Narrative:

The aircraft was loaded on the forward limit of the cg. Shortly after rotation; the captain pulled back hard on the control yoke; causing a tail stall. He made the decision to abort the takeoff; and touched back down. We were able to stop before reaching the end of the runway. We taxied back to the GA ramp and called operations to inform them of the incident. A member of maintenance asked us to do an elevator trim check to ensure that it was in fact a tail stall and not a control failure. The trim tested normal; operations re-released us for departure; and we left. The captain did not recognize that the initial climb would take more back pressure because we were loaded so far forward; his reaction was to pull hard on the yoke; but since he did it so fast; the airflow over the tail was disrupted. My objection to aborting a takeoff after V1 was noted and dismissed by the captain.

Title: SW4 First Officer reports rejected takeoff after V1; when Captains' vigorous elevator input caused a tail stall. Aircraft had been loaded within limits but with maximum forward CG.
