Then size with the case-neck expander and rechamber.
Then seat a bullet and re-chamber.
Separating all the individual metalworking steps like this will let you know exactly which one produces the problem.

What do you find when you try to chamber the case at each of these four points in the time-line of reloading?
About your picture, that third round with what appears to be a belt around the base of the cartridge just looks wrong. My reading of your first post did not appreciate the degree of the problem. I don't know what is happening there, but it ain't right. First thought is that the die is not adjusted correctly or the case is not entering the die fully (but your first post specified the die was contacting the shell holder, so that can't be it).
I'm just puzzled.
