Early 2020, we began shipping the Auto Drum Powder Measure without a disconnector, bead chain and bell. When the Auto Drum was first introduced, it was shipped with the disconnector installed on the Auto Drum Powder Measure. Almost everybody removed the disconnector so we started shipping the Auto Drum with the optional disconnector parts in a parts bag. Almost no one installed the disconnector parts, and the ones that did, often installed the disconnector incorrectly. So in early 2020, we began shipping without the disconnector, bead chain and bell.
We recommend selecting a charge that will overflow your case if it is double charged as a safety measure.
See attached instructions for removing the disconnector
