There are still to many variables to say.
If I'm shooting across a canyon here in Idaho, good solid prone position ,I can see the terrain of the canyon well, I have good wind speed and direction via kestrel at my location, I can see vegetation and movement of it and am familiar a bit with the area, and my target is mid to top 1/3 of the hillside, I like my odds in the 70% realm.
Now, new area, I'm at the top 1/3, can't see vegetation movement well, switching wind from 1-3 o'clock, target in the bottom and up canyon from me, I don't like my odds. There's just so much nuance to shooting that far
