how many hard hats it takes to stop an Arrow ?
This experiment tests the penetration power of arrows against hard hats. A PSE Evoke 31 compound bow, drawing 75 lbs and shooting at 330 fps, was used. A standard practice tip arrow penetrated two hard hats, stopping at the third. A stainless steel broadhead arrow, however, completely pierced three hard hats, demonstrating significantly higher penetration capability.
