I stand corrected, it is indeed the working and stretching going on. Trying to say a lot and got myself turned around.

And no have not tried Templec in that application. Obviously it does not correct the brass with the created heat ergo need to anneal. Speculation as to why, heat sink in contact with the chamber may preclude that.

As too much heat just softens it permanently the flip could also happen but does not.
