Buddy of mine mounted a single stage upside down for bullet sizing. He said this way he doesn't have to guide the bullet upward into the die. He just drops the bullet in the die and pulls the handle. I'll see if I can get a picture.

I don't know why. My buddy and I are constantly cookin up some wild idea. This is one of the few that came to fruition.
