The rifling in the barrel. These are grooves cut on the interior of the barrel that twist around and cause the bullet to spin as it passes down the barrel. The spin stabilizes the bullet and promotes accuracy.

What is the difference between a rifle and a gun?
Gun can refer to a long gun or a hand gun. A rifle is very particular. It has to have grooved barrel which spin the bullet when it is going down the barrel. This spin action on the bullet makes it more accurate.
Why does a bullet spin?
The answer has two parts - 1. Why do you want it to spin: It allows the bullet to be more accurate and travel further. The bullet spins for the same reason that football players spin a football when they throw it. 2. Why does it spin (How do you make it spin): Inside the barrel are grooves (rifling) that catch part of the lead of the bullet and spin it like bolt spins when you put it into a nut.
What is left hand twist and right hand twist with rifled barrels?
The direction of the spin which is put on the bullet by the rifling.
What are the purpose of rifling in the gun?
The purpose is to make the bullet spin as it leaves the rifle. The spin makes the bullet travel in a straight line, and allows for accurate shooting at longer distances.
Bullet spin when shot from a rifle or handgun what causes the spinning?
Rifling. The barrel is not smooth on the inside. There are small grooves spiraling down the barrel which makes the bullet spin. Nearly all shotguns do not have rifling in the barrel.
The main purpose of rifling features in a gun barrel is to?
It causes the bullet to spin which makes it go straighter.
What direction does a bullet spin?
Direction of spin is dependent on the direction of the rifling on the inside bore of the barrel. A bullet will spin the same direction as the rifling.
What is ballistic spin drift?
Ballistic spindrift is when the spin imparted on the bullet causes a drift in the direction the TOP of the bullet is spinning in.
Why does a gun put spin on it's bullet when the gun is fired?
Because a spinning bullet travels in a straighter line, for further, than a bullet which is not spinning. So, in a word, "accuracy" is why a gun puts a spin on a bullet. Not all of the guns put spin on the bullet though. Those that do have rifled barrels(grooved on inside). There are also smooth bore guns that do not cause the projectile to spin.
What makes a bullet spin?
The barrel of the gun has lands and grooves (grooves and ridges) cut in a spiral. The bullet molds to these and starts to spin as it moves down the barrel. The bullet just continues to spin after it leaves the barrel.Correct. The ridges are known as 'lands'. It is possible to calculate how fast a bullet will spin if you know the twist rate of the barrel and the velocity of the bullet. My AR15 has a twist rate of 1-in-8 ie for every eight inches the bullet travels down the barrel, the bullet is rotated once. It fires a .223 round at approx 2,800 feet per second so... The formula is (bullet velocity x 720)/twist rate so... (2,800x720)/8 is an incredible 252,000RPM!
What effect does rifleing in the barrel of a gun have?
It makes the bullet spin when it is fired- much the same way a football spins in flight. The helps the bullet travel in a straight line, improving the accuracy of the gun.
What causes a bullet to spin?
There are spiral grooves engraved on the inside of a rilfe or pistol barrel. When a bullet is fired, it is forced into those grooves, which impart a spin to the bullet. The grooves are called rifling.
