Imparting spin to projectiles with out fletching is a way used to stabilize and enhance the accuracy of projectiles. Fletching, the method of attaching feathers or vanes to the projectile, is historically used to induce spin and preserve stability throughout flight. Nevertheless, there are various strategies to attain spin with out using fletching.
One technique includes using rifling, a sequence of spiral grooves minimize into the bore of a firearm barrel. Because the projectile travels by the barrel, it engages with the rifling, imparting a spin that stabilizes its flight. This precept is usually employed in firearms and artillery.
