If you level the gun to the scope and you cant your rifle (lets exaggerate) at 45 degrees, then your scope is canted 45 degrees to plumb. If you want to move your POI 1" right, you have to dial both your elevation and windage. I'm not saying it's the best and only way to do it, just another option. I personally would rather have a level scope to the rifle and work on shooting the rifle completely level. Some people need adjustable buttpads where the cant can be adjusted in order to accomplish this.
