Brass dust on full length sizing die?

[Alchemist]

Hi all,

New reloader. Started sizing my tumbled/cleaned .223 deprimed cases yesterday. I used a lube pad to roll the cases across and a brush to lube inside the neck. Saw some brass “dust” on a lot of the shells after removing from the press, most evident right on the mouth of the case. It’s not shavings and it’s very very light but I don’t think it should be there should it? I’m using a Lee single stage breech lock press, Lee dies, RCBS lube and lube pad.

I’m following instructions and haven’t lubed the outside of the neck or the shoulder. Should I?

Dismantle the die and clean it? Anything I can do if I find rough edges?

Why would you not lube the outside of the case neck?

Thought the instructions of the RCBS lube kit said not to. Perhaps I misread something. Is it just the shoulder that shouldn’t be lubed?

Edit. Looks like user error (me). I’ll add a bit of lube to the case neck outer and see if I get less/no dust.
