I had to cut the shell in half to remove. I did tighten the rod in the collet using two adjustable wrenches. Very leary to using this die again. Do you have a solution to correct this. Thank You.

The first just yields the neck down but does not squeeze it tight. You can feel the neck give. Rotate a bit and squeeze to full pressure (don’t need a lot). Rotate a bit more and squeeze to full pressure again. It is relatively quick and comes out straight and round as measured on the concentricity gage.
