You don't want a rifle that takes this much windage to get to zero (assuming optical center of the scope is correct).
Could be any number of things causing it from bore curvature, bent barrel, and incorrectly drilled/tapped mounting holes in the receiver.
Bottom line is that you end up with a "zero" that will change based on distance and this isn't acceptable.
Just like a rifle with a scope mounted off the centerline (like a milsurp with a side-mount), the line of sight with the scope, and projected bore axis will cross at only one point in space and it will vary with range.

Even with no "wind", you will need a different windage adjustment for different ranges. It can be dealt with by getting that dope and making the needed adjustments, but it's an unnecessary PITA and shouldn't be on a new rifle.

They probably won't tell you whether they replaced the barrel, receiver, or both- but hope it shoots straight when you get it back.
