Geo, a cartridge is the complete unit made up of a casing that holds a projectile in front of an explosive charge. The first cartridges, used on muskets were blackpowder and a lead ball wrapped tightly in paper. The end of the cartridge was bitten off and dumped onto the barrel powder-first. Then primered cartridges were developed that contained a priming charge to ignite the powder charge in the cartridge. After much experimentation, the standard cartridge became a metal case with the primer at the rear of the cartridge, as with modern ammunition.
The term clip is sometimes used to refer to a spring-loaded box (<==magazine) that feeds cartridges into the receiver of a firearm. But clip more accurately refers to the stripperclips that were used to rapidly, albeit manually, feed cartridges into the built-in magazine found in a great many firearms. Examples of this would be the Mauser model98, the Springfield Model1903, and the M1 Garand. The Garand rifle's clip differed somewhat from traditional clips in that it was inserted into the magazine along with the cartridges it contained. Up until that time, the clip was inserted into a fitting or notch in the receiver and the rounds were stripped from it into the magazine with a push of your thumb, hence stripperclip. During late WWI and throughout World War II more benefits were found in the use of detachable magazines, which became the standard method of feeding modern military weapons. In familiarity, 'detatchable magazine' was shortened to just magazine.
