Oh No! My Shells Won't Fit

[J.B. Books]

It is hard to tell what is wrong without a picture or two. From what you describe I am guessing there was not enough room for the volume of the shot charge and the final station crimped/crushed the top of the shell and expanded the top of it outward in all directions. ITX is expensive so you will have pry them open and salvage at least the shot. When reloading you need about 3/8 to 1/2 inch from the top of the shot to the end of the wad fingers for it to close properly. When done right the crimps should look near factory.
