I was reading an article by Bill T. on the Horazontal Bowhunter sight , and he stated the a well tuned Compound will drive tacks (Squirrel)
it was a very interesting article it addressed isshues like string jumping , broadheads and other interesting info..I think a lot of a bows accurcy has a lot to do with the person shoting it,, you could have a great bow but if the person shoting cant shoot then it dosent matter,, and also you could take a good shotter and he could get bullseyes with a nad bow by adjusting his shoting,
