Having just spent most of New Years Eve and this morning loading/charging cases with my Gempro 250 I have to add:
I loaded years ago with my RCBS beam scale and it was top notch and accurate. I still have it. Nothing wrong with the tried and true beam scale. I returned to shooting/loading 30 years later and started with my beam scale and bought a digital and a brand new set of check weights and loaded and compared the two side by side when loading .32 acp where +/- .10 is just not close enough. When checking the charged cases side by side for .02 gr. accuracy the digital beats the beam hands down. If you only need .1 gr. accuracy and use ball powders then a beam is way fine. I frequently charge 50 cases and then randomly dump one after the other onto the scale after a finicky check with check weights all around the weight I am weighing.
If you are using a flake powder (I use Unique exclusively) and are loading small calibers at the upper end of pressure and accuracy and hand weigh *every* charge the digital shines in speed and accuracy so far beyond the beam it is not even a close race for me. So, it depends on what you want and what calibers you load and what powders you use. Different demands will demand different equipment - we all use/should use what works best for us in our situation.
That added: without a check weight set and without using it to check/verify linearity and accuracy yer just guessing and hoping the scale has not changed calibration on you. Beams? Not likely if you haven't dropped it or let it get abused. Digitals? If they change calibration (and they can go bad....) and you have not verified that yer check weight set reads 2 gr. when it's a 2 gr. weight and 20 when it's a 20 gr. weight, how would you know it's off?
I trust my digital but verify the accuracy with check weights before, during, and after charging cases.
