At 1869, engineer Zagoskin constructed a 8-barrel "lightweight" Gatling gun, in weight of standart .42 Berdan Gatling gun, but, used a special .60 cal cartridge. Weight of bullet 72.5 g (1119 gr), weight of propellant charge 17 g (262 gr). This gun tested at 1869-1871. Project closed due to cartridge problems - case blowouts, etc. Works at "lightweight" Gatling guns used by engineers Gorlov and Baranovskiy, to create a M1871 (Gatling-Gorlov) and M1873 (Gatling-Baranovskiy) machine guns.
In 1871, considered the idea about small-caliber "grenade cannon" - actually, 1.5 inch Gatling gun with exposive bullets - for use in Army. "Soldiers, splattered with the blood and brains of their friends, can be demoralized..." (from real documents). Suggest of use buck cartridge for short distance, 15 bullets in shot, rate of fire - from 40 to 60 rpm. Range for use of buck - 200 sazhen (one standart sazhen = 7 british foots, or 213.36 cm, 200 sazhen = 427 m), for grenades - 600-700 sazhen (1280-1493 m). I haven't data about create of special grenade cartridges for this gun, but, in Russian army used exposive bullets with powder, Pankratov M1854, and other bullets, two or more types, in 1860th. In Pankratov bullet use a nail with cut shaft and one pistol. Later, created Ushakov bullet, with two pistons and central core.

Bourgeous Dubinin at 1883 suggest a "buck gun", big 8-barrel shotgun, with fan-shaped firing, with 50 bullets in one cartridge, rate of fire - 1600 bullets per minute, or, 32 rpm.
Engineer Wilner at 1880 suggest a volley gun, with 2500 .42 cal Berdan barrels.
General V. L. Chebishev (Rus. Чебышев) at 1885 constructed unknown "lightweight" 6-barrel Gatling gun.
At 1898, after death of General E. K. Adasovskiy, his widow transferred a "rifle-mitraliese" (Original, Rus. "Ружьё-митральеза") to unknown museum.
