FYI: I've recnetly tested (and bought) one of the Ohaus Navigator scales that have a .05 grain resolution (492.00, 492.05, 493.00) with many other options on it for grams, grains, rezeroing for comparison measuring, etc,etc,etc. The price is steeper (usually $400+ as mentioned in an earlier post) than the digit scales put out by the major manufacturers, but the resolution is much better and it's repeatable with my check weight (after warming up as was already mentioned) They are available from Clinch River Outfitters
. They have another higher model than the Navigator that has a resolution that goes down to .02 gr but it was to pricy for me.
For comparison measuring of cases/bullets in a short amount of time this is unbeatable. But like anything you have to determine if the price warrants the real need for the speed and resolution it gives. For someone measuring powder to reload it's probably to much. For a competition shooter or someone who wieghs a large number of items to do statisical control with, it's a very large time saver.
