The Weatherby Mark V Accumark 338-378 Wby Mag pairs Weatherby’s flagship Mark V action with a fluted #3 contour, 26 inch two-tone stainless barrel capped by the factory Accubrake ST muzzle brake. The graphite black Cerakote receiver and hand-laid Monte Carlo fiberglass stock with gray spiderweb accents create a durable, weather-ready rifle that still carries Weatherby’s Sub-MOA accuracy guarantee. A crisp TriggerTech Field trigger and 54 degree bolt lift round out a package built for confident long-range shooting.

This Mark V Accumark is purpose-built for hunters who need flat trajectories and serious downrange energy on big game at extended distances. Its 2+1 capacity, 8.3 pound weight, and raised comb stock help manage the stout .338-378 Weatherby Magnum while maintaining control from field positions. Ideal for open-country hunts where shots stretch across canyons or tundra, it reflects Weatherby’s long-standing reputation for precision, reliability, and thoughtful craftsmanship.
