You may laugh at my method but here it is: First do this in absolute darkness except for a small neon nightlight. Do it in the night time. Wait until your eyes are fully accustomed to the darkness takes about five minutes. Create a propane torch light so that the inner blue is roughly half or three quarters of an inch, rotate the Shell in a socket connected to an electric screwdriver, bring it to the tip of the inner flame on the middle of the neck until you can just absolutely barely see a color change to dark dark dark red. Try to make each shell be in the exact same part of the flame for the exact same time, to the exact same dark red, drop in water.
I forgot to say to Decap before you do all this.
Shake out the water as best you can, put them in some suitable container and dry either in sunlight or in an oven at no more than 180°F for about 30 minutes.
There is a good chance that you will have slightly over annealed the brass. I have shown some increase in the consistency if I then run them in and out of a full length sizer expander ball three times. After lubing them of course!
Of course you can always buy a wonderfully good machine for about $500 that will probably get better results, I just don't want to spend that much on it.
