[QUOTE="Mikecr, post: 448954, member: 1521"] Again, annealing reduces the stress that provides springback, and tension. 'Heat-treating' makes metal harder. This is not 'annealing', which always means to make metal softer(or stress relieved). Brass cannot be made harder by heating it--ever. Brass is always made softer by heating, and the only way brass can be made harder is to 'work' it. With softer brass(freshly annealed) there is LESS springback, and LESS tension. You typically know it's time to anneal when a few cases in a batch exhibit EXCESS tension, as seen with splitting necks or seating force variance. Annealing is then performed to normalize springback in that batch of cases, and NOT to increase tension. Your sizing/firing takes care of that. Given your annealing method described(totally wrong), and apparent lack of tension, the cause and affect is pretty clear. Cycle the brass a few times(Size/expand/fire) to regain normal springback, and stop annealing for a while. [/QUOTE]
