List of rifle cartridges, by category, and then by name. Because this is a very extensive list categories have been added to make searching easier. Within each category, cartridges are organized by name and split into groups with names based on inches and names based on metric measurement. The Common Centerfire category is meant to cover rounds that are either in production for commercial or military use, or are still frequently used / talked about / known.
