I need some help with my muzzy zero effect. I have watched the video (a couple of times) and set the thing up like they show on the video. I took my bow out and it appeared to paper tune well. When I began shooting the bow in the back yard at targets my arrow looks to have really eratic arrow flight. Hitting the target at all kinds of angles. I know this is not right. I shoot a Mathews Q2. (Anyone set one up on a Mathews Q2?) I set the rest up with the pivot arm in the whole closest to the archer (as stated in the video) and the rest portion in the whole closest to the archer as well. I am not sure if this matters or not. I shoot 70 lbs with a 29 inch draw and Game Tracker Carbon Express Terminator Hunter 6075 arrows with a 100 grain tip. What am I doing wrong? ANY help would be greatly appreciated.
