Re: Lee and RCBS powder scale inaccuracy...
A cheap scale is a cheap scale, whether it's digital or beam. As RT2506 said, that's why we have (and hopefully use) check weights. I have more issues with digital scale, as I've seen plenty of them that would hold adjustment, wouldn't weigh accurately and defied attempts to correct them. Again, they were cheap ones. Among the less expensive svales, I think the beam type tend to be more accurate and trouble free, but they all need to be checked, zeroed and rechecked from time to time.
