Weatherby Mark V Deluxe .338-378 Wby Mag Bolt-Action Rifle - MDX01N333WR8B

The Weatherby Mark V Deluxe .338-378 Wby Mag bolt-action rifle is built for hunters who appreciate timeless design married to serious magnum performance. This rifle honors Weatherby's heritage of craftsmanship with a classic wood-and-steel aesthetic that stands apart from the modern tactical crowd. If you're after a premium hunting rifle that turns heads at camp and delivers the stopping power of one of the most potent magnum cartridges available, the Mark V Deluxe in .338-378 Weatherby Magnum is engineered for long-range big game—elk, moose, and dangerous game—where power and precision matter.

The stock is hand-selected gloss AA walnut, featuring fineline diamond-point checkering on the forend and grip cap, with rosewood and maple spacers that give it genuine presence. The barrel, trigger guard, and bolt knob wear a high-gloss finish that catches light like fine metalwork. Recoil management is handled by a Pachmayr Decelerator pad, essential given the magnum's authority. An Accubrake ST muzzle brake is factory-installed, further taming the .338-378's report and kick—a practical nod to shootability without compromising the rifle's classic lines.

Mechanically, you're looking at a 26-inch #3 contour barrel with a 1-in-10 twist rate optimized for .338-378 performance, housed in Weatherby's proven Mark V action. The magazine holds 2 rounds plus 1 in the chamber. The Monte Carlo stock geometry, with adjustable drop measurements at comb and heel, is designed to manage recoil and keep your cheek weld consistent through the shot. At 8.25 pounds and 48¾ inches overall, it's substantial enough to absorb recoil but not so heavy that it becomes a burden on an all-day hunt.

This is a rifle for the discerning hunter—someone who still believes a firearm should be as beautiful in the cabinet as it is effective in the field. The .338-378 Weatherby Magnum is no plinking round; it's a serious tool for serious distances and serious game.
