Just resized a box for my 7mm weatherby. Annealed before resizing. Did every step meticulously. The runout on the neck on every piece of brass was between 0 and .002. Reamed the brass with a VLD reamer and seated 150gr TTSXs with a Forster ultra seater. Used a nice steady stroke and ended up with (9) at .002, (3) at .003, (4) at .004 and (4) at .005. What can I do to try and prevent this next time?
