.223 ballistic mystery...

[bellavite1]

The "velocity calibration" feature does just that, but only allows a drop increase input.
To input a climb would mean entering a negative value and that is not allowed.
Therefore I attempted changing the velocity in the load data until it gives me a 2.5" climb: at 5000fps (maximum allowed velocity) I was getting about 2" climb at 100yds from a 50yds zero.
It would mean my load is more than 5000 fps...
If that was the case I would probably be dead rather than just confused...
These are the bullets I was using:

I will get an exact velocity figure out of a different rifle (to rule out any hardware issue) and try it again next week.
