[QUOTE="ELR Researcher, post: 1118747, member: 19541"] Learned long ago that it is easier to understand such issues if you exaggerate the variable - since its easier to visualize and your looking for the effect of any change in the variable. Assume a rifle cant of 90 degrees (my exaggeration for this discussion). The vertical distance between the centerline of the barrel bore and the centerline of the scope is now zero. Yes, you can make a hit but the POI will have moved (if you were still using the same POA) - how much depends on the distance and actual projectile ballistics given the load and specifics of the platform. For the questions not asked: Yes, its worth while correcting for the cant before pulling the trigger. And, yes, its worthwhile having and using a good, properly installed, cant indicator and properly aligned scope. [/QUOTE]
