Guys- when annealing indoors, always turn the lights out - anneal in a darkened room. I hold the case by the head, in my fingers and rotate the case neck in the flame of a MAPP Gas torch on a propane bottle. The temp is enough higher than a normal propane torch to be quite useable. When the necks start to turn dull reddish (cannot be seen in a lighted room), drop them into a bucket or container of water. Done. Take them out when finished, roll them out of a cloth towel and sit them in the sun or put them on a cookie sheet in the over at 170 degrees for 30 minutes or so, to dry.
Been annealing brass since 1968. Been annealing brass as above since I joined Saubier.com small bore forum and learned to do it this way. It's the best and NEVER get an over-annealed case now, which did happen if annealing in a lighted room.
