Was looking at my string on my 380 today to see if I could see which way it was twisted which I see I did go the right way (got lucky). But anyway I noticed my string was touching the left rubber bumper. Now I have not shot my bow in a week and wen I put it away it still had a good 1/4 off the rubber. I have shot my bow maybe 5--60 times. My question is how long does it take the stock string to stretch I figured by now it would have stretched out. Second why is it only touching the left bomber and not both equal?
