I have been doing a lot of research looking at different automatic powder scales/droppers. I have seen a lot of people recommend the Intellidropper, but a friend tried one and it was off a ton. It was always over by 1.x grains almost all of the time. He calibrated it multiple times. So I am not sure if it was just a bad unit or if they are not that great. I looked at the Chargemaster and some of the others. They all seem to suffer from similar issues. So that lead me to the Autotrickler. I am fine with buying it if that is one of the only ways to go. I am looking for input from people that have tested a lot of the different systems.
