[QUOTE="Greyfox, post: 1737596, member: 10291"] I don’t think anyone is questioning the concept of annealing. Many do question whether it’s “always” required to produce precision results. Being an alloy, and subject to variations in formulation, all brass is not created equal. Particularly between rifle brass suppliers. The variations in composition results in differences in hardness, tensile strength, resistance to work hardening, coloration, and other physical properties. Compare the various brands of brass, and these differences can be observed. There are also differences in wall thickness from brand to brand. Add to that, the varying degrees of sizing(working) the brass due to variations in chamber and dye dimensions, and it becomes quite evident that the need or frequency of annealing is not a constant. IMO, the way to determine annealing requirements, is the use performance and results as a guideline. My 6.5x47 using Lapua brass can hold low ES and accuracy for 20+ reloads without annealing. This rifle has tight tolerances. I get 3 firings with my 300WM using Winchester brass before needing to anneal. The combination of thin brass and a generous chamber neck works the brass excessively when sizing. IMO, annealing brass is not a fait accompli. [/QUOTE]
