hey so ive been using Unique cause i have a whole lot of it. works fine, just dirty and doesnt meter real well. the dirty isnt a big deal to me. Ive got a RadioShack 3v mobile-phone vibrate motor attached to my powder measure. The motor improves the consistency of the throws, but they are still only +/- .1grain. Tapping the hopper before each throw gets down to (i would guess) +/- .05grain. I think another motor in a different axis, or a larger motor would work better . . . Anyways, what powder do you guys use that meters close to the consistent accuracy of trickling each charge into a balance beam scale?
