  2. Rifling a barrel involves cutting helical grooves into the inside of a metal tube to create a spiral pattern1. There are three modern methods for rifling a barrel:
    1. Cut rifling: Grooves are cut into the barrel using a cutting tool.
    2. Button rifling: A hardened steel button with grooves is pulled through the barrel to displace metal into a spiral shape.
    3. Broach rifling: A broach with grooves is pushed through the barrel to cut the grooves2.

    Rifling a barrel is a process of cutting helical grooves into the inside of a metal tube, creating a spiral pattern that imparts spin on a projectile as it travels through the barrel. This spin helps to stabilize the projectile in flight, resulting in greater accuracy.

    What is the difference between a rifling and a barrel?The differences come in with the way the rifling is put into the barrel and how the lands and grooves (high and low spots) are machined into it, and the pattern of lands and grooves. The goal of each type of rifling, no matter how it is set up, is to spin the projectile so that it rotates as it travels through the air.
    How does a rifle barrel work?For rifle barrel, it required the additional boring of grooves along the inside tube called ‘rifling.’ This set the bullet spinning as it was launched.

    How long does it take to rifle a barrel?Modern cut rifling a barrel takes at least one hour or more. The resulting barrel will be match-grade and offer sub-MOA accuracy.
