50 round drum malfunction

[Bat 2919]

I know two shooters who use the Drum exclusively in AZSA matches.  These are their thoughts on possible problems that may cause malfunctions:

Being wound incorrectly.

A dent in the drum.

A defect in the pinwheel.

I also know that they both wind the drum springs more than what Auto Ordnance recommends and claim they have better luck with them that way.

I've been giving it 9 clicks, guess I'll try 11. The round doesn't go sideways as long as there is another one beside it.

There might something to be said about how tight you wind the drum. I tried shooting with the drum full with 50 rounds. I wound it according to auto ordinance instructions. First 25 rounds went off with out a hiccup! The 26 round jammed. The spring felt like it was unwound. I wound it up about 15 times and the rest shot with out a problem. The drum is cool looking, but I see where it can be a pain in any kind of serious shooting.
