I have a rcbs powder measure that I use to throw my loads then trickle until I get them where I want them. When I work the handle on the measure all the powder will not fall out until I move the drum from side to side a couple times. I am calling the drum the piece that the handle fastens to. I can push it all the way to one side then back to the other side and a little more powder will fall out. It works good and throws consistent loads as long as I remember to push it from side to side each time. Anybody else had this problem?
