I would hazzard a guess that the barrell and the scope mount screws in the reciever "do not look the same way", ie they are not perfectly lined up.

This is not that unusual with some rifles even some new made ones.

The barrel could be a little wopper-jawed in the action, or the scope base screws might not be perfectly alligned on the top of the reciever, or a little of both.

If the rifle shoots good, and the impact point does not move drastically as the barrel heats up then I would not worry about it at all.

From the groups you are getting I would think the barrel and bedding are good.

Basically if it shoots good do not try to fix what ain't broke.
