Color me stumped. I am reloading .308 Lapua brass with both Barnes and Hammer bullets. Brass was prepped with a Redding body die, and necks were sized using a Lee neck sizing die. I checked my brass after those steps and runout is basically nonexistent. I am then using a Forster Micro-seating die, and I am getting runout that fluctuates between essentially zero, to some that approach .007. I'm seating them carefully. I've tried seating part-way, turning the cartridge, and then seating the remainder of the way. The runout seems pretty random to me, as there are loads that are perfect. Any thoughts?
