I got the dies fixed, removed the rust, made a new headed primer punch, straightened the threaded part.
I chucked the expander and cut the bottom of the die smooth. I went to remove the seat punch nut and could hardly budge it, Got it off and found plier marks on the threads, trip through a die fixed that.
The more I think about it the more I think he ran the expander into a .41 case.
