    Ballistics software

    Gday guys. Ive tried downloading heaps of ballistics apps, and the pro versions etc.but i cant seem to find one that will base calculations off a POI above bulls eye at 100. I run my 308 at 3 inches high at 100 for maximum pbr but ideally would like to be able to input that 3 inch high data and get ballistics tables from that. I dont really know where my zero is. Have i missed something or a programme that does it? Or do i just need to keep going back until i find zero on the range? Cheers

    Have you considered working out (shooting targets) what distance you are actually zeroed for when 3 inchs high @ 100. If you use that as your zero distance then things should line up roughly.................. maybe??

    Yeah, nah. You'll have to just dial out the distance until the "100" column is 3".

    Also if you don't have chrony data and a proper BC number for your load/gun, you'll be plugging in erroneous data, which will become a bigger deviation at longer distances...
    Also, nothing beats actually shooting at varied ranges to know just what.

    ^^^ What he said, just change the zero distance until the program says three inches high at 100.

    Shooter allows you to get a table with a 3” high zero at 100yds. You just put in the zero range as 100yds and then say the vertical offset is +3”.

    Shooter does what you want easy as and I assume Applied Ballistics. I'm sure Strelok does as well but have deleted it from my tablet so cannot check. A Strelok user may comment.

    I use pointblank online and just keep changing zero untill my impact at 100 matches what it actually is...........so quick n easy to use and was eye opening with .223 so much so I changed that to much closer to 1" high with much better results on game.

    Just looked at Strelok and it also gives you an option for a zero offset

    So does JBM Ballistics.
    From the guide in the program -
    Zero Height
    The height of the zero point at the zero range.

    I use Shooter but JBM is one of the most comprehensive available.

    Just had a look at it and tried some calculations.
    Like it very much.

    Zero offset on Strelok works well for your situation.

    Strelok also does “recommended distance “ which calculates the zero which will give you the greatest point blank range for a given target area.
