[QUOTE="Buffalobob, post: 365429, member: 8"] Cases come from the factory annealed and with suitable softness and do not need to be annealed before use. After a piece of brass has been stretched and hammered by firing and sizing, it begins to work harden. After it gets to be too hard, the neck will split or the brass will no longer hold a bullet because it is too hard (exactly the same situation as being too soft from over-annealing) . When to anneal seems to depend upon the brand of brass, the rifle chamber and pressure of the loads and the settings of the dies. For extreme wildcat cartridges you may want to anneal after you have finished fireforming the case being as the shoulder and neck have been worked a lot. Generally for a 308 case I anneal about once every four firings. It probably could go longer without any problems but it is just what I do. Annealing is a time versus temperature relationship and you have to get into the correct part of the range for it to be effective. [/QUOTE]
