Hammer forging is a process in which a drilled, reamed and honed blank has the rifling formed into it by placing the barrel blank on a mandrel that has the rifling ground into its outer surface. The blank and mandrel are then placed between two opposing power hammers and the blank is beaten around the mandrel leaving the rifling pattern in the barrel. This process leaves an extremely smooth and consistent surface on the inside of the barrel, that lends itself to excellent accuracy. The forging process also work hardens the barrel steel causing a very durable and much longer lasting barrel. Their barrels have a slight taper to the bore during the hammer forging process to ensure better accuracy. Their hammer forged barrels are the best choice for shorter range, combat shooting style and high round counts.
