Re: powder measure ????
I have the older RCBS (PACT) system where the scale is separate from the dispenser, so I can't speak to the Lyman 1200.
My RCBS has been a good unit. The only difficulty I've had is when I try to cycle the press while the unit is measuring, bench vibration will affect the accuracy.
As far as finding a mechanical measure that will be accurate enough no trickling is required, I think that's going to be pretty tough to do.
Hope this helps
