Eliminates the need for case lubrication and cases do not need to be cleaned before sizing. Set consists of a Carbide Sizer Die with Decapping Unit Expander Die for expanding and belling the case mouth and a Seater Die with Roll or Taper Crimp and Bullet Seater Plug.
Works great as expected, been reloading for 25 years and have tried a few other brands but RCBS keeps me coming back. Never had a need to load for 9mm until this “pandemic”. Now to try and score more small pistol primers.
