On a Horton, on your dial a range, set it at # 2 and sight from there,that what the company told me once when I was experiancing trouble. My scope was a multi-range scope.

And like that was said in a previous post, use a rope, or a crank, to pull up your string.The stringHAS to be pulled up straight, to make sure the flight goescorrect. That way you are shooting the same thing everytime ~~~
