For what it's worth, I cobbled up a quick video of how I load my GSG drum - just in case some of the earlier posters may have been missing some detail or another. The descriptions I have read here sound pretty much the same - it's a matter of finding the balance between pushing the rounds down, and advancing the disc.
Better that, than a defective unit.
I love mine...far more than any of my three aa922s, none of which can be emptied without a failure.
Cheers
