"Brass is annealed by heating it to a certain temperature for a certain amount of time. The higher the annealing temperature, the shorter the time required to anneal. The grain structure of the brass begins to change - indicating the start of annealing - at just under 500 degrees Fahrenheit. At 600 degrees F, brass will anneal in one hour. At 800 degrees F, brass will take only a few seconds to anneal.

Only the case necks should be annealed. If the case body or head is allowed to overheat, the case will be completely and irrevocably ruined for reloading. Also, no portion of the case should ever be allowed to reach 950 degrees F. At this temperature, over-annealing will occur, rendering the brass too soft and weak to reload.

As you can see, annealing is a balancing act - the neck must be heated (but not overheated) to the appropriate temperature for the appropriate time, while ensuring that the rest of the case does not reach a temperature that will cause it to soften as well. In addition, your process needs to be very consistent from case-to-case in order to preserve accuracy."

My words: once the case is withdrawn from the heat annealing subsides. Non-ferrous metals do not require quenching to stop or complete the anneal process.



I don't buy the only the necks should be annealed statement. The shoulder needs it too.
