Ideal broadhead weight for elk hunting?

May 8, 2026

Quick Answer

Elk hunters typically prefer broadheads weighing between 100-140 grains for optimal penetration and kinetic energy transfer.

Broadhead Weight Considerations

When selecting a broadhead weight for elk hunting, it’s essential to balance penetration with kinetic energy. A heavier broadhead can provide more kinetic energy but may compromise penetration if it exceeds the safe limit for the bow used. A safe starting point for most bows is a 100-120 grain broadhead.

Broadhead Kinetic Energy

For elk hunting, a broadhead with a kinetic energy of 90 ft-lbs or higher is recommended. To achieve this, you’ll need to consider both the broadhead weight and the bow’s kinetic energy output. A general rule of thumb is to use a broadhead that is within 5-10% of the bow’s kinetic energy output. For example, if your bow produces 120 ft-lbs of kinetic energy, a 100-120 grain broadhead would be suitable.

Broadhead Selection Tips

When selecting a broadhead for elk hunting, consider the arrow’s weight, bow’s kinetic energy output, and the terrain where you’ll be hunting. A heavier arrow with a 100-140 grain broadhead may be more suitable for dense forest or mountainous terrain, where penetration is critical. In open terrain or when hunting larger elk, a lighter arrow with a 90-100 grain broadhead may be sufficient. Always test your setup with a broadhead before hunting to ensure reliable performance and penetration.
