I'd bet you your dies are not scratched.Now, all my 223 brass has deep scratches covering 99.9% of the necks!
Take a dowel rod, split the end with a thin saw, and insert a double-flap of 600 grit Wet or Dry emery paper.
Then chuck the dowel in a drill and polish the die to get the galled brass out.
You will not hurt the die or make it larger, unless you spend several hours doing it!
Removing the galded brass stuck on the surface will only take a minute.

Trying to get that Pre '64 look?I'm old old school and use a rag to clean my hulls and very sparingly at that.
Now you're talking, I found out years ago that a shiny stress crack is easier found on unpolished brass; that's my excuse and I'm sticking to it.Trying to get that Pre '64 look?
