The Proof Research Competition Barrel (brand part no. 113707) is a 28-inch stainless steel bolt-action barrel chambered around .243 caliber, built in Proof’s Competition contour for long-range precision and F-Class style shooting. A 1-in-7.5 twist rate stabilizes the long, high-BC bullets favored in .243 competition loads, and a 1.25-inch shank diameter is machined to fit standard bolt-action receiver specs. At roughly 7 pounds 14 ounces, the Competition contour carries the mass long-range shooters want for a stable, front-heavy rifle that settles quickly between shots. This barrel is sold unfinished at the chamber end for a gunsmith to headspace and fit to a specific action.
