    This addon introduces a new item to the game, which helps you to calculate firing solutions.

    --- Features ---
    * Supports most rifle calibers used in ACE
    * Supports manual entry of gun data
    * Multiple Targets (up to four)
    * Rapid ranging with a Vectronix Pocket Laser Range Finder
    * Range Card Generator
    * FPS corrected wind drift
    * Target Range Estimator
    * Target Speed Estimator
    * Clicking Memory
    * Handles both English (Imperial) and Metric units of measure
    * Display in Mils, MOA, Clicks
    * Calculates bullet drop, wind drift, lead (moving targets), time of flight, remaining velocity, remaining energy

    --- Basic usage ---
    Step 1: Select ATragMX in your ACE self interaction menu
    Step 2: Select your cartridge (GunList / Arrow up/down buttons on the PDA)
    Step 3: Enter the target range (TR)
    Step 4: Enter the inclination angle to the target (IA)
    Step 5: Enter the cross wind (WC)
    Step 6: Enter the head wind (WH)
    Step 7: Enter the target speed (TS)
    Step 8: Enter the FPS of the client who shoots (if known - otherwise leave empty)
    Step 9: Select your scope unit of measurement (MILs, TMOA, SMOA, Clicks)
    Finish: Click Calc

    --- Target Range Estimator usage ---
    Allows you to estimate the range of a target if you know both it's real size and image size in your reticle.

    --- Target Speed Estimator usage ---
    Allows you to estimate the speed of a target if you know it's range and the time the target takes to pass a certain number of hash marks in your reticle.

    --- Relative Click Memory usage ---
    Step 1: Calculate a firing solution
    Step 2: Adjust your scope accordingly
    Step 3: Click the "Update" button
    Step 4: Calculate a new firing solution
    Finish: Use the data in the "Rel" column as holdover or to adjust your scope

    Great Ruthberg

    Have you ever considered adding Dagger Ballistics ammo to your library?

    No, but you can modify existing gun profiles by changing the parameters in the main menu gun column to get an adequate fireing solution:



    WC = Wind coefficient
    BW = Bullet weight in grain
    C1 = Ballistic coefficient as airFriction * -1000
    MV = Muzzle velocity in m/s (metric units) or feet/s (imperial units)
    ZR = Zero range in m (metric units) or yard (imperial units)

    Edit: I forgot to mention that you need to press "Enter" while your cursor is in the zero range input field to "re-calibrate" your zero after changing gun parameters.

    Hey Ruthberg,

    I´ve done as you told but it doesn´t allow me to set zero Abs Elev as you can see here:


    As a result, my desired 300 m zero is not "zeroed" as you can see here:


    Any clue?

    Thank you Ruthberg.

    OK, now I´ve done as you told but the results are still a bit out. Bellow you can see ATrag results compared to real game values (ACE wind drift turned off):

    Dist ATragMX Game
    m MIL MIL
    100 -2,0 -1,9
    200 -1,0 -1,1
    300 0,0 0,0
    400 1,2 1,2
    500 2,7 2,5
    600 4,1 4,1
    700 5,6 5,7
    800 7,4 7,6
    900 9,5 9,7
    1000 11,7 12,1

    The difference of 0,4 Mil´s at 1000 meters is 0,4 m or 40 cm or 16". Possibly a miss, not to mention wind.

    Would you mind sharing your equations please, so that we could think together?
