When i bought my last bow i shot it for about a month, then i'm guessing the string finally got stretched out or something because i took it out one day to shoot and i was shooting way off. Well i'm going to buy a new bow tomorrow and i was wondering about how many shots it takes to get a string fully stretched out? And after that will i then have to sight it in again? Also i heard that if you are hunting in the rain and your string gets wet and you dont have wax on it the string will stretch out more...is this true? Thanks
