my bow is loosing brace hieght the more I shoot it?, whats wrong?
Likely, the string is stretching. Is it a fairly new bow? Do you know the string material?
If it's not new like asked by kadbow, then it sounds like the string is going to break pretty soon. Inspect especially your nocking point area and make sure the strands are not allready broken - under the serving.
String stretch. If the string is new then it is no big deal, just twist the string tighter to increase brace height. All new strings stretch as they break in and need to be twisted to increase brace height again. If the string is 9 months to a year old it should be done stretching and I would think you might need to replace it.
Just my opinion,
