Just wondering if you tried to bore sight the rifle before taking it to the range? That would have given you an early clue.
I recently bought a .223 Handi and, amazingly, when I mounted the scope and put the bore sight on it, it was only off 3-4 clicks to the right and a couple clicks high. Still have to get it zeroed at the range, but what are the odds the scope and rifle would match up like that out of the box? Lucky.
