However, there is a bit more to it than just drilling a straight hole from one end to the other. Notice that I said a straight hole.

Are gun barrels hardened?

Whatever the type of steel chosen, the most important characteristics of the steel are ease of machining, longevity and strength. A tradeoff is made between tensile strength and impact strength and therefore, the barrels are hardened to between 25 and 32 on the Rockwell C hardness scale.

Do handguns have barrels?

The handgun has a short barrel with rifling and thick walls to withstand high pressures. Because of the short barrel, extra care must be taken to control the muzzle of a handgun. Like the rifle, rifling in the handgun puts a spiral spin on a bullet when fired, increasing accuracy and distance.
