I don't think it's draw length because I had the latest bow fit to my draw length. I should have been more specific in my original post. I am shooting consistantly low at all the yardages by about 2". I am just wondering if that's normal string stretch. It's happened to the last 3 bows I have owned and once I adjust the pins, I am dead on for the rest of the summer. I wouldn't think my form would change every year. The latest bow is a Hoyt AlphaMax and I just thought I would get more life out of the string. I do shoot it a lot, so maybe it's time for a new string. Spring bear season is coming up, so maybe I need to take it to the bow shop and have it tuned and have the string looked at.
