Why is military ammo annealed?
When brass is bent, hammered, or shaped, it becomes harder and more brittle. This is what happens to a cartridge case when the neck is formed. The annealing process restores the ductility of the case by reducing internal stresses in the brass, making it easier to stretch under pressure rather than crack.
