I bought a RCBS 750 Digital scale yesterday because I also comes with check weights. Most of the reviews I read were good or in favor of this scale too. So I calibrated it and zeroed it too. I warmed it up also as I read some say to do with digital scales. I checked it along with my new Dillon beam scale and they are right on. Even the penny of 46gn that was sent to me was right on. So now I think I have a winner.
