Gotta get a scale. Should have this already.
I have a number of dippers for pet loads made from trimmed 9mm cases.
Always calibrated. Only re-calibrate with new lot of powder.
Never go out of adjustment.
First charge just as accurate as the last charge.
EASILY HOLD +/- 0.1 grain all day long. Even if using a Harrell measure you better use a scale on each charge if you need better repeatability.
All the Best,
