Weatherby Mark V Accumark 338-378 Wby Mag 26" Barrel Rifle

The Weatherby Mark V Accumark 338-378 Weatherby Magnum delivers exceptional long-range performance with its precision-engineered action and premium barrel construction. This magnum rifle combines Weatherby's legendary accuracy with modern materials to handle the most demanding hunting situations. The 338-378 cartridge provides devastating terminal performance at extended ranges where other calibers fall short.

What Makes This Different

The Mark V Accumark features a hand-lapped, free-floating barrel that maintains sub-MOA accuracy even with magnum pressures. Unlike standard hunting rifles, the Accumark utilizes a precision-bedded action with nine locking lugs that distribute bolt thrust evenly for enhanced accuracy. The graphite black Cerakote finish provides superior corrosion resistance compared to traditional bluing, while the fluted barrel reduces weight without sacrificing rigidity.
