Gun
Cartridges' have different ways of being loaded into different kinds of weapons. Cartridges can be loaded directly into a firearm or into a 'clip', a 'magazine' or other bullet container which is loaded into the firearm. A 'clip' is loaded with rounds and the 'clip' is loaded into a weapon. The 'magazine' is a container for the rounds which has a spring that moves the bullets into place for firing. Firearms known as 'revolvers' have a cylinder with holes that the bullets are loaded into. Modern guns are usually loaded with a 'magazine' and are called 'automatic loading'.
