A few days ago I took out the 338 Lapua and attempted the 2500 yard shot. So I placed the target at 2530 yards or 1.43 miles away, at that distance the bullet flight time is almost 4.5 seconds! Made a short video that I think you guys will enjoy.
I went out early in the morning to beat the mirage, luckly there was very little wind around 3-4 mph coming from the left, I dialed 2.6 mils Left. I had to dialed the maximum elevation my scope (Nightforce NXS 5.5-22×56 MIL/MIL) had at 27.4 mils then held over 2.5 mils on the reticle to get me to 29.9 mils.

Just figure = Windage, Elevation, and Curvature of the Earth???
Might even have to add or take of a little for rotation if you’re shooting N-S, or S-N
Thank you atouk, I hope you’ll forgive me for leaving that out, but its the first time I ever tried to figure anything past 800yds.
