Rimmed rifle cartridges are ammunition types characterized by a protruding rim at the base of the cartridge case. This design helps the cartridge to be easily extracted from the chamber after firing, as the rim provides a surface for the extractor to grip. Rimmed cartridges are commonly used in various firearms, including lever-action rifles and single-shot rifles. These cartridges are often associated with older or traditional firearms, such as the Winchester Model 1894. Popular examples of rimmed rifle cartridges include the .30-30 Winchester and the .45-70 Government. Their design can affect feeding and extraction in semi-automatic and bolt-action rifles, making them less common in modern military applications.
