When I shoot my rifle I am sure I cant it over a little. At the minute I do not have an anti cant bubble but I have just ordered one. Am I correct in saying that as long as the bubble is level and set at level when I am zero'ing the rifle and set to the same level when I am shooting the rifle everything will be ok ??? Or do I have to reset the scope so the cross hairs are set in the same horozontal plane to the rifle ???
