Thank you very much for your prompt reply. I believe the scope is mounted correctly-the guy at Bass Pro Vaughan Mills did it. I can move the back of the scope up the half inch like you said. I've tried everything with the elevation screw on the scope. I've tried most of the settings on the dial-a-range. My point of impact is always below my crosshair at every range. When I use judo points it seems I get the least amount of drop-POIis exactly onthe "first" aim point at 20 yards. However, using 100gr fixed blades the POI is right on the "second" aim point (the middle one)....
It is a brand new Summit and my first crossbow. I've been enjoying it very much despite this issue. The horizontal accuray is perfect every time providing I cock it evenly, and I just use the other aim-points as a form of compensation. I'd like to use my crosshair though, obviously lol. Thanks again for your help.
