I think I'd stick with a beam scale for weighing charges since you just zero it, set it for the weight you want, and everything else is realtime and analog, which is more accurate than most of the digital powder scales which are good only to +/- 0.1gr. For my 22-250 I'm shooting for less than +/- 0.05gr, and I'm fairly certain I get repeatable accuracy down to probably +/- 0.02gr.

That doesn't mean that I'm not going to get a digital scale ASAP. Not for weighing charges, but for weighing everything else like cases and bullets. A digital is ten times faster for weighing things that have variable and uncontrolled weights.
