Weatherby has created an entirely new breakthrough in rifle performance by combining their venerable, 9-lug magnum action with a stunningly-precise, carbon-fiber barrel. To make the Mark V CarbonMark a reality, the legendary American rifle maker chose the leader in carbon-fiber technology, Proof Research, to custom build their exclusive barrels chambered in .257 Wby Mag, 6.5-300 Wby Mag and .300 Wby Mag.
Adam Weatherby explains, “When looking to partner with suppliers in the outdoor industry, Proof Research was the obvious choice. They are unrivaled in carbon-fiber barrel making and we truly believe that the Mark V action, paired with a Proof Research barrel, will deliver the superior performance our customers demand.”
The aerospace-grade carbon fiber in the Mark V CarbonMark barrel has a specific strength up to 30 times stronger than stainless steel, and a specific stiffness up to 7 times stiffer. It makes the barrel up to 64% lighter than traditional steel barrels of the same contour. Carbon-fiber technology also improves heat dissipation for cooler, more consistent performance; reduced point-of-impact shift during high-volume fire; and diminished harmonic barrel vibration. The 26” #4 contour carbon-fiber barrel has a cut-rifled, hand-lapped 416R grade stainless steel core with a flush thread cap and 5/8-24 muzzle threads for easy suppressor installation. It’s finished in tactical grey Cerakote for incredible durability.
Not surprisingly, the Mark V CarbonMark carries Weatherby’s SUB-MOA accuracy guarantee that promises .99” or less 3-shot groups at 100 yards when used with Weatherby factory or premium ammunition. This is something the innovators at Proof Research are equally enthusiastic about. Kelly Streiff, Director of Sales and Marketing at Proof Research, says “With the craftsmanship and legacy of Weatherby, combined with technical advancements of Proof Research barrels, the CarbonMark redefines the modern-day hunting rifle.”
Like other Weatherby Mark Vs, the CarbonMark comes standard with an LXX trigger for a crisp, precise pull that’s critical for long-range accuracy. It also has a fluted bolt body, integral recoil lug, and a 54-degree bolt lift for fast, smooth cycling.
The stock ensures a seamless union between rifle and shooter with its raised-comb Monte Carlo design, right-side palm swell and Pachmayr Decelerator recoil pad. For light weight and a perfect marriage with the Proof Research barrel, the stock has an aluminum bedding block and is crafted from hand-laminated composites. The matte gel-coat finish provides stealth on every hunting adventure.
