magnum cartridges, ensuring operational integrity.
- Bolt: A 54-degree bolt rotation minimizes manipulation, facilitating quicker follow-up shots and enabling lower scope mounting. The forged, one-piece bolt is fluted and includes relief ports and a full shroud, enhancing user protection and operational smoothness. A reliable two-position safety mechanism also locks the bolt, preventing accidental discharge.
Trigger & Accuracy Performance
- TriggerTech Trigger: An externally adjustable TriggerTech trigger is integrated, providing a zero-creep break and minimal over-travel. This contributes directly to shot consistency and precision.
- Guaranteed Performance: Each Mark V rifle is backed by the manufacturer’s guarantee of performance: a 3-shot group of 0.99 inches or less at 100 yards (SUB-MOA) from a cold barrel, utilizing Weatherby factory or premium hunting ammunition. This ensures a verifiable standard of precision.
