The 6mm Lee Navy (6×60mmSR), also known as the 6mm U.S.N.[1] or .236 Navy,[2] is an obsolete American rifle cartridge.[3] It was the service cartridge of the United States Navy and Marine Corps from 1895 (therefore replacing the .45-70 Government rifle cartridge) to 1899, when it was then itself replaced by the more modern .30-40 Krag rifle cartridge.
