I agree with Texas10. The problem with digital scales is that you never know when they are accurate. I have a GemPro 250 which I like very much. However, I wasn't pleased with the SD's and ES's I was seeing with the chrono. I did several test comparing the GemPro to my RCBS balance beam. Much to my surprise, I found that I got consistently tighter groups with smaller SD's and ES's with the balance beam scale. I still used the GemPro to weigh bullets and cases, but rely on the balance beam scales for powder.
