5 mm/35 SMc is a high performance 5 mm (.20 caliber) cartridge. Designed by Michael "Mic" McPherson and Byrom Smalley and like all of their other designs carries the "SMc" moniker as well as being patented and having a copyright.
SMc cartridges were developed in an attempt to produce an efficient cartridge combining low recoil, low heat, and high velocity. The 5 mm/35 SMc has produced velocities in excess of 4,800 ft/s (1,500 m/s) shooting a 30-grain (1.9 g) molybdenum disulfide-coated Berger bullet from a 28 inches (71 cm) Pac-Nor barrel, far higher than its commercial counterpart the .204 Ruger.
