My comments -
If it's getting red, its too hot. You're now past the temperature needed for annealing and the brass is too soft. Feel free to use Google and do more looking.
Or, check out these videos:
If you don't get it too hot, you don't need to put them in water. Water quenching does not stop or help anything with regard to brass annealing.
The first 25 seconds of the first video says otherwise.
Here is a couple more video's
The # 2 video he has a .3" 4 shot group at a grand. Not bad for over annealed brass.
