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.

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.
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 causes spin in a projectile during its projectile motion?
The spin is forced on to the bullet or shell by grooves in the gun barrel, this is to take advantage of the fact that the axis of a rotating object will tend to remain parallel, this , in effect keeps the shell or bullet in a good aerodynamic profile, without tumbling (which absorbs energy). These grooves are known as rifling and so any weapon which has those grooves in the barrel is said to be rifled.
What causes turbines to spin in hydroelectric power?
Heat
What energy causes blades to spin?
Rotational energy
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.
What causes a bullet to spin from a rifle or handgun?
The grooves in the barrel.
What is purpose of rifling in a firearm?
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.
What causes the bullet to spin froma rifle or handgun?
The grooves (rifling) cut into the barrel.
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.
Does rifling cause the bullet to rise?
It can. The rifling in the barrel causes the bullet to spin. This usually keeps the bullet moving relatively straight (because of gyroscopic stabilisation). However, as the bullet slows down at longer ranges, the spinning can cause it to wobble and drift. This is called spin drift. Spin drift can be upwards, so yes, rifling can cause a bullet to go up, but only at extreme ranges.
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.
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 causes a bullet to spin when fired?
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.
What part makes bullet spin on hand gun?
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.
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.
