Different killing mechanisms.
Killing mechanism between expansion bullet, and sharp broadhead arrow is different.
They kill in different way. Here is best description i found:
Bullets kill primarily through high-energy impact. When a bullet strikes an animal, it crushes tissue and bone due to its kinetic energy. This impact can incapacitate the animal by breaking major bones, which reduces its ability to escape. The energy transfer from the bullet creates a wide wound channel, leading to significant tissue destruction. This mechanism also causes severe bleeding and can induce shock to the nervous system, further contributing to the animal’s incapacity or death.
In contrast, arrows utilize a low-energy impact mechanism. Broadhead-tipped arrows are designed to cut through vital tissues rather than crush them. They function more like knives or swords that slice blood vessels upon penetration. The effectiveness of an arrow relies heavily on proper shot placement; if an arrow is poorly placed, it may not cause immediate incapacitation or significant blood loss, making recovery difficult.
Wound Characteristics
The wounds created by bullets are characterized by both permanent and temporary cavities due to their high speed and mass. Bullets create a larger wound track compared to arrows because they expand upon impact (in the case of expanding bullets) or maintain their shape while causing extensive damage as they pass through tissue.
On the other hand, arrow wounds tend to be narrower but deeper due to their design and sectional density. Arrows penetrate effectively because they are long and skinny, allowing them to travel through flesh with less resistance than a bullet would encounter when trying to penetrate similar material.
In summary, bullets kill through high-energy impact that crushes tissues and causes extensive damage, while arrows kill by cutting vital tissues with low-energy impacts, requiring precise placement for effective results.
