REALLY new to reloading.

So, how does a fixed diameter carbide die deal with the tapered 9mm cases?

I have Lee 4 piece 9mm die set, if that helps? Haven't loaded anything yet. Still trying to get the garage set up, then build a HF woodworker's bench for my presses. Loadmasters and an APP. The APP will go one one of the removeable plates, and only mounted when needed to prep brass.
