[QUOTE="Bart B, post: 116725, member: 5302"] I get the least bullet runout when cases are full length sized in dies having their necks lapped out about .002-inch smaller than loaded round neck diameter. This sizes the fired case neck only down and the neck isn't bent when the case is pulled out of the die cause there's no expander ball. Bullets tend to align themselves to the neck axis when seated. Cases so sized as above can have bullets seated with just about anything and get runouts less than .002-inch. Depending on how the runout measuring tool is set up, one can get a .002-inch spread across them. There is no industry standard in bullet runout measuring tools. If bullets are seated out to touch the lands when chambered, even .003 or .004 inch runout rounds will shoot very well indeed. [/QUOTE]
