Gun barrel

The barrel of a gun or other firearm is the tube, usually metal, through which a controlled explosion is released in order to propel a projectile out of the end at great speed.

Smallbore

Generally a smallbore gun refers to a rifle or a handgun that has an inside barrel diameter of less than .243 (6mm) caliber. Specifically it refers to the 0.22" caliber as used in the Olympic rifle and pistol target shooting disciplines (Airguns of 0.277" and Shotguns of a larger bore are also have Olympic events). Allthough the projectile is relatively small and usually (for target shooting purposes) subsonic, it can travel up to one mile and although not accurate over 200m is still dangerous up to its maximum range.
