[QUOTE="barefooter56, post: 1015286, member: 85389"] merbeau, If I am reading this right that your measurement across the mid-point of the neck on a loaded round is .276 and the measurement across a sized neck is .269. You are putting about .007 neck tension on that bullet. That's a lot. For a hunting round we usually recommend about .003-.005 neck tension. A few ways you can relieve the neck tension from a loaded round when you are using a standard full length or neck die is to have the neck sizing area of the die polished out .002-.003 by a gunsmith or the manufacturer. Get an expander ball for the next caliber up and polish it down to .002-.003 over bullet diameter . Or if its a Forster die they do now make expander balls for their dies that are larger than the normal bullet diameter used. Final fix is a bushing style full length die from Redding, Hornady, or RCBS and get a bushing ( Redding bushings will fit all 3 ) that is .002-.003 under the .276 measurement on a loaded round.
