I never specified using broadhead tips. Blunt or even field tips would suffice penetrating flesh with a compound bow. And as for making the arrows, which would be easier and supplies readily available? Lead and brass including gun powder, or various pieces of relatively strong and straight wood? I know it would be hard making it precise enough to fly straight, but the relative use of this would be more beneficial than say a rifle and/or handgun. Also the power of the compound bow would making the flying part difficult as well. Just thinking more survival with what you have, than what you don't have.
