[QUOTE="VarmintBob, post: 2897765, member: 124886"] metals have a property called "modulus of elasticity". For brass, every time you fire (stretch) it and then resize it you have changed that parameter. Your bras that will not "push back at the shoulder" has a higher modulus of elasticity from being worked. The only way you can change that parameter back to a level where you can get the shoulders to not spring back is to anneal. The reason for annealing is to reset the modulus of elasticity to as close to the same value as you can get for each piece of brass. Otherwise, you will see what you have now. The other thing to do is check inside the case at the base of the neck for donuts. [/QUOTE]
