Hello, I'm having an issue with my lyman dps 3 ever since I got it. The problem I'm having is it despenses powder too quickly and with over throw a charge almost every time. I went on their website and they mention using a restrictor plug if this happens. My unit didn't ship with a restrictor plug. Any one know what this is or how I can make/get one. I've contacted lyman via email but have gotten no response as of yet. Any help would be appreciated.
