Re: latter testing.
Whatever that top left corner is (2nd picture), I'd load up 3 more to see if the left and right were just human error. If it shoots that flat again, but left and right seem to be out of whack, adjust your bullet seating depth, or bed your lug and action on your rifle. If it's already been properly bedded, then tinker with seating depth.
