With brass as soon as you get it to the correct temperature it is annealed. So quenching just cools the case so annealing doesn't continue down toward the web.The Art and Science of Annealing this is a good read about annealing.Question- doesn't dropping them in water defeat the process? To harden something, you heat it, then quench it. To soften somrthing, aren't you supposed to let it cool slowly? Not criticizing, just trying to wrap my head around that cooling thing. Cases look great, tho.
