[QUOTE="CogburnR, post: 737284, member: 29174"] If you are not lubing the necks of the case before re-sizing it will cause runout. Clean and polish the die and stem, center the stem in the die. Clean and chamfer the case mouths. Lube the case necks on the inside with a little resizing wax(or mica-graphite-moly powder) lube the outside of the case consistently. I use a Q-tip with resizing wax on it to lube necks. Every case should feel exactly the same when resized and it should not take much force to pull the case out of the die over the stem. Check the once fires to resized case shoulder length to see how far it has been pushed back. [I]If the shoulder has been pushed back too far set the die to only slightly push the shoulder back.[/I] I use a pistol case and a caliper to check this...you really only need to know if the shoulder is back a couple thousandths from a fired case(one set of dies I have pushed the shoulder back .025"). Redding makes shellholders that are made in increments of +.002" each to adjust the amount the shoulder is pushed back. If you do all the above you should start seeing runouts in the .001" range and the bad ones might be .005" if you screwed something up. [/QUOTE]
