How many times does the gatling gun fire per minute?

Answer 1

By 1876 the Gatling gun had a theoretical rate of fire of 1,200 rounds per minute, although 400 rounds per minute was more readily achievable in combat.

By 1893, the M1893 Gatling was adapted to take the new .30 Army smokeless cartridge. The new M1893 guns featured six barrels, and were capable of a maximum initial rate of fire of some 800-900 rounds per minute.

By the 1960s, the M134 know as the Minigun is a 7.62 mm, multi-barrel heavy machine gun with a high rate of fire. It could shoot up to 4,000 rounds a minute.
