Looking for advise. I just purchased a new Winchester model 70 Super Grade in .300 WIN Mag, Leupold 4.5-14 X 50 LR, B&C scope, Leupold std 2pc bases, Leupold std high 30MM rings. I installed the bases and rings, aligned them, tried to set the scope in them and it won't fit. The distance between the rings is about 9/16" to great to fit the tube of the scope, to say nothing about eye relief adjustment. I assume Leupold designed these bases to work with there scope. I have checked the Leupold web site and as far as I can tell I purchased all the right components. I tried turning the rear base around and found that it hangs over the opening of the receiver about a half inch that way. I know that Leupold makes extended rings that would solve My problem but that seems a little weird. Has anyone else run into this? Did I purchase the wrong basses? Did Leupold design basses that can't be used with a Leupold scope? Would a one piece base space the rings closer together, could not find specs on the Leupold web site? I e-mailed Leupold last night but have not heard back yet, thought someone hear might have a better Idea. Thanks.
