I use the same method as Wapati...except I use a Kerosene or Paraffin hurricane lamp with the glass chimney removed. I determine the time to hold the case in the flame as he described: Hold the case mid way and rotate and COUNT until it is too hot to hold. Then quench in a damp towel. Then hold subsequent cases at the base and COUNT to determined number, then quench. No since in burning your fingers on more than 1 case. My fingers are barely warmed holding the base. Typically on 300wm or 30-06 cases I count to 15. Anyway, its cheap, fast, simple and allows me to reload 300wm Remington Cases 10 times before the head begins to seperate note: The annealing prevented the neck from splitting.
