9x39mm

9x39mm cartridge was designed in the late 1980s for use in special-purpose suppressed rifles. Originally said rifles were supposed to utilize subsonic 7.62x39 rounds, but eventually its terminal performance was deemed unsatisfactory and bullet diameter was increased. 9x39 is moderately powered short-range round, good for its intended niche.
