This is my first time prepping 200 pcs. of 338 Lapua Brass. I have uniformed all primer pockets, deburred inside case primer hole, Uniformed all case neck I.D's, trimmed all cases to 2.715 with my Giraurd case trimmer and weight sorted all brass.
I have run into a couple issues and would like to get some advise about what to do next. The first thing I have found is .oo1 max neck wall thickness variance on this new brass. I used a Holland Ball Mic and a Redding Case Neck Gauge. My question is, should I neck turn? I am really trying to do everthing right but not sure if .001 is enough to worry about. I might add that I do have a new K&M neck turning tool with dial indicator.
2nd, I am getting up to .002 eccentricity from the case body to the neck. This is before I have run it through any dies (Virgin Brass) I am checking these cases on a Redding Concentricity Gauge. My question is: Will my Redding "S" type dies staighten these necks? I have not tried using the dies yet, fearing I might screw up a bunch brass. Suggestions Please?
I might add that the rifle I will be using these in is a custom build from Joe Starns in Montana. Thanks in advance.
