Retired neurosurgeon Chriss Mack takes his first Cape buffalo while hunting with Tim Sundles, and it turns into a textbook lesson on why these animals are often called “bulletproof.” Despite taking multiple lethal hits from a .416 Remington, this old bull refused to go down, forcing careful follow-up shots at close range. Tim and the team break down exactly what’s happening inside the animal’s body, why double-lung and heart shots don’t always produce immediate results, and why Cape buffalo are better described as shockproof, not bulletproof. Using real-world analogies and Chris Mack’s medical background, the group explains how the nervous system, blood volume, and sheer mass of these animals allow them to keep fighting long after fatal damage is done, and why hunters can never assume the job is finished until the buffalo is down for good.
