Put the gun in a rest, level the top Picatinny rail with a bubble, then rotate the scope in the rings until the vertical reticle lines-up with a plumb line downrange.
You can take a plumb line to the range you use regularly and confirm a permanent vertical structure downrange is plumb. Then use that to check scopes from then on - target frames, flag poles.
I use a 1m length of white PVC pipe suspended with a weight below it as a plumb line instead of string as it's easier to see without having to crank up the magnification.
