Will bushing dies eliminate doughnuts? Particularly because of how much of the neck they do or do not size?
One well-known benchrest competitor claims bushing dies tend to encourage doughnuts, though in the article I read he didn't explain why.
That has not been my experience. In fact the dies for my own 6mm PPC benchrest rifle are Redding Competition, and I haven't detected any hint of a doughnut in the brass since starting to use it years ago. But then I don't shoot in matches. Instead I acquired the rifle to test what factors affect accuracy.
