[QUOTE="kiwikid, post: 1876184, member: 56094"] Have you measured the neck diameter of your fired cases? If it is more that .004-.005" larger than your sized cases Redding suggest sizing in more than one step. For example I have a 6.5x55mm here that the fired RWS brass measures 0.299", loaded rounds measure 0.293" so with my desired .002" of neck tension my sizing bushing is 0.291". Sizing from .299" straight to .291" was producing around .002"-.003" of neck run-out, by first using a 0.295" bushing and then the 0.291" bushing my run-out reduced to .001" or less. This is also with a Foster Co-Ax press and Redding Competition Dies. [/QUOTE]
