This is my first time on this forum and today I purchased my first compound bow. I used a recurve growing up. It is a High Country Excalibur, 65-80# carbon/graphite, already set up. It is a used bow and I like everything about it except the draw length is a little long. After looking at quite a few used bows the last few weeks, and depending on the bow, a 28" or 29" draw is what I need (my actual draw is 28 1/2"). This bow is 30". According to the sticker on it, it is adjustable either 26-30" or 29-33". The 30" is circled on the 26-30" line. The string is in excellent condition as is the bow. I know how to loosen the cable and string without causing damage to the bow. Can I adjust the draw length without replacing the string with a shorter one and how? Any advise is appreciated.
