Hi,
Never tried the dryer sheet trick--but I have run a ground wire from shotshell machines to a grounded screw on a wall plug to help, though. Those machines are mostly metal, as is the Uniflo on the bench. Dunno if this trick would work w/ a mostly plastic measure, like the Lee "Perfect" measure next to the Uniflo.
Lee suggests, w/ their dippers, to wash 'em w/ dish soap and water, then let dry WITHOUT rinsing. That trick has worked for me. I s'pose one could wipe out the plastic hopper of their measure, or wash the plastic disks, w/ a soapy rag (not TOO wet--don't want water running down into the innards!) and see what happens?
