Not sure if the stadia used for a golf rangefinder will help. The one I have (not that I've ever set foot on a golf course . . .) uses the height of the flag as the reference and is graduated to 300 yards / metres. It makes the assumption that all golf flags are the same height which seems to me like a fairly big assumption.
Anyway, the way I'd do it is to get an old Overhead Projector Pen and some clear film to cover my video screen. Then fire a paintball into a target a foot or so away, cetre the camera on the resultant splat and mark the screen with a cross to designate the boresight. Next I'd put a box the same width as a 1/6th tank at 10 yards range and shoot at it a few times. When I was happy that the elevation was correct to hit the target at that range reasonably consistently I'd put a dot on each side of the target as seen on the screen. Repeat at 15, 20, 25, 30, 35 yards range. Draw two curves, as smoothly as possible, joining the dots on both sides. Done. It might even work..
