    New 338 Fed brass, resized (it came in plastic bag), then checked on Redding Concentricity Gauge. With zero on dial indicator at 12:00, 75% of brass was under .0015 variance mid neck, but some went left and some right of zero right under a thousandth. So most was .0015 to .002; and yet maybe 25% of the brass was about perfect, hardly no deflection. So I marked each piece. Now the last 25% that was over .002 wasn't over much. Should I even bother turning the brass that was between .0015 - .002 variance?

    If it is a factory barrel I probably would not waste my time as it is highly unlikely that you will see a noticeable improvement.
    If it is a custom job that is a different animal altogether.
    Yes, in that case.

    +1, turning necks is something I do only if I absolutely have to, such as forming one case out of another, like making 243 out 308. It take a very accurate rifle to make this labor pay off.
