I took the depriming mandrel out of the resizing die and got them resized just fine. I think my mistake was not paying attention to the instructions which said to turn the die in till it touches the shell holder, then turn one full turn more... 1 ½ turns for the Classic Press. I have the Classic Press and only gave the die one turn. Did 1 ½ turns today, and they resized and took the bullets just fine. Learning steps.
