By definition, Centerfire rounds have a primer located in the center of the cartridge case head that is a separate, replaceable component. Unlike Rimfires, which are ignited from the “Rim” and consist of fewer components, Centerfire rounds are ignited when the explosive primer, located between the cup and anvil components, is struck. Edward M. Boxer is credited with modern primer designs with origins dating as far back as 1866.
