Gun barrel steel grades6/11/2023 ![]() The barrel maker must choose the type of steel the barrels are made from. Usually pistol barrels are the only type broached. Broaching is a quicker method but requires more expensive tooling. ![]() Cut rifled barrels can be either single point cut, one groove at a time, or they might be broached. The button can either be pushed or pulled through the barrel. Within the realm of buttoned barrels there are two methods of manufacture. Since my experience is mostly with buttoned barrels, I’ll probably seem a little biased towards that method. However, I haven’t seen a barrel made by this process that looked to be of suitable quality for match shooting. There also has been some work being done with chemically rifled barrels, similar to an EDM process. There is no loss here though, because generally speaking the quality of a buttoned or cut rifled barrel is superior to the forged types. ![]() The capital investment required to hammer forge barrels is high, keeping it out of the reach of smaller makers. Large manufacturers also may choose to hammer forge barrels. Hopefully I won’t reveal anyone’s “secrets”, either.įor the smaller custom barrel makers, there are two basic types of rifling methods to choose from: button rifling and cut rifling. I will attempt to do so without getting too technical.
