... Admittedly I don't do the Bench rest/Precision Shooting, and therefore don't use or need the "Competition Dies". So, my vote based on price, availability and aftermarket and Warranty, goes to RCBS. The only time I needed Warranty/Aftermarket service, was getting a part for well used, bought used, set of Dies. Very prompt and FREE replacement parts ! ..... It's nice if you can get, and use, the Carbide dies, a little cleaner an one less step to deal with. ..... 'Worth looking around for used Dies, rather than spending the extra for new,. Money saved can be better used on supplies etc. ....... David K
