Cast Iron's Got Penetration: A Bullet Comparison You Won't Believe

We’ve all seen the videos of people shooting things – watermelons, cars, pumpkins. But this one takes a different, surprisingly insightful approach. Instead of a target that readily absorbs impact, we’re seeing rounds fired into a cast iron skillet. Why? Because cast iron offers a predictable density and resistance. It's a simple, brutal way to visualize projectile penetration.

The test itself is straightforward. The creator pits 9mm (full metal jacket – FMJ) and .45 ACP rounds (including a hollow point) against a cast iron skillet. The result is a visual demonstration of how different calibers and bullet types transfer energy. It's a visceral reminder that 'stopping power' isn't just a marketing term; it's a measurable phenomenon.

Let’s unpack what we’re seeing. The 9mm FMJ round punches through the skillet with noticeable force, leaving a clean, relatively consistent hole. The .45 ACP, especially the hollow point, demonstrates even greater penetration. The hollow point's design, intended to expand upon impact on a soft target, still manages to deliver a significant punch through the dense cast iron. This isn't about maximizing expansion; it's about the raw kinetic energy propelling the bullet forward.

This experiment highlights a few key points for those of us who understand the fundamentals of ballistics. First, caliber isn't everything. Bullet design, weight, and velocity all play crucial roles. Second, material density matters. Cast iron’s resistance provides a baseline for understanding how a bullet performs against different mediums. You're not just seeing a hole; you're seeing a quantifiable measure of energy transfer.

For those of us who reload, this kind of visual data can be surprisingly useful. It reinforces the importance of choosing the right bullet weight and powder charge for a specific application. Even a simple test like this can spark ideas for optimizing your own handloads for maximum penetration – whether you’re hunting, target shooting, or prepping for scenarios where reliable penetration is critical.

Beyond the technical aspects, this video serves as a simple reminder of the power we wield. It’s a power that demands respect, responsibility, and a commitment to understanding the tools we use. And, frankly, it’s just plain cool to see a .45 ACP round punch through cast iron.
