[QUOTE="Hondo64d, post: 1306940, member: 1390"] Send three fired cases to Harrell's Precision and have them send you a custom fitted FL bushing Die. It cost no more than a Redding FL bushing die and will be a better match to your chamber. A .288 bushing is a good place to start for proper neck tension. I like the Forster micrometer adjustable seating Die. Cheaper than the Redding, but gives up nothing to it in terms of precision. Get a case bump gauge to measure shoulder set back. There are several manufacturers. You can even measure shoulder bump with a caliper and 9mm case, but it is not as refined of a method. You are wanting to push the shoulder back about .001 to .002" but ultimately your rifle will tell you when sizing is optimal by how much effort is required to close the bolt. I like just barely perceptible resistance on closing. A bushing die lets you choose how much you squeeze the neck down by what size bushing you select. Conventional wisdom says you want about .001 to .002" of neck tension. That is a sized neck will measure .001 to .002" smaller than a loaded round. For ammo that will be fired from a magazine, I prefer .002". John [/QUOTE]
