PROOF BBL CF Blank Bolt .375 22" 12 Sendero Barrel

The PROOF BBL CF Blank Bolt .375 22" 12 Sendero Barrel is a precision rifle barrel blank built for custom rifle builders and gunsmiths seeking repeatable accuracy in a magnum caliber platform. Crafted by Pete Rickard, this .375-caliber barrel delivers the ballistic foundation serious long-range hunters and competition shooters demand, whether you're building a custom rifle from the ground up or replacing a worn tube on an existing action. The 22-inch length strikes a practical balance between velocity and handling—long enough to unlock the caliber's potential without excessive muzzle blast or recoil-induced fatigue during extended shooting sessions.

Built as a blank with a 12-inch twist rate, this barrel is optimized for the heavier projectiles .375 shooters typically employ. The Sendero profile delivers a moderately heavy contour that resists heat soak during rapid-fire sequences while remaining reasonable to support in a hunting rifle. At 2 pounds 16 ounces, it provides the mass needed for stability without turning your finished rifle into a bench gun. The 1.25-inch shank diameter and 3-inch breech length are standard specifications that interface with most modern bolt-action receiver designs, giving you flexibility in your build platform.

As a barrel blank, you'll need to have it chambered and finished by a qualified gunsmith—this isn't a drop-in component, but rather the starting point for a truly custom rifle tailored to your action and intended purpose. Whether you're a gunsmith stocking quality blanks or a dedicated builder who demands control over every aspect of your rifle, the PROOF BBL CF offers the precision fundamentals that translate into downrange performance.
