As of early 2020, we are shipping the Auto Drum Powder Measure without a Disconnector and Chain. 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. Then, we started shipping the Auto Drum with the optional Disconnector parts in a parts bag. Almost no one installed the parts, and the ones that did often installed them
incorrectly. We recommend using a charge that will overflow your case if it is double charged as a safety measure.
See installation instructions if you have a legacy tool.
