I felt it couldn't be "practically vertical,"so I checked a ballistics calculator. Sure enough...coming in at about 65 degrees.

I don’t think its that steep. The flight time is roughly 3 seconds. The terminal velocity is still upwards of 1300 ft/s. The vertical velocity will only be 1/2*g*t^2 (g is gravity at 32 ft/s^2) and that not accounting for starting with a positive (up) vertical velocity due to elevation adjustment (about 65 to 70 MOA). SO vertical velocity at impact is less than 144 ft per sec (1/2*32*3*3) and horizontal is ~10 times that. The image you posted is not to the same scale in horizontal and vertical.

Your chart has around a 60:1 vertical exaggeration.

If you stretched it out horizontally 60 times I think you would be down to a degree or so angle at range.

Check your scales, more like 34 minutes from horizontal and still booking on
