The perfect powder measure is an adjustable drum type dispenser. So instead of a fixed disk you have a cylinder to adjust. In my experience with exactly one example of the auto disk and perfect powder measure the PPM has tighter tolerances, but I've never used a flake powder (or any of the VV powders you are using).

I normally get +/- .1 grain accuracy with the PPM, and that is using ball or stick powder. I recommend it, and even if you get a +/- .2 gr accuracy, then you still have less work to do with the powder trickler.
