Heavy/Standard Arrows
If you are using your crossbow for hunting purposes, you should consider shooting a standard weight or heavyweight arrow. Despite the fact that they will shoot slower, they carry a greater amount of kinetic energy, or penetration power, as compared to a lightweight arrow.
Since maximizing penetration and cutting damage with your crossbow broadhead significantly increases your chances of harvesting an animal, you should shoot a crossbow bolt that has the greatest amount of kinetic energy while still shooting as fast and accurately as possible.
Standard weight and heavyweight crossbow arrows also make your crossbow quieter, since more energy is required to accelerate a heavier arrow, leaving less energy to be dissipated from the crossbow as vibration or “game spooking” noise. Since there is less energy left over, shooting these arrows also means there’s less wear and tear on your hunting crossbow.
