Good advice above, if you haven' t got a release get one! It makes the release the same everytime. I would also suggest having a string loop installedd, it does make a difference and reduces noise and wear on the string. 6' groups at 20 isn' t hunting ready IMO, b/c you can be assured it will grow under the pressure of live animals. Try and strive for 3-4" before you hunt a rule is double your group size on game and if your in the ball game you should be considered ready at that distance(6-8" on deer is the vitals). Also it is good to practice from up if you plan to use a stand, however the result of shooting high isn' t due to elevation but rather improper form when in a tree. Try and bend at the waist not the arm(shoulder to your target) by doing this you will not increase the draw length(which results in shooting high). I practice and hunt mostly on the ground however I do bear hunt in a stand and my POI doesn' t change one bit from the ground to my stands which are 15 feet up, it is all technique and takes practice. If you hunt in a tree stand always wear a safety belt!!!

Other things to consider. Make sure the arrows you have are the correct spine for your setup. Try different arrow and head combination, make sure your bow is tuned to these combinations & properly spined. An untuned bow will cause many erratic problems and tight groups are less achieveable, you can take it to a proshop, have a buddy who knows his stuff help or do it yourself. Do a little research on Easton Arrows website, it is under tuning guide(which talks about spine, flight problems, tuning and solutions). Have somebody who is a knowledgeable bow shooter watch you for form and help you achieve the same anchor, release and follow through each time...this is something that will make you a better shot. You need to get the proper form and get to that point everytime it will result in good groups, confidence and success. Most bow shooters have check or reference points that ensure this happens each time they draw the bow, this not something that can be described but rather you' ll teach yourself(and everybody has different ways/checks). If you don' t have a peep sight installed, get one(acts like a rear sight on a gun) and when starting out is a very good piece of equipment to have. You can also add stabilizer to help steady and weight the bow properly, any proshop should be able to help you with this task. Make sure the draw weight and length match you. Draw length & fit is very important to technique and grouping. Also make sure the poundage you are set at is not too much, this can also result in wandering shots. Pulling a bow uses muscles that you never knew you had and over time you can increase poundage as you gain muscle and endurance power. A bow set at 50 lbs shooting tight groups is a much better option than 70lbs and all over the map.

Lastly keep practicing!
