A drum magazine is a type of magazine that is cylindrical in shape, similar to a drum. A magazine is an Ammunition storage and feeding device within or attached to a repeating Firearm. The drum is a member of the percussion group technically classified as a Membranophone. In a drum magazine, rounds are stored in a spiral around the center of the magazine. The advantage over traditional box-shaped magazines is that a drum magazine can carry much more ammunition, often twice that of a box magazine, such as the 71-round drum for the Russian PPSh-41 submachine gun without making it too big to be impractical to carry. The PPSh-41 ( P istolet- P ulemyot Sh pagina; Пистолет-пулемёт Шпагина; Shpagin Machine Pistol; nicknamed The downside to drum magazines is that they are more prone to jamming and increase the overall weight of the weapon in which they are being used, making it harder for most to sustain accurate fire.

The M61 Vulcan is a 20 mm Hydraulically or Pneumatically driven six- barreled air-cooled The General Electric GAU-8/A Avenger is a 30 mm, hydraulically-driven seven-barrel Gatling-type rotary cannon That is, the rounds are stored nose-facing-in, and are kept under positive control by partitions running the length of the drum, and are driven forward by a helical auger. This makes their operation very reliable, even when operated at rates of fire of 6000 or more shots per minute (SPM). (In the context of Gatling-type cannon, revolutions per minute and rounds per minute would easily be confused, hence SPM)
