[QUOTE="3sixbits, post: 61020, member: 3661"] Yes sir, The neck being thicker in one spot is really telling you that the rest of the case has a thicker area the full run of its length. Try this when you find a case thats out in the neck, cut the case length wise and use a ball mic to measure the case walls. In some of my barrels I shoot fitted necks, with the bullet seated I want a clearence of .001 for a total. thats .0005 on the sides. The reason I want this type of fit in these barrels is the chambers have under size necks and this fit gets them as close as possible to the center of the bore. Before I cut these neck I spin the cases and only select necks with vary small amout of TIR. These barrels are not hunting barrels but match barrels.
