What is the purpose of the rifling and where is it located?

Rifling refers to the spiral (helical) grooves that are cut or swagged on the internal surface (bore) of a gun barrel, which helps impart the spinning motion to a bullet when it’s fired. A spinning bullet is found to be more stable in its trajectory, and is therefore more accurate than a bullet that doesn’t spin.
