I like my old Lee priming tool better than the RCBS. Changing base sizes is a PIA with the RCBS priming tool, IMHO. I bought my RCBS priming tool because the old Lee would not handle the large base of the Rigby. It is set up for one cartridge and will stay that way.
Have you seen the new Hornsby one that looks like the old LEE?
I was wondering if the bought the design and if the parts are interchangeable.
