I just loaded my 110-round GSG drum for the first time. It says right on the back of it not to use waxed ammunition, so I filled it with Stingers. I saw somewhere online that said it would hold 118 rounds, but it won't work if you put that many in it, so you need to count the rounds as you load it. CCI boxes you can dump 5 at a time from makes that easier. I tried seeing if it held more than 110 rounds and it took 118 just like that person said. Then I took the 8 extra rounds out and put them back in the box. One of these days years I need to see if this thing works. Someone on YouTube said you can leave it loaded indefinitely, so I'm leaving it loaded. It's a pain in the but to load 110 rounds, one at a time, and when it's time to shoot I don't want to waste any more time.
