For what purpose do rifled barrels put a spin on a traveling bullet?

Question

Does it give it some sort of added benefit like traveling further vs no spin? Why does that happen physics wise?

Answer 1

Objects that spin are more stable. Look at a children’s toy like a top, or a gyroscope. Applying that to a bullet will improve its accuracy and keep it pointing in the direction it was fired, as opposed to spinning out through the air.

For a cool demonstration, check out the Slo Mo Guys firing [*tank shells*](https://www.youtube.com/watch?v=xpJ8EoGmLuE) where the tank’s barrel gives them that spin.
