This is nothing "new" I have a 22-250 Sendero I got in the 90's and the rear 2 scope mount screws are not in line with each other, and the front 2 screw mount holes are not in line with the rear 2. it took an adjustable mount all the way to one side, along with .040 of Burris inserts to get the scope on somewhat center. then used up about a turn of windage to get it on. I called Remington to get it corrected and was told it was in spec. I had sold my 22-250 BDL heavy varmint with a shot out barrel and got this, wish i had just re-barreled it. It was an older action with the clip slot.
