MD, I have brought a few back to normal by simply running the case necks back and forth into the neck portion of the sizing die and back over the neck and expander ball without removing the case from the die. At least that seems to work.

Have you ever tried that? Five or six cycles, and the necks are back to where they should be.

G'day. How can you tell if brass is over annealed? Thanks.


I tested the ones I saw by pressing the neck mouth with my thumbnail, and they dented easily. Five or six runs back and forth as stated above and they were firm again.

Work hardening via sizing/expanding. That's how new cases become harder (less plastic) during firing cycles, therefore annealing is required to return the case to an acceptable condition.


Exactly, and that’s also how you can restore necks that have become too soft from being heated too hot.
