That seems like quite a bit, how many cases you run. Do the cases have a burr on the mouths.

I'll see that if I'm over crimping, and if I look up in my neck sizing die. That does look like a lot but you didn't say how many cases you flared. There will always be a little.
If you haven't cleaned your dies for a long time, some of that could be from previous batches that is just falling out of the die randomly.

I get noticeably more brass shavings on my presses if the brass has been wet tumbled. If I just dry tumble the brass, almost no shavings.

Doesn’t look so bad to me at all. You know the old saying—The cleaner the brass the more the galling.
Well, this was wet tumbled. Why would that matter?

Seems normal to me for 200 cases if you were also crimping. I get a lot more than that crimping 200 fresh starline (also using Redding taper crimp)
Brass is "too clean".
That was just flaring the case mouths.
Brand spanking new brass from Starline?Not completely unusual with new cases, or trimmed but not deburred/chamfered cases. As you use them over and over, that will lesson/go away.
But I deburr/chamfer all revolver brass.

I size duburr chamfer all new brass also. I have received new brass with dented mouths burr in flash holes from lots of manufacturers. So it all gets brass prep . I also tumble in corn cob media with some polish to make sizing easier.

Can you take the expander out of the die and look at where the case mouth is stopping on the expander. If you have the standard expander it’s easy to see, if you have the TiN coated it might be harder to see.
Maybe post a picture so others can comment if it looks normal or not.
I have experienced new Starline Brass building up on the expander, and then galling the cases after it had built up. This could possibly cause shavings.

Shaving brass during the reloading process is not good.
New brass is more likely to shave than older brass if you don't deburr and chamfer...all the edges are sharp

Shaved from where and how?
Yes. They are consistent enough that I don't have to trim them, but I do chamfer/deburr them.
No, I did not. But keep in mind that this is once used brass, hence the case mouth had been flared once before using the same Redding die.

Wet tumbling is more violent on the brass than a vibratory cleaner is with the pins and cases banging against each other and it usually strips away any of the tarnish that also acts like a form of lubricant, to some degree.

I chamfer and deburr every piece of new brass, as well as any brass I trim. If I start getting shavings on my press, I will clean my dies. I also chamfer and deburr any brass that seems to have sharp edges.
Yes!

It’s just fairy dust but, yes, take the die apart and look at it just before you clean it (with what? Heck that’s another thread—but I polish with Flitz).
I’ll wager you’ll have a significant buildup on the expander. It’s a thing, but again just accumulated fairy dust.
Like was said by @JHTexas and others, and way back in post 6, too clean brass = galling.
Just for fun, take a look at this—it’s loaded.
So, your sliding soft brass into a sharp machined holder and wondering how brass gets shaved off? You've demonstrated your lack of cleaning your equipment. Important demonstration for new reloaders out there. Clean machinery lasts longer
