Hi

I mounted a Simmons scope on my 10 22 and took it to my near by indoor range to zero. At 25 yards my shots were down and left and it seemed to me that the windage and height controls did not give me enough adjustment to move my patterns up and to the right to zero the target. I spent an hour and could not get it. I'm a total beginner, never zero'd a rifle by myself. I was not prone and the shooting position was not the best but I'm wondering if My mount is that far off? Does that happen?

I modified my ruger by swapping in a tapco stock, added a low profile utg mount and accushot profile rings

I'm going to go back to the range next week and give it a shot but any guidance would be greatly appreciated. I want to get the rifle zero'd before I go do appleseed in April

Thanks
