"set them in a pan of water up to the shoulder of the case with the mouth pointing up, heat with a torch until red hot, knock them over in to the water to anneal them."

I might add to DA's comment that the room should be darkened a little so as to notice the red brass sooner. Like anything, the heat can be "OVER" applied.

Friend of mine just rolls the brass in his fingers, held by the head in the flame until it is a little too warm to hold then quenches. But then his brass is mostly .30/06 or 7.65 Argentine. Shorter Bee brass may not work that way. Your call.
