[quote=Mule Deer]An "un-sized" portion of the rear of the neck is not necessarily a doughnut.

If you use a conventional FL sizing die afterwards without the expander it can force the midriff bulge to the interior and form a doughnut. Some like the bulge as they think it helps to center the case in the chamber, not sure about this one though. I only turn necks if forced to and then my cutters have the bevel on them.
