[QUOTE="jarnold37, post: 2562709, member: 29241"] Some brass is needing annealed when new. I had a heavy barreled sleeved rifle built by one of the top rifle shops some years back and being an Ackley improved I started fireforming. 50% of the new cases split when fireforming. Sent back to gunsmith and was told chamber was correct and the problem was I had brass that needed annealed. A major brass manufacturer engineer instructed me to heat with a propane torch until glowing orange and quench in water. It is brought to a consistent state by the quench, not the initial heat. But initial heat needed to be a glowing orange in a dark room to insure soft enough. If not brought to a soft enough state brass will still be too brittle when quenched. Experimented by pulling button up through neck after increasing temps up to orange. Only when orange did the button not squeak and have correct elasticity. Hundreds of cases been annealed and have never experienced 'over annealing' or damaged brass. I think many annealers are not getting their brass elastic enough. In some cases one firing and resize hardens brass to the point of innacuracy and flyers. [/QUOTE]
