Matt Dubber has a good video up today on high angle shooting. He talks about how to calculate your shot for extreme angles. Most of us who shoot in mountains and shoot more than 50 yards are familiar with the problem. Matt does a better job of explaining it than I would. He relies on modern technology to plot out hold unders. where back in the day pre-internet, we knew it was a factor but had to just shoot enough to learn it. I once missed a coyote because of not holding under enough for the extreme angle.Technology is great.
