So as i'm developing my long range hunting skills I got too thinking. Most of my hunting last 20 years has been in places with relatively flat terrain. I grew up hunting out west in more mountain areas before long range shooting and hunting was common. Now I'm getting ready too head out west again. So here is where my question is heading. So lets say I'm on top of a ridge, I have a animal somewhere around 500 yards below me. The use of angle compensating rangefinder tells me that with my rifle and load I need too hold for 400 yards too compensate for the downhill angle. I have a 10 mph wind crossing left too right. My wind chart says hold 2.5moa into the wind at 400 yards, but the animal is farther away. Not being totally sure how far away, how do I figure a accurate hold?
