I think that thats a reasonable shift for a 20* change. Wouldn’t be surprised even with .mil ammo. Snipers that I have worked with collected temp and altitude data when working up DOPE books for their win mags. Probably more stuff. How they organized that data, I have no idea.
Sidebar: Mortar ballistic computers take into account all sorts of weather data, and it can make a significant difference.
