5 mm/35 SMc (5mm-35) / 5x39mm SMc is a high performance 5 mm (.20 inch) intermediate cartridge. Designed by Michael McPherson and Byrom Smalley and like all of their other designs carries the "SMc" designation as well as being patented.

Description

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-inch (71 cm) 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.

The patents for the cartridge are US 7210260 , US 7086336  and US 2003079639 .
