I have a mini-14 ranch rifle with a red/green dot scope that is giving me a real problem zeroing it. I used a bore sight at 10 yds and had the point of impact at 2 inches high. I also zeroed the iron sights at the same impact. I went to the range and shot on the 50 yd range and was not even on the paper. I tried various adjustments to get it on paper and finally did but all adjustments to the scope would move the impact to a point that was contrary to the adjustment arrow directions. Any thoughts on this? It seems to me the scope is not responding to the adjustments correctly.
