    123 scenars
    COAL 2.788 15 thou off lands
    6.5x47l, 26 inch shillen shot of atlas bipod
    300metres
    12 shots from 34.7-38 grains varget no pressure signs at all
    Just what to check with the pros that ive got this right with the nodes, shots 4,5 and 6 (35.6, 35.9, 36.2) measured right on 1 inch of vertical shots 8,9,10 (36.8, 37.1, 37.4) measured just under half inch vertical.

    Iam thinking nodes at 35.9 and 37.1 ??

    On another note all my cases have black soot around the neck and shoulder. I read that this can be caused by low pressure however this cant be the case surely with mine as i still had soot at 38 grains of varget?? It is a tight neck turn chamber .286k neck. Is this causing any damage to my gun or is this just cosmetic?

    37.1 is my pick.
    Soot on the neck ? Since you already turned the necks either skim them a little more or anneal the brass.

    I've had soot on lapua brass in tight and loose neck chambers.

    Never had any soot on Winchester brass.

    Clean the neck of the chamber real good and soot might go away.
    I would shoot the ladder again to compare
    with first one.

    Thanks guys I will have to look into a torch to anneal by hand as I can't afford a machine ATM. Does this soot do any damage to the gun in anyway that you guys know of ??

    I'd do more testing around shots 8,9 and 10.
    +1 re Win v Lapua brass, I get soot on half the neck with Lapua but nil in Winchester, no explanation though....
