You have a lot to learn grasshopper !!
A friend of mine started shooting with us several years ago and probably was shooting about 7" groups at 20 yrds !! He didn't have a consistant anchor, his draw length was too long, and he was torquing the bow !
I taught him how to anchor , change his grip, and not punch his release !
After about 2 hours he was keeping them within a 4" circle at 20 ! My other friend put his bow in a press and shortened the draw length and made some small adjustments to his rest and sight ...........and he got down to about 2.5-3" groups within a week of shooting with us !
Anyway.......there is a lot to it ! You may want to go to a pro-shop and see if they can work with you and your set up !!
