Have you tried these programs for your trajectory plots:

If you have accurate data for your zero and three other ranges (in clicks or inches POI from your zero) these little programs are gems. Data retrieved can be optional for mildots, clicks, inches or moa. Dave Eades wrote them years ago.

They don't depend upon one knowing MV, BC, accurate sight axis above bore at the muzzle, etc.

Of course as you know, time of day (temperature) altitude and wind direction can confound any predictions including charts constructed from data actually collected in the field on a different day, or even the same day at a different time like early in the morning before competition.

You should be able to open them from the above references.
Left click the references above, then go down to the one with the ticked box for each. Then right click for download prompt; and left click to download - they are very small programs. .....

These copies are courtesy of Greyskull (Adam) on the NZ Airgun Forum. He used one of them to set up in South Africa Worlds at 4,000 ft and totally unfamiliar environment. He had just one hour to get sorted and found it spot on.

I often use them at the farm with changed rifles or different rifle tunes and they never fail me, even at extreme ranges.
Kind regards, Harry.
