For instance, air guns can be used for target practice training, recreational purposes, small game hunting, vermin control, and more. While traditional firearms use a small explosion to propel a projectile (ammo) out of a barrel, an air gun uses compressed air to force the ammo (metal bb or pellet) out of the barrel. There are several methods for doing this. Powerful springs, gas pistons, CO2 cartridges and high-pressure air tanks are some of the more common methods in airgun powerplants. Add in the variety of calibers to choose from, including .177 & .22 caliber (the most common) up to .45 & .50 caliber (powerful big bore), you can see why this type of gun continues to grow in popularity.
