In this process of achieving maximum expansion of the case, I suggest doing annealing on each roll, so you can do it more quickly. I have some old 300win Lapua cases, which demanded up to 5 shots to achieve that maximum expansion. Once done, you do the shoulder setback 2 thou, and voila. Do this test Kinekilla, and you will enter paradise.shoot the brass until it gets tight to chamber . if you bump brass that is not fully expanded ,( tight to chamber ) , your over sizing the brass
