An ammunition magazine for a gun includes a magazine body and a follower. The magazine body defines an interior space in which a plurality of cartridges is receivable. The magazine body includes a drum portion and a tower portion. The drum portion defines a drum axis. The tower portion has an upper end with at least one feed lip thereon. The follower is received in the interior space and configured to bias cartridges received in the interior space from the drum portion up through the tower portion toward the at least one feed lip. An angle of the follower relative to the drum axis changes as the follower moves from the drum portion to the tower portion.
