[QUOTE="jarnold37, post: 2419502, member: 29241"] It was stated that the softer the brass is, the more it will flow. I tend to think that soft brass is elastic and springs back, returning to size, not flowing bigger. Hard brass is less elastic and has become more brittle. Harder brass will stretch length more when resizing due to the button being pulled through the neck and the neck not able to stretch and return, non elastic. Stretch it out and it remains. Realize that any working of the brass work hardens it. Even one firing and resizing changes the characteristic of the softness, hardness of the brass. Steel gets more flexible when worked. It needs to be brought to a glowing red before quenching and hardening. Brass is just the opposite. It also needs to be glowing and quenched to soften, or to regain its elasticity. The softer brass will actually more closely "return" to its original size before "stretched." The harder brass will be stretched and will not have elasticity and will not return to original size. That is why brass becomes harder and harder to extract after several workings in many instances. I have annealed 1000's of pieces of brass and learned by trial and error that if glowing and quenched the brass will regain its elasticity' and I have never seen or experienced any piece of brass "over annealed". Have experimented with brass at temperatures recommended by some, and a button would still squeal with pulled up through necks. Glowing in a dark room and quenched leaves the brass elastic and no squeal. Have shot my best groups with new brass and brass just annealed. [/QUOTE]
