One decent full length sizing die is all one needs to size fired cases. Use one that has bushings to make the neck size just right, decaps cases, doesn't have a neck-bending expander ball and you'll get the best accuracy and case life possible. That's what Sierra Bullets does and I doubt anyone shoots their stuff more accurate than they do.
