Weatherby Mft01N378Wr6B Mark V Frontier 378 Wby

The Weatherby Mark V Frontier in 378 Wby is a serious big-bore rifle built for hunters who need genuine stopping power on the largest game. This rifle sits on Weatherby's time-tested Mark V action—one of the most respected platforms in magnum rifle shooting—and chambers one of the company's most potent cartridges. If you're hunting elk, moose, or dangerous game and want a rifle that combines raw power with reliable field performance, the Frontier delivers both.

The Mark V Frontier balances toughness with refinement in ways that matter in the field. The barrel, receiver, trigger guard, bolt, bolt knob, and safety are all finished in Graphite Black Cerakote—a hard, durable coating that resists corrosion and wear without fuss. The real eye-catcher is the exhibition-grade walnut Monte Carlo stock with a matte finish. That's not decorator veneer; it's genuine walnut shaped for a classic, hand-crafted look that doesn't sacrifice ergonomics or control.

Chambered in 378 Wby, this rifle is engineered for fast follow-up shots when they count and the inherent control you need to manage recoil effectively in the field. The Mark V action's reputation for reliability under extreme pressures means you get consistent performance in tough hunting situations. Whether you're glassing from a ridge or moving through timber, the Frontier is built to perform without flinching and handle the demands of serious hunting.
