I'm not sure why you're here, but I guess I'll tell you how a firearm works

Guns work because when you pull the trigger, the action engages. This means that the primer of the round is ignited by the hammer or striker. Once this happens, all the gunpowder in the bullet or shell ignites.

This rapid ignition causes the energy released by the burning powder to push the slug, pellets, or bullet down the barrel of the gun. What the gun powder produces is chemical energy. When that energy is transferred to the bullet, it becomes kinetic energy.

This is always accompanied by a loud bang, so make sure to wear hearing protection. You may also notice a bit of a kickback, as pressure increases in your hand and the gun jumps, or pushes your shoulder. This is recoil, it is the excess energy of the weapon firing.

The bullet then leaves the barrel, continuing on its journey downrange. If you’re firing a rifle bullet, the spin will help keep the bullet accurate. If you’re shooting a shotgun, for instance, it is a smooth bore and the slug or pellets won’t spin, but they will fly in a straight line towards the target.

As long as your aim is true, the bullet or projectile will impact the target where you wanted it to. If it doesn’t land where you wanted the first time, don’t worry, you just need to keep practicing. One of the most fun things about owning a gun is practicing your aim and shooting.
