The Berdan rifle (Russian: винтовка Бердана) is a single-shot rifle created by American engineer and inventor Hiram Berdan in 1868. It was the service rifle of the Imperial Russian Army from 1870 when it replaced the Krnka to 1891, when it was replaced by the Mosin–Nagant rifle. The gun was widely used in Russia as a hunting weapon, and sporting variants, including shotguns, were produced until the mid-1930s. The Russian Berdan I (M1868) and Berdan II (M1870) rifles of .42 caliber are distinct from the Spanish Berdan 15 mm (0.591 in) conversion rifles adopted by Spain as the M1857/67 Berdan (and related engineer, artillery & short rifles).
