The Proof Research Stainless Bolt-Action Barrel (brand part number 113714) is chambered for .243-caliber cartridges and machined to a 28-inch length with a competition contour, giving precision shooters the rigidity and heat management needed for extended strings of fire without excess weight. A 1:7 twist rate stabilizes heavier, high-BC 6mm-class bullets, and a 1.25-inch shank diameter mates to standard bolt-action receivers. At roughly 7 pounds 12 ounces, it strikes a balance between the stiffness competition shooters want and a barrel that is still practical to carry and handle.
