I bought a PSE Nova had it set to 29 1/2" draw at 60#. Sighted it in at 20,30,40,and 50 yards for my pins. I have shot about 125 arrows through it. I am noticing that I am now shooting about 12" lower to hit the middle of the target. Someone told me that my bow string would strecth. Is this true?? If so when will it stop??
P.S. I am positive my sites did not get moved, and am having no problems left or right.
