Abstract
A cannon barrel is a conic hollow barrel cast from metal and includes two ends of different inner diameters. One of the ends of the conic hollow barrel having a relatively smaller inner diameter is secured to a cradle. A shot fired through the barrel gradually spreads while passing through the barrel. The explosion/impact area of the shot is thus enlarged, which could hit the target more easily.
