Something is wrong with that.
Anyway, unless you are going to do that over and over and over, 005 to .008 isn't something to worry about.
Neck tension is what holds bullets in 9MM, not the taper "crimp" that should only remove the bell or a hair more, maybe .001) The reason is that the 9MM headspaces on the case mouth, as well as too much crimp can actually hurt neck tension, even if the over crimp pushes the case into the bullet, stopping it from moving back. That's hurts the consistency of the burn. It is important to have the 9MM sizer all the way down since the case is tapered, and for the expander not to be too big.
