DIY Dedicated Case Mouth Expander Die
You can use the Lee Universal Case Expanding Die as a holder for any Dillon Powder Funnel to make a dedicated case mouth expander die. Just remove the Lee expander plugs, replace them with a powder funnel, and screw the die cap down snug. Then install in your press and adjust as you would any die.
The image at right shows the Lee die body with a Dillon .45 ACP Powder Funnel installed.

NOTE: For safety, you must drill a 1/8″ hole through the top of the cap to vent pressure in the event of an accidental primer detonation.
