Frosty. In my experience, 'sort of'. I have only mounted Nikon scopes in multiples, so I can't speak for other manufacturers. DSG is too cheap to provide me with proper scope mounting tools and after having my own tools magically disappear, I've developed a few tricks which brings with it some consistency. First, I make sure my mounts are properly mounted - especially when they come pre-installed. Remington is notorious for under torqued scope mounts. Second, I apply gentle forward pressure with my thumb, when tightening down the base ring. I have no torque wrench - no way to measure inch-pounds, so I just have developed a feel for it. Most of the customers I see come in with scope issues have not properly installed their rings, bases, or a combination. Sometimes, if you just 'free-wheel' while you are tightening your rings down, or under/over torque your base, you will be more off than you think. While I have not checked dials scope to scope to see if they are set the same, I am generally in the ballpark before I bore-sight. I'm not sure if you are bore-sighting, but if not - you should. A laser bore sight is about 25-bucks and can save you some aggravation. You can also go old school and from a bench, look down the bore of your barrel and adjust crosshairs to match. If you get frustrated and need some help, feel free to swing by - I seem to get pretty lucky...
