This Proof Research bolt-action barrel blank is a 26-inch, carbon fiber wrapped blank built on a match-grade 416R stainless steel core and chambered for .264 Winchester Magnum. It uses an aerospace-grade carbon fiber wrap to reduce weight and improve heat transport while retaining the accuracy characteristics expected of a precision barrel. The Sendero contour and a 1:8 twist rate are specified for compatibility with long-range and precision bolt-action rifle builds.
