Colerain Edward Marshall profile,
37" swamped barrel,
includes flared tang plug
Our 37" swamped barrel is also called the Edward Marshall style, in honor of the 1750 era frontiersman. It may be more correct to call this an Albrecht style, after the family of gunmakers at Christian's Spring, Pennsylvania, who made transitional rifles such as Edward Marshall's rifle. The shorter Germanic Jaeger rifles evolved into America's longrifle, during this transitional period.

We offer Colerain 37" swamped barrels in 'D' profile, with taper and flare appropriate for a transitional rifle. Our price includes the breech plug, installed and match-marked. Our Edward Marshall barrel is about 1.125" at breech, .860" at waist, and 1.062" at the muzzle.

Colerain barrels are cut rifled with fancy radius groove rifling, in these correct twist rates for round balls:

  • 1 turn in 48 inch twist, in calibers .36 or .40
  • 1 turn in 56 inch twist, in calibers .45, .50 or .54
  • 1 turn in 66 inch twist, in calibers .58 or .62


    • 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 rifle 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.

    Colerain barrels are precisely profiled to fit our pre-inlet stocks, making the barrel a snap fit in our pre-inlet stock, after squaring the inside corners of our inletting, at the breech. This is a great labor saving advantage. Select a Colerain barrel, and our matching stock!
