Thats a great idea Straightarrow. I am going to do that. I have adjusted my rest so it is hitting in the same location, and I did a little group shooting and they are gouping just as tight as before. I think that is what you mean by group tuning? But I still have a couple of ? about tuning a bow. First what does that actually mean and How do you know its out of tune? Is their a book or video you can get to help you step by step go through the tuning process? And what do all of you do to tune your bow. what steps do you take? Paper tune? Bare shaft? Fletched shat? what distances? I guess the big ? is how do you know its out of tune?
