Weatherby Mark V Accumark .30-378 Wby Mag RH Rifle - Matte Gel Coated Black

The Weatherby Mark V Accumark in .30-378 Wby Mag is a purpose-built long-range hunting rifle engineered for shooters who demand both accuracy and durability in demanding terrain. Built on Weatherby's proven right-hand Mark V receiver, the Accumark combines a fluted stainless-steel barrel with a hand-laid fiberglass stock and aluminum bedding blocks—a platform trusted by serious hunters and range shooters tackling big game at extended distances. If you're looking for a rifle that delivers the velocity and precision of the .30-378 Wby Mag with the structural rigidity to back it up, this is your workhorse.

The Accumark's design philosophy centers on ruggedness and repeatability. The fluted #3 contour 26-inch barrel is finished in a two-tone treatment—spun stainless with graphite black Cerakote—that not only looks purposeful but sheds weight without sacrificing rigidity. The receiver, bolt, bolt knob, and safety are all coated in matching graphite black Cerakote for a cohesive, professional appearance and corrosion resistance. The hand-laid fiberglass stock features a raised Monte Carlo comb and spiderweb accent inlay, paired with a matte gel coat that resists glare and provides a secure grip in wet conditions.

Handling the .30-378 Wby Mag's substantial power requires a rifle built to last, and the Accumark delivers. The aluminum bedding blocks anchor the action securely to the stock, ensuring consistent lock-up shot after shot. With a magazine capacity of 2+1, a 1-in-10 twist rate optimized for heavy .30-caliber projectiles, and an overall length of 48.25 inches, this is a practical field rifle that doesn't feel unwieldy. At 8.3 pounds, it's substantial enough to manage recoil but light enough for a day in the hills. The 13.625-inch length of pull and well-proportioned drop at comb and heel make it natural to shoulder, whether you're behind a bench or glassing from a ridge.

The Mark V Accumark appeals to long-range hunters, competitive shooters, and anyone who refuses to compromise on repeatability. This right-hand configuration is ready to run—pair it with quality glass and ammunition, and you're set for the work ahead.
