The .308 Marlin Express is a cartridge developed in 2007 by Marlin Firearms and Hornady. It is based on the .307 Winchester with a goal to duplicate .308 Winchester performance. The cartridge uses a slightly shorter, semi-rimmed case similar to that of the .220 Swift to function in lever-action rifles. As introduced in Hornady's LEVERevolution line of cartridges, it is the highest velocity production cartridge designed for lever action rifles with tubular magazines. It is chambered in Marlin's Model 308MX and 308MXLR rifles using the Marlin Model 336 action.
