A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal,[1] copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling of the barrel and forms a seal; this seal prevents the gases from blowing past the shell and engages the barrel's rifling to spin-stabilize the shell.
