It's as simple as that. I've got 2 Chinese 75rnd drums, one lightly used and the other still sealed in the package. I've also got a Romanian 75rnd drum that I snagged at a gun show for $50 out the door. I plan on trying to get some more Chinese 75rnders or maybe some of the new Bulgarian 75rnders. I would like to have about 10 or so just for the hell of it. I like the backloaders because I don't have to wear myself loading it.
