38in
Colerain Barrels are drilled from solid bar stock, using a radius 6 lands and grooves rifling of .012 deep for 40 caliber and .016 on all others. This produces round bottom grooves which promotes less fouling and easier loading and cleaning. All barrels have crowned muzzles for loading ease and come with installed breach plug.
The Fowler Smoothbore Octagon to Round is a 38″ barrel which is excellent for a Fowler. 20 gauge; C weight.
