If you serious about this get a long range mount with about 20moa of inclination(?) built into it. Most mildot Scopes don't have enough adjustment to handle this amount of drop.
Also the highest velocity ammo you can find will aid you. The bullet becomes unstable as it drops into the subsonic range and starts to yaw. Maybe something like the aquilla interceptor highspeeds would give you enough velocity to keep it supersonic at this range.
Interesting project, keep us updated on your results.
