I can't count the number of times over the years that I've had to re-do some work in progress because a digital scale went off calibration. In my experience, the biggest flaw with digital is that you never know when it's accurate. Even if you start with calibration, as the electronics warm, it drifts, sometimes substantially. And if a load cell goes quietly T.U. you can be WAY off. That's why i like beam scales. Nothing works as consistently as GRAVITY against a mechanical device. I own several Ohaus triple beam scales for gram weights, but for loading I use a Hornaday beam scale mounted in a platform with felt pads for feet. It resolves down to a couple of granules. My friend has the full feature Hornaday electronic with autotrickler, but he always backs up with an RCBS beam scale to double check, and he doesn't load for accuracy, just fun.
