I cut the female end off a short 1/4" extension which allows me to change sockets for different calibers. I have used this method to form .224 K-Chuk brass from 22 Hornet and .256 Win Mag brass from 22 Jet. Also did a few 7mm TCU from 223 brass. All of the different brass used a different socket, and the short extension kept the drill chuck farther away from the flame. I did not quench the brass after the annealing, just dropped them into a metal pie pan to cool.
