center shot guage , 100 grain tip
I wouldn't trust any laser or guage,I trust eyballing more than those methods.My guess is the centershot is off.Measure to the center of the arrow from inside the shelf and someone with that model might be able to measure theirs to see if you are close.
I would also try a 125 grain tip.
