And that is the whole point--if cant is induced, accuracy at range will be affected. Question is how to know if it IS perfectly level.The rifle and scope should be on the same plane so that the scope is always on top if you set it up so there is cant it will at some point not be accurate as when you dial for elevation it will move in windage. That why a long range target test is needed to confirm tracking. If you don't shoot past 400 it's not a big issue. If you shoot further then it should matter to you! There are videos out there to help the only cost is ammo and time.
