Rick,
A tuned beam scale zeroed to an average primer weight should be able to detect primers that are 1 or 2 kernels of Varget heavier or lighter just by looking at the pointer/scale.
Even a cheap digital with just a milligram resolution (about one kernel), and care watching for drift could do it.
The milligram FX120 should be good enough and faster.
Getting weight bins to 0.02grains would take extra effort though.
At the minimum, go for finding outliers.
