When the bullet is fired, the air passes through these curved grooves and spins the bullet. High pressure gases exert forces on the back of the bullet and on the gun. In this instance, the "gun" is part of a nuclear weapon and contains an explosively propelled sub-critical slug of fissile material within a barrel to be fired into a second sub-critical mass in order to initiate the fission reaction.
