Snork... here's definition of annealing

that indicates experience:
The once fired factory brass was thin and pinged like an empty tin can, so I annealed the case mouths. Annealing, a highly technical process based on holding a case at mid point while rotating between the fingers and heating the case mouth at the tip of a propane flame until the pain reaches your brain and you are forced to let go. The case then falls into a pan of water waiting below. If you find your fingers will not let go of the brass, you have overheated the cases.
