Re: Drop Charts from Sierra not matching up.
If you're data is tight, scope high measured with a caliper, zero dead nuts on and eviro data on you can shoot your data and run it through a program with trajectory validation. I don't know about Sierra but the G7 program in the LRH tool bar has trajectory validation, you could then take the corrected data and use it in what ever program your using then make minor adjustments if needed. You could post up your shot data and someone will run it through Exbal also and trajectory validate.
