<P> In firearms , rifling is the helical groove pattern that is machined into the internal ( bore ) surface of a gun 's barrel , for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting . This spin serves to gyroscopically stabilize the projectile by conservation of angular momentum , improving its aerodynamic stability and accuracy over smoothbore designs . </P>
