I have several of the Redding Type S bushing dies. I dont think they result in more concentric necks but the ability to adjust neck tension can sometimes make a difference in accuracy. I've been using Forster dies for years and still do and they're very good.

For most of my rifles I'm sizing without an expander ball and using an expander mandrel die in a separate step for more consistent neck tension.
