RE: Omega X7 with a Nikon Omega scope?
Only range time will tell you if that scope will be true to the rifle. It should be very close. The problem is, not all rifles like 150 grain loads and still have the kind of accuracy you will need out to 200 yards. So work your load carefully. Then you will have to shoot at the different distances and see just how close everything is. I watched a person on a hunting show last night shooting an Omega and that scope and he was explaiining how the scope BDC worked. He was shooting out to 150 yards and swinging a target with ease.
