There are some write-ups on the method on this Forum. It's a matter of obtaining the proper duration of application of the heat, which is dependent on the temperature of the torch flame. Gotta get the case neck shoulder joint up to around 650F quickly, without allowing the case head to ever get heated up. Also, if you overcook the case neck the brass case can be ruined.
There too much to write up on my method to take the time at this moment, but I basically spin the cartridge case in a battery powered drill, holding the case head in a Lee case head holder chucked into the drill. I use a 3/4" long focused blue propane torch length. Spin the casing while holding the case neck/shoulder joint at the tip of the darker blue flame for 5 1/2 seconds. Quickly remove the casing from the flame tip and drop the case into a container of cold water. I keep a large clock with a second hand visible behind the torch flame so I can watch the second hand while spinning the case neck in the flame.
Research the subject and practice on some reject brass before launching into your good brass. You'll have to devote at least one hour to researching the subject before you'll be prepared to begin annealing. That was my experience. You'll find articles on the topic if you run a Google search.
