Hunted many years ago and finally getting back into it. Hunting with a rifle from a tree stand. Let's say you zero your rifle at 25 yds so that it hits zero again at 240 yds (just an example, don't worry about the specific round & trajectory in the example). If you're shooting from an elevated position at a deer 100 yds away, would you expect the elevation / angle are going to have a neglible affect? In other words, if you were shooting level & figured the POI would be almost 3 inches higher than where you aimed for a deer at 100 yds, would it still be about the same if you were shooting from an elevated position in a deer stand (say 20-30 ft up)?
