I absolutely hate the RCBS cheezee rings set up with the brass setscrew. They strip so easely . Sure RCBS will replace them,but with the same junk .People bitch about the Lee system, but I find that they holdrather well. I like the Hornady rings the best with Lee second and RCBS dead last. One thing I have done before I got any Lee dies (I had only RCBS dies at that time) is I went to the hardware store and bought brass screws as one can reef them down without striping unlike the setscrews. You have to dremel the the screw's head a tad so the screw head does not catch on the press body. YMMV
