The design feature that causes a bullet to spiral, which increases accuracy and distance, is called what?

Rifling is a crucial design feature in firearms that enhances the accuracy and distance of a bullet. It refers to the spiral grooves cut or formed into the bore of a gun barrel. These grooves impart a spin to the bullet as it travels down the barrel when the gun is fired. This spin stabilizes the bullet's flight path, reducing wobbling and helping it maintain a straighter trajectory over longer distances. The consistent spin from rifling allows for improved precision, making it easier for hunters and marksmen to hit their intended targets.

This design is important in achieving a more effective and reliable shooting performance, especially at various ranges. Without rifling, bullets would tend to tumble in flight, making them less accurate. Thus, the presence of rifling is vital in modern firearms for effective shooting.
