.366 TKM is a rifle cartridge developed from the Soviet 7.62x39mm. .366 TKM was developed for the Russian civilian market, where smoothbore firearms are considered shotguns. Despite being a smoothbore cartridge it is still very capable, some loading such as the Deri and Geksa loads outperform 7.62x39 greatly.
