The expanding gas forces the bullet out of the cartridge and down the barrel with great speed. The rifling in the barrel causes the bullet to spin as it travels out of the barrel. The bullet’s speed and escaping gases produce a “bang.”
Why do bullets rotate?
The bullet spins on its axis due to the rifling inside the barrel of the firearm. Rifling refers to a series of ridges (lands) and grooves inside the barrel. Upon firing, a tight-fitting projectile resists being forced against the ridges and as pressure builds it has to rotate in order to move forward under pressure.
Which feature of a barrel puts a spiral spin on the bullet?
The ridges of metal between the grooves are called lands. Together, the grooves and lands are called rifling. When a handgun is fired, the rifling in the barrel puts a spiral spin on the bullet. This spin keeps the bullet point-first in flight, increasing accuracy and distance.

Does a spinning bullet travel faster?
The direction of the spin doesn’t matter. Now a spinning bullet will travel faster, farther, more accurate, and with more energy when it strikes the target than a non-spinning bullet. Spinning makes the bullet travel in a straighter path, but it also causes the bullet to meet less air resistance when traveling.
