Question on annealing?

I have been reloading a while, but have never annealed any cases.  I am a bit confused about the process.

I remember reading about filling a pan with water to part way submerge the cases.  Heating up the necks (to what point?) and then tipping them over into the water.

I thought cooling metal quickly hardens, not softens it>

Please help a newbie . Roll Eyes

Thanks,

Jerry

Annealing machine made from the innards of an old bread maker.

For me case prep is the first on my list of not so fun jobs, casting bullets is next in line.

I pre charge my center fire cases for bench shooting with the single shot, I really like to get as long a case life as possible to keep from more case prep.

Been through the annealing by hand and guessing the right temps.
Made several case holders, burnt my fingers to much before that.
Saved my pennies and bought a Ken Light annealer, Saved me bunches of r&d and trials and errors.
Very much worth each and every penny.

30-40 Krag, 38-55, 45-70 can be annealed by holding it in your fingers. A propane torch with a flame of 2" or so in length angled at 45 degrees away from your fingers. Hold the case by the base and rotate with your fingers until the end of the case glows and drop it in water. If it gets too hot to hold on to before it glows then your not holding in the correct part of the flame or your trying to heat it too much.  
Now, I'll soon have to come up with another method for 38-40s, they are probably to short to use the finger hold method.

For shorter cases I recommend that you submerge them in water up to the neck. Then lightly run the torch over the top and tip them over into the water. Do a few at a time and don’t let the water get warm. Brass is an excellent conductor of heat if you don’t stop it with water on shorter cases the body will become too soft the cases will start to stretch and eventually separate at the transition to the web.

One important point-probably made in the attached websites.  Brass anneales at 400-500 deg Fso will only be the temper colors to guide you.  The annealing temperature will occur before the blue color so stop when a clean brass neck turns straw color.  Going to a red color results in rapid grain growth esp. in a cold worked brass in need of annealing.  In highly technical metallurgicasl terms-going to red screws up the brass.  And brass does not harden by quenching-it only gets cooler.
