I like Greavous' advice.

Another thing to do is check the bow' s tune.

Do you shoot carbon arrows? Have you bought new arrows or are you still shooting the same ones you got 5 years ago? You shoot carbon enough and they' ll wear out. Group sizes will go to pot. As hot and heavy as some people try to deny it, that' s a true story. Try some new arrows if it' s been awhile.

I' ve had a few bows in the past 5 years that were very particular about how they wanted to be gripped. One bow wanted two, and only two, fingers wrapped around the front of the handle before it would shoot consistently. Not one or three, but two. Another wanted one finger. I' m not talking about maybe a half inch in group size, I' m talking MAJOR malfunction with arrows all over the target. But if I held those bows the way they wanted to be held, they shot just as good as any bow I ever owned.

I got tired of the bows telling me how to shoot. I got rid of them. Life' s too short to get stuck with a bitchy, nagging bow.
