Imparting spin to projectiles without fletching is a technique used to stabilize and improve the accuracy of projectiles. Fletching, the process of attaching feathers or vanes to the projectile, is traditionally used to induce spin and maintain stability during flight. However, there are alternative methods to achieve spin without the use of fletching.
One method involves the use of rifling, a series of spiral grooves cut into the bore of a firearm barrel. As the projectile travels through the barrel, it engages with the rifling, imparting a spin that stabilizes its flight. This principle is commonly employed in firearms and artillery.
