if you're not sure whether your mechanical broadheads are barbed or not,shoot one into a bag target and try to pull it out.if it slips back out easily with the blades all folded back to the closed position,it's not barbed.if it won't pull back out,and sticks in the bag like a fish hook with it's blades remaining in an open configuration,you've got yourself a "barbed" broadhead!.now imagine that broadhead stuck in a deer not mortally hit and you'll have a clearer picture of the thought proccess behind the law.deer are very capable of removing an arrow with their mouth or by rubbing against trees,but not if it's barbed!.PROTECT OUR SPORT, OBEY ALL GAME LAWS!!.
