Let's see, you could have a stock stringset (baracuda's) and have less than 200-250 shots on them? IMO baracuda's are poorly made strings and take that long before they stop stretching. Or, you could have a strand broke on your string? Even if you can't see a broken strand there could be one under your serving. If that's the case the it's futile to repair. Lastly, your string could be unbalanced? Too many twists on the part of the string above the center serving and not enough twist in the part below the center serving (or the other way around). In any case save yourself some pain and suffering. Take it to a pro shop if you aren't capable (bow press) and have them put on a quality set of custom strings. $60-70 + installation. Then you can take off that peep tube and shoot with no worries! Well, no worries about string rotation that is.
