I put a Sure-Loc 400 with a Viper Scope on my Pantera and experiencing tuning problems. I moved the mounting bracket to the left on the adapter plate and had to move the horizontal bar to the farthest right of the slide and turned the micro knob to almost max out to the right. I cannot get the scope pin, arrow, bow string, and riser to align perfectly. When shot the arrow moves to the right of the target and I do not have any more adjustments available. Verticle appears to be fine but when using the sight pin, the arrow moves to the right. Any ideas as to what I should do next? Thanks.
