    My scope has 1/8th inch of movement with each click at 100 yards.
    Is the a chart some were that will show the movement per click out to 1000 yards.
    Or is there a way to figure this out?
    Thanks for the help

    .125" X number of clicks dialed X distance/100 = inches of movement at X distance. .125" @ 100 = 1.25" @ 1000.

    Example, how far will 10 clicks move me at 500 yds?

    .125 X 10 X 5 = 6.25"
    -------------------------------------------------------------------------------------------
    Example, I need to come up 8" on my 900 yd target to be dead on, how many clicks?

    8 / 9 / .125 = 7.1 clicks
    ---------------------------------------------------------------------------------------------
    Example, the wind's gonna blow me off 16" at my 400 yd target, how many clicks do I dial into the wind?

    16 / 4 / .125 = 32 clicks or 4 MOA on the dial (assuming shooters moa or IPHY)
    -------------------------------------------------------------------------------------------------
    Example, I am 3" low at 200 yds and want to be 2" high, how many clicks?

    5" / 2 / .125 = 20 clicks (or 2.5 on the dial)


    Everything will reverse calculate if you need to figure something different.
    With some practice and some experience it will all click.

    At 1/8 inch per click at a 100 ,so 8 clicks for 1 inch at 100. So I figure that every 100 yards should be 8 clicks, or 8 x 100 = 1000 yards.
    I don't shoot past 500 yards so I'm guessing.
    I don't know if your scope will do this for 1000 yards shots!
    Plus I have not seen any scopes that have 1/8 inch movements, but I haven't
    ever looked for one either.
    Good luck. Some of the long range shooters will be able to give you the correct answer.

    You can take the MOA times 8 and it will give you the clicks. You will need to verify actual shooting data in the field, but a ballistic program should get you close.

    (0.125 x number of yards)/100 = click value for that number of yards

    I want to add to this question?

    My millet scope is 1/4 inch at 100... I have the strelok app on my phone. It gives me moa, mrad (reticle), clicks, and inches of drop. If I look at the moa vs my scope it kindof makes sense. But for example at 600 yards it says to adjust 7.96 moa or 31.8 clicks for 50 inches of drop? The numbers don't really match up in my head and I THINK ill go off the moa measurement for my scope but am not sure. Could someone add to this?

    your scope is MOA, so you would just dial to the 8 and that's it for elevation. I have a Millet with 1/8 MOA clicks. Something you can do to make your life easier is verify your data (vel, drops, G7 BC) and get turret tapes from this guy

    What needs to happen first and foremost with any scope intended to be dialed for range (after load development and before shooting at long range), is to confirm our clicks are the exact amount advertised, or at least figure out how much the real movement is. Alot of them are slightly off from advertised by time we dial in enough clicks to make a LR shot.

    Example; last one I did was .375 IPHY instead of the advertised .36 IPHY

    We can simply set up a tall piece of cardboard at exactly 100 yds.
    Shoot 2 at a bullseye on the lower portion of the board.
    Dial up 20 MOA worth of clicks on the scope.
    Shoot 2 at the same bullseye you shot before.
    Measure the distance between the centers of both groups with a tape measure or yardstick. Hopefully this is vertical too or the scope needs canted.

    So wheatgerm in your case, you'd take the measured distance from the target and divide it by 80 clicks that you dialed to figure your true inches per click.
    After that, we simply use what option the program gives for what is closest to our real and true click values. In my example, 1/10 mil was closest, but I was able to put in a custom click value to match even better.

    Hopefully this isn't too confusing, never claimed to be a writer.:)
    In your question, you asked about 50 inches of drop at 600 yds.
    A true MOA is not 1" at 100 yds, but 1.0472" at 100 yds.
    1" at 100 yds is IPHY or Shooters MOA.

    So, 50 / 6 = 8.33 IPHY
    or, 50 / 6 = 8.3333/1.0472 = 7.958 true MOA
    or, 50 /6 = 8.33/3.6 = 2.3 Mils

    So round about back to where we started, we need to know first off just how much our particular scope is really moving when we click it, because they rarely specify if it's IPHY or true MOA when they say 1/4" per click. It's the small fractions off of that amount that add up to a bigger number after we dial alot of clicks.

    Seahawkkid, this click test should also be done on your scope. especially with it being 1/8 per click. It takes you twice as many clicks to get the same drops doped out as wheatgerms scope. So, any difference from advertised is doubled in your case. However, the errors or differences may be smaller.

    Appears I was typing same time Joe King was.
