I have been buying Redding dies, exclusively, for the past few years. I really like them, and in some cases they are cheaper than RCBS. I have die inventory that's about 50/50, Redding vs. RCBS. I also have a set of Dillon .45 ACP dies, and a set of Lee .454 Casull dies. I won't buy Lee again, except for their factory crimp dies.
