What is the difference between Hammer Forged and Button Swaged Barrels?
Hammer forged barrels are basically squished by hammers around a mandrel as it is pushed through the bore to form the rifling. Button swaging is the process where the rifling is cut into the barrel blank by dragging a cutting tool through the barrel cutting each lan deeper and deeper with each pass.
CHF barrels are usually known for their durability and bullton rifled barrels for their consistent accuracy.
