Re: Dumb question about RCBS powder measure...
If you are checking your load into the scale pan, put the pan up against the bottom of the drop tube, cycle your handle, and then slowly lower the pan to allow it to fill slowly. Once you have your load checked, then put the case mouth into the bottom of your drop tube and cycle the measurer. Powder will drop into the case with no spillage. Also, watch how fast you cycle your handle. Go slowly to allow an even drop. Shouldn't have powder spill out on the upstroke. Is it coming out of the reserve?
