Today I went hunting but didn't get anything. So I discharged the crossbow into my target bag as stated in the handbook the. Well I shot at the target and the bowstring jumped the arrow ruined the arrow and shot it about 15yrds intended target was 25-30. I believe I saw some smoke so I got kinda concerned. After evaluating the string I noticed some wear or some burn marks (rails were lubricated ) should I go get a new bowstring put on it?
