It is possible but the adjustments should be 1 click = approx. 1/4" at 100 yards (in your case it actually moved 2" after adjustment). Is it possible you actually thought you'd clicked it once and actually obtained more? Not sure why you'd click it 1 click for 1/4"to try to move it an inch in the first place? Just wondering if at the range, muffs on, etc you actually over shot the adjustment. How many shotsdid you fire to the new POI and verify its grouping?
