Why don't you just shoot straight up in the air then and see where it lands. Better yet use a Bow it'll be more fun!
I guess you haven't shot LR before???
The actual rise on barrel is not much .. remember we are dealing with relatively "SHORT" distances. In fact, the trip to 500yds can be done completely in scope travel if an SIII6-24 is shimmed properly.
The estimated elevation needed is 100 MOA give or take. Work out the angular change that is and then see how much the muzzle has to be raised to reach that. To simplify, this is LESS THEN 2 degs of elevation.
Do a bit of Trig and yeah, you are not aiming at the moon.
The issue isn't in position of the bore... the issue is getting enough 'up" in your optics to aim at the target. The vast majority of scopes are not designed to operate through their full elevation spec or simply don't have enough mechanical travel. But a few layers of pop can and a bit of epoxy can create the cant one needs to allow for a very high short range zero giving more scope travel to complete the trip.
For the generic 1" scope, just shim the base and/or use Burris sig ZEE rings to get to around 4ft high at 100yds with full scope down and using the top of the reticle. Now with scope and reticle, you can make up the final 50MOA to complete the trip.
Nowadays, ELR shooting isn't as hard to set up as it once was.
Try it ..... you will be very surprised.
