Heavy Weapons
The drums of aircraft cannons such as the M61 Vulcan and GAU-8 Avenger resemble drum magazines for small arms, but function in a different manner. 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 an externally powered helical auger. This makes their operation very reliable, even when operated at rates of fire of several thousand rounds per minute.
