The grooves in the barrel.
The grooves (rifling) cut into the barrel.
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.

Rifling is the spiral groove pattern in a rifle or handgun barrel the purpose of which is to impart spin to the bullet in order to achieve stability in flight.
The barrel guides and accelerates the bullet out of the rifle, and imparts spin to the bullet to stabilize the bullet in flight.
When a bullet is fired from a rifle, a chemical reaction in the gunpowder ignites, rapidly expanding gases build up pressure, and the bullet is propelled out of the barrel at high speed. The rifling in the barrel causes the bullet to spin, improving accuracy and stability. Gravity will eventually cause the bullet to drop due to gravity and air resistance.
The bore is rifled so as to put a spin on the bullet. This spinning gives a greater accuracy to the bullet, especially over that of a smooth bore.
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.
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.
The barrel of a rifle is characterized by rifling, helical grooves that impart spin on the bullet, stabilizing the projectile in flight.
Basically, a rifle is a place to direct the explosion of gunpowder directly to the bullet to increase the efficiency of gunpowder so the bullet can travel faster, and increase the bullet's momentum so it does more damage. The rifle also is used to increase the accuracy of the bullet. By focusing the blast directly behind the bullet, the bullet is more likely to travel in the intended direction. Striations in the rifle also spin the bullet so it corkscrews forward, making the path of the bullet straighter.
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.
