When gun fires, muzzle rises up with recoil. It needs to rise up vertically (along with gravity). That's what counts. It doesn't necessarily have anything to do with which part of the rifle being level.
I haven't had a lot chance to shoot long range, but that's what I do or try to do. I always use the vertical part of the reticle to align with vertical "features" appeared in the scope. A wall, a fence, a flag pole, or even a standing person. I test fire with different elevation settings. There should be little or no change in windage in the groups, otherwise I will rotate the scope tube to adjust. For instance, if the center of groups shifts to the right with increased elevation, I will rotate the tube clockwise a little and try again. When done, the shouldered rifle may look or feel canted, but I just ignore it. My perception is wrong.
