Happy Pappy something is hitting or very loose on yer CB. Bring yer string back close to high brace line.Make sure its not getting to hit the riser. You have trimmed plastic limb spacers. Sometimes those arrows get off, like they said use one and same one so you can see whats going on. Both limbs are snug with their limb bolts? The riser is snug in place and not moving from side to side at each shot ?
