I just found out that my bow was given to me from the bow shop three years ago with a draw lenth of 29 1/2". I have been shooting it like this for three years. I have killed one doe with it and shot another, but couldn't find her last year. Last night I went to get a kisser button on my bow to help with my anchor point. The guy helping me tells me the draw length is too long. I get measured and my draw length is 27 1/2". The mistake was made when I bought the bow. They are ordering me new cams and replacing them at no cost. The question is this....Can anyone give me an opinion on what will the affects be on my shooting with a shorter draw length? will this help me out or tighten up my groups???
