Rings from seating bullets

Ladies and gentlemen I come to you once again. After seating my 9mm bullets im finding rings around where the end of the bullet should be. Some of which can even be felt. Im using an RCBS 9mm carbide set, and even after experimenting with how much flare to apply im still getting these rings. My question is what am I doing wrong? Or are these rings normal? The bullets are centered as if they sat properly but it seems like they're expanding the case as they go down. (Ignore different OALs those are the experimented shells with no powder to be pulled for the bullet later)20201007_142054.jpg
Edit: I've already disassembled them but would it come out in the taper crimp?

Looks like typical handgun Ammo to me. Mine has always functioned when it looks that way. A carbide die sizes the entire case to the same diameter. From the factory there is a slight taper. Shove a straight bullet in a sized case and it shows where it has expanded to fit.
 
Thanks all, I guess that is what I get for being too paranoid. I should have just called it good when they still passed the plunk test....

That's typical of a straight walled case. What would concern me is why different seating depths? Are you not letting the ram go all the way up? or are you testing

Twas a test, I was seeing if it was a few potentially bad shells or a regular issue.... of course what I know now it wasn't even a problem. New reloaders with dumb questions I guess haha

It's only dumb if you don't ask. I started reloading 10 years ago and am still a newbie.

a miss matched seater stem can and does cause bullet to bulge to one side of case it needs to match profile of bullet nose as close as possible guiding in strait, I've experienced this one sided case bulge slow down your speed seating bullet, just my experience.

What weight bullet is that? I am guessing the this is mixed headstamp brass.
