Thread: How to calculate shooting angle?

I have strelok which I validate my loads in conjunction with, out to 650 odd yards, my range finder has tbr and different loadings for different bullet drops, I compare and trial and error between the app and the range finder to figure out at what point is too far for an accurate reading off my range finder, at that point I use my app solely. At this stage 450 yards is about a quarter moa difference between my range finder and app. Angles are always a funny one, gravity only works vertically, so the steeper the angle the less gravity your bullet is travelling through is my understanding. I feel your pain, I always try to have those moments at the range instead of in the field if I can help it
