[QUOTE="DUSTY NOGGIN, post: 1940396, member: 89550"] one of the causes of runout is the seating dies do not support the case body at the same time of seating .. too much neck tension results in pushing down on the case mouth on one side first . lessening the initial seating pressure via graphite , mica or pre-expanding with mandrels or neck turing to lessen the neck wall thickness.. Or combining more that one of these standardized FL sizing dies will oversize up to .008 too small on the down stroke and then pull the button through that on the upstroke (which in its self can bend the mouth axis off the case body axis ) seating into an already out of round case , doesnt give alot of chance to your end result pulling your stem out of your full length sizer to measure how much it is sizing your necks down will give alot of insight on where any runout you have is coming from [/QUOTE]
