For troubleshooting, maybe you can try pulling some factory bullets and loading those into your rounds. If they feel tighter, then your bullets are most likely out of spec. If they feel the same or looser, then it's probably your brass being loose from the resizer or expander.
Also, you can try using a set of calipers to measure the bullet instead of a micrometer. If it's too small, it'll be noticeable in the measurement. It's not like we're looking for exact numbers here.
If you do end up getting new dies, I recommend RCBS or Lee for the best bang for buck.

Re: Nosediving 9mm Handloads, Crimp Issue
What's the OAL of your rounds? If it's too long, it may nosedive.
Also, what dies are you using? And brass? If you can put the bullet inside the case without using the expander die, then the resizing die is not doing its job or you have bad brass. Or maybe undersized bullets. What bullets are you using? What is the actual measured (not claimed) diameter of the bullets?
