FUDD Military Precision Shooter needs schooling.

It is a reason you can say for missing at long range.


I would imagine most misses are due to these fundamentals….
1) too few shots in zero'ing
2) lack of hit probability validation in load testing (too few shots in load testing)
3)) scope don't hold zero

While all of your points contribute/are possible, I'll take THE WIND for the win. Wind separates the shooters from the trigger tuggers. "What we have here.....is a failure to communicate".....with the wind.
Moving vast distances to new terrain also contributes to misses. Paid snipers relo 30 days prior to needing to shoot to learn atmosphere, wind action on God's wind flags....vegetation, dirt,....confirm new DOPE. It's the art on top of the science that makes the impacts.
