Drum magazine

A drum magazine is a type of high-capacity magazine for firearms.^[1] Cylindrical in shape (similar to a drum), drum magazines store rounds in a spiral around the center of the magazine, facing the direction of the barrel. Drum magazines are contrasted with more common box-type magazines, which have a lower capacity and store rounds flat.^[1] The capacity of drum magazines varies, but is generally between 50 and 100 rounds.^[1]
