Cold Hammer Forging of barrels has been known for decades to
produce the most accurate, longest lasting rifle barrels obtainable. The Cold
Hammer Forging of barrels is accomplished through intense hydraulic pressure
applied at opposing angles by carbide steel hammers. During the hammering
process, a mandrel is inserted into the bore while the carbide steel hammers
shape the barrel around the mandrel creating the chamber, the lands, and the
grooves. In addition to the aforementioned benefits, the Cold Hammer Forging process
creates a defect free bore and the most consistent chamber possible.
