History

In the early 1930s, it was decided to develop a large-caliber hunting cartridge with an expanding bullet and a hunting rifle for this cartridge based on the design of well-known standard military rifle. In 1932, Tula Arms Plant began serial production of the NK-8,2 mm hunting carbine,[1] which lasted until 1941.[2]

After the end of World War II, production continued, with the weapon being renamed KO-8,2.[2][4][3]

After start of the serial production of new hunting rifles (Bars, Los and Medved), the production of KO-8,2 hunting carbines and 8.2×66mm cartridges for them was discontinued.[2]
