So there is no misunderstanding I'm not talking about .001 or .002. The variation is .018" with no error in measurement. The bullets are seated square in the jig and the measured results are confirmed using an alternate method. a (.0005" indicator and stand) and again with a 1-2" starrett micrometer. The shop is controlled at 68 degrees. I've been involved in manufacturing for over 40 years and measure accurately. I understand about the problems involved in cost and why multiple cavity dies are necessary etc.
A venier doesn't have an indicator and can easily be misread is used by someone with limited measuring experience. Generally a someone who would call a dial caliper a venier.
All the bullets weigh within .1gr
