    I really like this app but can't tell what problems you are having from the OP or photos. You need to fill out profiles for each rifle, then each load individually. The ballistic coefficients are available within the program. What data have you filled in? Don't worry about bullet length and some of the more obscure measurements but make sure you have entered the correct ballistic coefficient, velocity and zero range for each cartridge and see of the figures make more sense

    this is how I have done it... sorry if this is teaching my granny ...

    click on firearm and then the + at the top to add a new rifle
    name it what you want
    you should have firearm data as a title with barrel twist below
    add in the following data
    barrel twist 1 in 9
    twist direction right
    sight height 1.5 in
    sight offset 0
    elevation unit MOA if you have a scope with inch clicks
    elevation turret grad 1/4 if each click is 1/4 in at 100yd
    windage unit moa
    windage turret grad 1/4
    lead unit moa
    elevation correction factor 1.0
    wind correction factor 1.0
    then click save

    then go back to the previous screen titled firearms and click on the one you just entered
    should then see your firearm listed with a blank ammo slot below it
    hit the blank ammo tab and then the + at the top
    hit from bullet library
    choose calibre
    choose your exact bullet type e.g 129g sst
    on the next screen type in the muzzle velocity
    then scroll down and enter your zero range and zero height ie how many inches high your bullet hit at that range
    leave the rest of the parameters as they are and hit save
    hit done then shooter then calculate
    you will probably get a table, if you click the solution at the top left you can spin the wheel to any range you want and this will alter the table as well

    let us know how you get on, I have tried several ballistic apps on my iphone and find shooter the most useful, obviously the more data you can put in then the better it should become
