    New label or ?
    Set air pressure for the average of your hunting weather encountered ie 28 inhg

    Altitude is irrelevant as an inputted value compared to actual/absolute air pressure.

    Yep, either average your air pressure for your usual hunting areas, a different label for specific conditions or have MOA printed on the label also so that you can input data into a ballistics programme and dial accordingly.

    Awesome work, can't wait to play with them

    The straight set will go on the smallbore rifle and these on the fullbore.

    Spot on Matt. Ive spend time sorting what air pressure i should out for my own label. Ive also added MOA to it so i can run from a ballistics app if i need to at some stage

    BDC plus cheat-sheet eliminates the need for ballistic apps in changing conditions.
    Just pre-calculate the DEVIATION from your BDC.
    Then you can look at the weather and say "ok, today I dial range + 2 clicks..." and you'll be spot on and much faster than a ballistic program

    Here's how to setup your BDC to work inside your weather range.

    Always happy to share:
    R1 = (C1(R1-R2))/(C1-C2)

    where:
    C1 = D1xpie
    C2 = D2xpie
    R1 =Radius@D1
    R2 =Radius@D2

    Who said maths wasn't going to be helpful in real life?

    I "simply" made a model in 3d and unwrapped it as a 2d surface. Maths would be probably be simpler, but modeling is fast for me.

    I'm guessing that the different layers of the ranges are for different turret revolutions. Do you find you ever forget to turn the turret back and forget what revolution you are on?
    Those Burris C4s are awesome scopes, way better than they should be for the price.

    I brought mine in the US while there for work. Worked out about NZ $420 at the time. About doible that here.

    Yes, different layers are for each revolution and also have the zero stop information printed on it. "Zero 28 minutes from the top"
