    Default how many of you shim your scopes?

    If you have dialed your scope to optical zero. Did you need shimming?

    I just did my optical zero and was @ 22m 1cm high and 2cm left.

    I tried shimming but then I got decent mounts and removed the scope rail. The standard rail on the Hammerli is...well...poor.

    Counting the revs on turrets and dividing by two probably wont be optical zero.
    You need V blocks and the rotating of scope within to set.

    Now all scopes are different, some require tilt some dont.
    I know of one scope in use over there that will require 3.6mm tilt over 150mm whereas other require nothing, see the point!
    Theres no point making or buying a rail to find out its wrong. Ideally need to try scope on said rifle and shoot at your zero, see where it lands.
    A suitable rail can then be made up by a competant person to compensate for this error.
    The only other way is adjustable mounts but there again all rifle manufacturers cut their dovetails different both in width and depth. A few thou its real sloppy, not good even when clamped.

    If its going to be made, do it right ro not at all.

    I've shimmed one of my scopes.
    another way of finding optical zero is to put you Objective lens on a mirror, and you will see two crosshairswhen you look through the scope. simply line up the crosshairswith the turrets and there you go. it's easier with an illuminated reticle.

    Never heard of that one Gary but thinking about it you could get it some where near.
    Small enough mirror could do it on gun.

    It may be several months before i could confirm this works.

    just make sure the objective end is flat against the mirror.

    We do have a mirror in the house but scared what we might see.

    All the decent scopes here are adjusted from factory optical zero, very few are except quality scopes.
    If i get time in a few weeks i will optically zero in V blocks a T50C, see how that compares to a mirror.

    I would be grateful if you let me know what you find Jon - I've never used V blocks - i'm keen to know if you see a difference.
