    Nope. Mine works just right, all the way out to 125 yards.

    I did have my scope rings loosen up (didn't lok-tight the screws) and that really raised havoc with my accuracy.

    Agree. I had zero problems making my chart past 100 yds. It HAS to be something moving. Maybe disassemble, inspect, and reattach?

    Before starting, I had my bow tuned and ready using a Nightforce scope. When I was happy that all was well, only then did the Optimizer & a different scope go on. It was clear sailing. Literally no problems at all.

    By itself, a 1/16th of an inch offset would not cause the score or crossbow to shoot poor groups.

    It could potentially cause you to not be able to zero the scope because you run out of windage-control (left/right) travel, or could even cause you to damage your scope if you keep cranking on the windage knob until something breaks.

    I still suspect something is loose. Poor groups are almost always due to something being loose, or more generally that something is inconsistent from shot to shot.

    A fixed bias offset can make set-up difficult or impossible and would cause your bow to not shoot to a point of aim of your choosing. It would not cause arrows to scatter.

    Agree. Also go back to the paper and check tuning. It's quick! I once found my front rest had moved (bent) somehow, while I had spent hours looking at my rear setup. Arrows were wobbling all over the field and I didn't know it.

    Hi Mountaincur,
    Do not disregard the little one word question from Len Backus. Although he does not go into any detail to explain what he's stating, he is right on the money.

    What Len means is that when you change your distance to the target, if you do not correct your parallax adjustment for each different distance you are shooting, this will through your point of impact way off center.

    I understand you may be dealing with a scope alignment problem and that will require the rings that Buzzard Bait has recommended, but once your scope has been properly shimmed and aligned, if you ever experience the problem of POI changing for an unexplainable reason, it often relates to ones Parallax not being properly adjusted for the change in distance.

    Darn - Just imagine how much everybody would learn if we could just get Len talking more???

    Regards,
