The CZ-550 is a bolt-action hunting rifle series manufactured by Česká Zbrojovka Uherský Brod (CZ). The CZ 5005 series is available with a medium or magnum sized action. The CZ 550 rifle resembles the Mauser 98 rifle series, though it is not an exact copy. Since the CZ 550 magnum size action can be chambered for super magnum cartridges some elephant gun wildcat cartridges were tested (see .585 Gehringer) and others specially designed (see .600 Overkill) with and for this action.
