Drum beat! Performance tips!

Wanted to share an issue that I caused with my drum to save anybody else the trouble of learning the hard way.

Before I even attempted to load the drum I tore it down as per the instructions manual.

While reassembling I apparently over tightened the small screw at the base of the mag tube.
Went to the range with 25 rounds in the drum, the first 18 or so shot fine.
Then as the follower was starting to enter the mag tube it locked up.

Once I was home I was able to back the screw off a tad and the mag feeds all 32 rounds on a bench test X2.

Also I was able to feel the bind when loading. Based off my extremely limited experience, if the rounds are hard going in they will not be properly fed out.

So to summarize, don't over tighten the small screw at the base of the mag tube.
