I've seen many people complain online about this, and it appears to be common when using dillon dies. 9mm is naturally a tapered cartridge, so some coke bottle effect is going to be a common thing. As long as it chambers and functions normally, appearence is not a huge deal.
You could be right, I only have a single stage press. It just stood out as odd to me for sure. Would that not shorten the brass??
