Thank you, the beauty of FR, ask and you will receive an answer.
2,500 yards equals 1.4 miles if fired at an angle of 12.5 degrees.
I recall some maximum distances listed in The NRA Fact Book. For some reason the angle of 37 degrees is rolling around in my near empty head as the firing angle for maximum range in some calibers.
Dunno where the fact book is now (the wife hid it again).
Have you tried some steeper angles in your program?
I like most of us here are talking about ballistics,,, the most important thing is this guy did not fire into a backstop
