Success at last. I turned the die upside down and put it in the press like suggested. I didn't have a tap so I used a self tapping screw and screwed it into the base of the casing and with a washer under it started tightening it andthe casingpopped loose. Thanks for all the excellent replies and information. I put the die back in the press and lubed some cases and resized them and they look good. No scratches or other deformation so I assume the die is okay. Again thanks for the help.
