I'd like to get a single piece base for my Win Model 70 long action but I can't find one that fits. My action has a factory clip slot that makes the dimension between the two inner most holes close to 4.235" center to center. I picked up a single piece Leupold
base but the rear mounting screw sat right over the clip slot and not even close to the hole. I'd prefer a Weaver/Pictnanny base, but at this point I'd just be happy getting a scope back on it.
