5 mm/35 SMc (or simply 5mm-35) is a high performance 5 mm (.20 inch) cartridge. Designed by Michael McPherson and Byrom Smalley[2] and like all of their other designs carries the "SMc" designation as well as being patented.[3]
SMc cartridges were developed in an attempt to produce an efficient cartridge combining low recoil, low heat, and high velocity.[4] The 5 mm/35 SMc has produced velocities in excess of 4800ft/s shooting a 30gr molybdenum disulfide-coated Berger bullet from a 28inches Pac-Nor barrel, far higher than its commercial counterpart the .204 Ruger.
Although it is a wildcat cartridge, rifles chambered for 5mm/35 are available from the custom shop at Savage Arms.[5]
The patents for the cartridge are, and .
