[QUOTE="bruce_ventura, post: 850384, member: 34084"] Yes, this test should work as you described if the rifle is held in a vise rigidly enough that the point of aim doesn't shift when handling the turret. I use a different method. It requires a custom alignment tool that is still in product development, but the optical geometry is essentially the same. If the scope has a flat machined surface on the turret housing, it should be square with the turret axes. I reference off that surface using an accurate level. Then the turrets should be plumb to within the accuracy of the level. When I view the plumb line through the scope, I can immediately tell if the reticle is square with the turrets or not. I assume you plan to use your rifles in the field, and not just on a bench. If so, I would attach the anti-cant indicator while the rifle is still in the vise. [/QUOTE]
