I have an RCBS beam type scale and a Redding beam type scale. I purchased the Redding because I was so impressed with the Big Boss press that I thought I would try it. It is easier to adjust then the RCBS and I like the vertical tenth scale, the RCBS does not have that feature. The Redding scale is a bit harder to read and both scales settle out about the same. The RCBS has a dished pan and the Redding is flat. However, they are both dead accurate. Each pan has a 20 gram calibration weight and it does not matter where the weights are sitting in the pans. They still read 308.6gr. I am always amazed at how accurate they are.
