[QUOTE="oneeyejohn, post: 2072645, member: 85797"] You ask about thickness of the neck? I shoot some 30 calaber military brass and find neck thickness difference of up to .005 from one side to the other. I round the necks to between .012/.013 to get them as round as possible then Aneele and resize. This hopefully centers the neck in the case. It also makes better use of the neck bushing die without the neck expander ball. Having prepared the case this way and then using a concentricity gauge the necks are almost always under .002 out of round. I have never had a brass neck of any case brand gauge perfectly round. If the neck outside is with + or- .001 outside the inside should size the same, which means you are as close as possible to a centered bullet in the chamber. [/QUOTE]
