I would try to set a 20 yard pin and see if it is possible. Then try your shorter yardages and see where they hit at with different pins. I don't know much about the champion sights maybe someone else on here can be of more assistance as to adjustments with that particular sight. As stated before. Just remember to follow your mistake Shoot left move left and so on. It is the same for up and down. Good luck and let us know how you made out. Oh one more thing. If you need more room you might be able to move your pins within the sight window to gain more room if you need it.
