Could be several things but I would not expect it to barrel harmonics for that large of groups. A friend had one that was shooting that way in a bolt action he bought used and in trying to figure it out I took it to a friend that re did the crown on it. Accuracy was about 1.5 MOA after that. Turned out the crown was not square with the bore. Just one example of something you do not expect.
I would double check assembly and call the manufacture and see what they have to say if nothing is found with the check
