I havw a Lyman DPSII and like it a lot. I always set my RCBS 750 scale up next to it and double check every 10 drops or so per batch I am working on, There is a difference of 1/10th of a grain between the two scales at any given time. Once you get a rythm going you can move along at a good clip, I only use the Lyman when I am reloading 100 rounds or less or am working up control batches for accurracy. I then finish the load sequence on my RCBS Rockchucker, The rest of my loading is done on a Dillon 550b when I need to make large batches.
