So I'm messing around with my .25-06 and since I've added neck turning to my repertoire of skills, I thought I'd turn the necks of some Winchester brass (which actually have held up quite well) as I had never turned them. They had about 6 firings on them. I got out the ball mic and was surprised to find that they were actually very consistent at .013 all the way around. So over the course of firing, I'm thinking they just got hammered into uniformity. Is this correct or do I just have some incredibly consistent Winchester brass on my hands?
