What are the Grooves Inside The Gun Barrel?

When cleaning your handgun, semiautomatic rifle or other firearms, you will notice grooves inside the barrel. New gun owners often notice them when using a bore brush for the first time when cleaning the barrel. The grooves inside your gun barrel are a crucial part of how a gun works; the grooves put a spin on the bullet as it travels the length of the barrel after you've pulled the trigger. That spin helps the bullet travel straighter and more aerodynamically. In order to hit your target, the bullet must fly in a straight line, with as little wobbling as possible. The grooves in the barrel help the bullet to do that; the bullet is forced into a proper spinning motion to start the journey right.

The grooves in your gun barrel are scientifically designed to provide specific spin rates for your ammunition. The grooves are precise; too little spin on a bullet causes it to start tumbling once it leaves the barrel but too much spin and the bullet can disintegrate before it strikes the target. Just the right amount of spin is a vital part of how a gun works.
