[QUOTE="Trickymissfit, post: 987670, member: 25383"] unless you want to anneal the case body as well as the neck and shoulder, you must shock the brass to stop the heat transfer from the neck area. Shocking the brass is nothing but a rapid quench process. The quicker you quench, the quicker the heat transfer stops. But even quenching in ice water will not stop the transfer 100% contrary to popular belief. The warmer the quench medium, the more heat is transferred. So speed is the priority here. I'd recommend a trip to the public library for a quick read on the subject of annealing brass. You'll soon find that most folks over heat the brass right from the start. Four hundred to five hundred fifty degrees is about the perfect window. I like the 430 degree area best, and by the time I quench the brass will be about 470 degrees. I use welder's temp sticks to be certain Too soft of a case head can be dangerous, and really all you worry about is the neck and shoulder. gary [/QUOTE]
