ABSTRACT:
A barrel has an inner tube with a chamber at one end and a muzzle at the other. The barrel guides projectiles such as bullets as they are accelerated by a propellant. The inner tube has an aperture near its front end. Propellant passes through the aperture into a propellant chamber formed by the inner tube and an outer tube positioned about and secured to the inner tube. A plurality of ribs extend between the inner and outer tubes. Also, a coolant may be inserted into the propellant chamber to escape through the muzzle with the propellant after the projectile exits the muzzle.
