ok mate but try this if all is ok then its something your doing the thing i found i was doing is i lost my focus on the target i was swapping my eyes to the pins this was throwing my shots ( make sense?) if all is ok with the bow go to ten yards and get your grouping back by makeing sure you are concentrateing on the target only not the pins its what i did and im back on target what did it was i have been sorting out so many other bows for club members my head got screwed with all the things wrong ( shops here in uk have forgotten about customers and are only worried about money) and forgot about me and my shooting it will comeback mate just try you can shoot you can hit the target you know you can ..... now just tell yourself that
