Spiral grooves cut into the inside of the barrel- known as rifling.
Rifling causes the bullet to spin through the barrel and downrange. This spin stabilizes the bullet, allowing it to maintain a straight course to the target. Without the spin, accuracy would be dismal.

Yes, bullets do spin when they are fired. This spinning motion, known as rifling, helps stabilize the bullet's flight path and improve accuracy.
Two to six, depending on the make, model, and type of firearm.

It will depend on the firearm and the exact markings on the barrel.
its when you have a gun or any weapon that fires bullets.
Bullets spin when fired from a gun because of rifling, which are spiral grooves inside the gun barrel. The spinning motion stabilizes the bullet's flight, improving accuracy and range.
Because of the rifling inside the barrel. If you want to know the purpose of that, the answer is, it causes the bullet to travel farther and more accurately, just like when you throw a football.
Rifling in the barrel is actually grooves cut into the barrel by the manufacturer to cause the bullet to spin as it leaves the barrel. Before rifling the bullets would tend to tumble when they left the barrel causing them to have shorter range and be less accurate.
To make bullets spin so they fly straight.
