PURPOSE: A drum-type magazine is provided to increase the tensile strength of a tension member by using a tension regulating unit when the tensile strength of the tension member degrades by repetitive loading of bullets, thereby stably maintaining a loaded state for bullets. CONSTITUTION: A drum-type magazine(100) comprises a drum unit(110), a plurality of dummy bullets(120), a bullet guiding unit(130), a tension member(140), a tension regulating unit(150), and a bullet loading unit(160). Bullets are loaded into a space with a helical shape in the drum unit. The plurality of dummy bullets is embedded in the drum unit. The bullet guiding unit is joined to the drum unit and guides the loading of the bullets while rotating the tension regulating unit. The tension member is mounted in an outer side of the drum unit and elastically supports the bullet guiding unit. The tension regulating unit regulates the tension strength of the tension member. The bullet loading unit rotates the tension regulating unit by operating a loading lever, thereby loading the bullets into the inside of the drum unit.
