I the case where I shoot in order to establish if my scope has any cant, I believe I know the answer, but wanted to confirm. I set up a plummed target at 100 yards. In set up, my bolt rails and scope turret tops were leveled perfectly. I shoot a 100 yard group at zero then shoot a group with 20 MOA of elevation. The results show I have 2 degrees of cant with my 20 MOA group. Rather then turn my scope to correct this, I adjust the bubble on my Flatline scope level to bring my group to perfect plum. Is this acceptable? Thanks for any feedback.
