So my .223 brass finally started to split after 5 loads. I did some research on annealing and went out and bought a pencil torch. I've been spinning the case with a drill/socket setup and then quenching in a bowl of water. My concern is over heating the brass to the point where it becomes too weak. How do you guys judge when to stop heating it? How dangerous is it to over anneal a case? I read it can be really bad. ETA: I know you want a blue color, and NOT for it to turn red hot. Beyond that I am lost. Wanna kill these ads? We can help!
