H-4350, Varget, H4895 and H-1000 weigh ~0.02 of a grain per kernal. I mostly use these powders. The finer/denser extruded powders like VV N-550, to a lesser extent RL-17 are harder to get +/- one kernel.
My scale only resolves to 0.02gr so any weights I get are within this parameter.
It took me some time to develop a technique that gave accurate results in a timely manner.
