Description
editSMc 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 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.[5]
The patents for the cartridge are US 7210260, US 7086336 and US 2003079639.
