I know this is an old thread but I ran across a guy from Canada that makes a powder trickler that interfaces with a A&D FX-120I scale and the Sartorius/Entris scale. He sells the FX electronics and trickler for $199 (not sure if US$ or Can$) and the Sartorius version for $249 so if you have one of those nice scales, this would get you auto trickling to the single Kernel of powder (depending on powder).
There is also a long thread on the device at http://forum.accurateshooter.com/threads/turn-your-fx-120i-into-a-prometheus.3897203/
This set up really appeals to me since my Gempro 250 wanders a bit.
I will make a new post on this later.
Happy shooting all.
