If its a large flake powder, just watch your consistency when using lighter loads (less then 4gr). Large flake powder and light loads from the Pro, make for a good chance of "bridging" and a squib. They do work fine in the regular auto disk.
If its ball powder it should be fine, even small flake like Bullseye or Power Pistol are ok, JUST large flake like Clays or Unique are problematic.
