I recommend you send the ones you've loaded, record performance and case dimensions. To unload and anneal requires removal of unfired primers, which is I'll advised in addition to potentially inflicting damage to loaded bullets, which will introduce an unmeasurable variable into rounds in which they are incorporated, IMO.
I have read and re-read the posts here. Not sure what some are saying. BUT do not anneal brass with live primers. You will be flurting with a possible disaster.
Only annealy brass with expended primers or no primers.
