AB Mobile Giving Incorrect Data

[RyanM]

I have used AB Mobile for a couple or years now and it is great however my last couple times shooting my elevation has been way off.

I am running a 105 Berger Hybrid at 2,850 at 4,000 density altitude and 80 F.

The app is giving me 2.5Mil at 500M (550Y) but I am really needing about 3.1Mil. Strelok spits out 3.15 and the Berger online calculator gives me 3.02.

Any ideas as to what is going on?

I have tried deleting and redoing it all and it comes up the same.

Thanks!

Bad input somewhere,

lots of screens to menu through to figure out where to find it, try building a new track with the right data and see if it's different

Problem solved - I am retarded...

You mind telling us. Would help those of us that are trying to figure out their own errors.

Haha yep no problem. There is the zero height input (1.5" for me, centre line of bore to centre line of scope) and then there is the zeroing info. I had 1.5" in there as well so at 100M I was impacting 1.5" high according to AB (well I told it this at least).

Once I got my zero height to zero things all lined up again.

I must have been effting around in there one day and got confused.

Thanks and it happens for certain

FYI,

Cause I see this a lot, that 1.5" for Sight Height is the default, you have to actually measure your sight height (Center of scope above bore) and input that real value ... don't use the default 1.5" is not necessarily correct
