Bart is correct. I get amused by those agonzing over scales that "only" weigh to .1 grain; some guys spend hundreds for super scales to get "better" accuracy! It's clear they haven't considered that uncontrollable/undetectable differences in cases, primers, powder lots, which way the ducks are flying, etc, have as much or more impact on accuracy than .1 gr. of powder in a well developed and assembled reload.
The value and speed of digital powder dumpsters is directly determined by how good or poor our skills and work methods are; the worse we are, the better the auto-gadgets become.
