    hey Striker

    what i have done is completely set up a new 'rifle' + new 'ammo' + new 'target' from scratch - manually entering only the necessary fields in case previous changes have somehow affected it. same result.

    checking my 308 table there is a similar issue - sighted at 100y but the damned applied ballistics drop chart tells me 1.4in at 100y


    if anyone knows the ins and outs of this app please shout - otherwise i might have to try another app

    Using Shooting and plugging in your data, plus a 0.7 elevation correction I got EXACTLY your results.

    Try running it thru JBM and see what you get.

    here are the full details.

    the only info not showing clearly is the bullet BC of 0.392

    i can't find any reference to 'scope 'true magnification' so just used 9x which is what i sighted in at - i have a zeiss conquest HD5 3-15x40 if it is scope specific

    thanks for having a crack zimmer, i don't understand the 0.7 elevation correction, i can put in a correction on the AB app and sort it too, so any idea how this fixes the issue i have? unless i am understanding this wrong i just don't get why we would need to add a correction when i am zeroing it at 200y

    thanks for all the help!

    @LOC put everything in Shooter and it shows height at 200 as 0.0 drop at 250 at -2.9" Sorry got no idea about how to put what is on phone up on to the computer.

    Could be the difference between your powder temperature and your shooting temperature.

    If you have your pressure set to absolute then your altitude needs to stay on zero.

    As a side note, I've just been down the verification process of my scope dialling , followed the tall target test as per the link

    https://m.youtube.com/watch?v=12Wf0Cuwwi8

    Turns out I need apply a .9 ish, elevation correction factor, need to now validate that further
    Went to buy some camouflage trousers the other day but I couldn't find any.
