[QUOTE="Steve Sheasly, post: 1711281, member: 103826"] This is correct and I confirmed by talking to Nosler. I knew it had to be annealed because of cold working. Unlike steel alloys, brass cannot be hardened by heating. Brass can only be strain or work hardened. This hardening occurs when the material is worked mechanically, e.g. by cold working. ... If cold worked brass is heated to 450 – 600°C, the hardening can be removed again and this is why we have to anneal again. Fire forming is cold working and so is putting brass in a die. This is also why I neck size then full size -- and repeat. I have worked with many foundries in my engineering career. Which now is over and I can shoot all I want --- unless I run out of money!
