content: Several of these came with my crossbow so I used them to sight in and bought Gold Tip brand bolts for hunting. They're a bit brittle/ fragile as compared to the Gold Tip bolts. They were destroyed by target shooting, some had the inserts pull out and left the insert and broadhead inside my target and others snapped off when I pulled them out. It seemed to me like just the force of hitting the layered target was enough to crack the arrow or break the glue loose and they finished breaking when I tried to pull them out.
