So, I sold some brass locally, and I broke down and ordered a Lee Auto Drum Powder Measure. It's the https://www.ebay.com/itm/NEW-LEE-Auto-Drum-Powder-Measure-90811-NIB/311497753724 with the safety lever to prevent a double-charge. I will be using it for my .380ACP and .223/5.56 loads for now(comes with 2 drums), and the auto-disk for the other loadings. I'll eventually order a drum kit and have a drum set for each load. I've read that some of the drum models are prone to leakage. Any tips/tricks for this particular model? Thanks.
