To produce a drop chart, you will have already settled on a load.

I suggest printing a drop chart, as it is a great learning aid, with all the data available at a glance. You could skip straight into the ballistic calculator, but if you're new to this, you are likely to get confused and make changes to inputs that impact the outputs negatively.

For producing a drop chart, I can recommend the online calculator at JBM Ballistics.

Use that, or your preferred similar software to produce a chart of bullet drop to the maximum distance that Long Range shoots are held.

As a comparative exercise, use two or three different softare programs to produce the same drop chart, and notice how they differ from each other. JBM Ballistics seems to have more accurate math equations behind it.

Make sure to use the correct altitude and air pressure for your shooting location, as this greatly affects trajectory.

If you do not adjust the drop chart to factor in altitude induced air pressure change, you will be wasting time and ammo.

As an initial aid, copy / paste the chart output into a spreadsheet, and add blank columns - one for the correction factor and one for the corrected elevation adjustment.
