I've sold Lee,Redding, and Hornady dies in the 500S&W. The carbide ring in the sizer, on the Lee's, broke on a couple. My customers sent them back, and Lee always makes it right. Never had any complaints with the Redding or the Hornady. Talked a couple of guys into just buying the standard dies, instead of the carbide. After talking it over, they figured they were only going to load 300 or 400 rounds a year, so will just lube that many, and not worry about the ring breaking. gypsyman
