The A-Square reloading manual mentioned "annealing" the neck to prevent work-hardening the brass. The method described was heat the brass in a pan of water (about 1-2 inches deep) to prevent heating the head. After the neck is glowing knock the shell into the water. This seems to me like it would temper the brass. But it also seems like a good idea to anneal the neck because of work-hardening, like bending a paper clip till it breaks. I am wanting to know if anyone else does anneals the neck, and if so what method is used, or if this is just something that was made up (this is the only book that I have seen this in).
