Colerain rifle barrels are the favorite choice of today's best muzzle loading gun makers, because knowledgeable shooters demand Colerain's accuracy, inside and outside.

Founded by two entrepreneurs, Scott Keller and Scott Kelly were tutored by Bob Paris, the famous rifle barrel maker who was first to perfect the technique for production of correct swamped barrels.

Colerain barrels are drilled from solid steel, cut rifled .012" to .016" deep depending on caliber, with six "round bottom" grooves. Called "radius groove rifling", Colerain eliminates the sharp inside corner that accumulates fouling. Radius groove rifling cutters are a bit more expensive to make, but Colerain's customers agree that the accuracy, easy loading, and easy cleaning are worth the cost.
