I'm going to suggest that he uses a tight chamber and has straightline dies matched explicitly to the chamber.
With the minimal brass working that comes from the close match of dies and chamber he will get very long brass life. This is why benchresters are able to run the 6mm PPC case well past the design pressure and still have 8 to 10 firings per case before the case starts to let go of primers.
