How Bulletproof is Kinetic Sand?

This video from Kentucky Ballistics tests the bullet resistance of a 22-pound steel mug against a wide array of firearms, from .22LR to .577 Tyrannosaur and .50 BMG. The presenter, Scott, systematically fires each caliber at the mug, documenting the impact and penetration. While smaller calibers like .22LR and 5.7mm had no effect, larger handgun rounds like .44 Magnum and .460 S&W Magnum began to dent and deform the mug. Rifle calibers, particularly the 5.56mm and 277 Fury, caused significant damage and penetration. The most powerful rounds, the .500 Nitro Express, .577 Tyrannosaur, and .50 BMG, all inflicted substantial damage, with the .577 Tyrannosaur and .50 BMG penetrating the mug, though neither fully passed through. The test highlights the impressive durability of the heavy steel mug.

This video tests the ballistic resistance of a Dr. Pepper vending machine against various firearms, from .22LR to .50 BMG. The machine demonstrated significant resistance to smaller calibers, stopping rounds like 9mm and .45 ACP. However, larger calibers, including the .44 Magnum, .308 Winchester, and ultimately the .50 BMG, penetrated the machine, with the .50 BMG completely destroying it and passing through. The test highlights that while a vending machine can offer some protection against smaller threats, it is not a reliable ballistic shield against more powerful firearms.

This video tests the ballistic resistance of a large, homemade rubber band ball against various firearms, ranging from .22LR to .50 BMG. The ball, weighing over 20 lbs and composed of approximately 10,000 rubber bands, demonstrates surprising durability, stopping numerous handgun and rifle rounds. The experiment highlights the energy-absorbing properties of the rubber bands, with only the .30-06 Springfield and .50 BMG rounds eventually penetrating the dense mass.

This video tests the penetration capabilities of various firearms against a stack of hockey pucks. It demonstrates how different calibers and firearm types, from .22 LR to .50 BMG, interact with the pucks, showing varying degrees of penetration and puck destruction. The experiment highlights the significant differences in stopping power and projectile energy across a wide range of common and powerful ammunition types.

This video tests the penetration capabilities of various firearms and calibers through watermelons, providing a visual demonstration of bullet energy and destructiveness. The experiment progresses from smaller handgun rounds like the .22 LR up to powerful rifle calibers and a .50 AE Desert Eagle, highlighting how different ammunition types interact with organic material. The .44 Magnum emerged as a surprising leader in penetration among handguns, while rifle rounds often veered off course due to the inconsistent medium.

This video from Yee Yee Life tests the penetration capabilities of various firearms against drywall, ranging from a .22LR to a .50 BMG. The host, Parker, demonstrates how many sheets of drywall each caliber can penetrate, providing a visual comparison of their stopping power in a simulated home environment. The experiment highlights significant differences in projectile energy and effectiveness across calibers.

This video demonstrates the ballistic resistance of an excavator bucket against various firearm calibers, from .22 LR to .50 BMG API. The test, conducted by an experienced individual, shows that while smaller calibers cause minimal damage, larger rounds like the .50 BMG API can penetrate the bucket. The footage provides visual evidence of impact effects and the destructive potential of different ammunition types.

This video tests the penetration capabilities of various calibers against a large pine tree, culminating with a .50 BMG API round. Surprisingly, even powerful rifle rounds like 5.56mm and 7.62mm, as well as handgun rounds like 10mm and .44 Magnum, failed to fully penetrate the tree. The .50 BMG API round, while charring the entry point, also did not exit the back of the tree, demonstrating the significant stopping power of a substantial tree trunk.

This video from Yee Yee Life features an experienced host testing the ballistic penetration of various calibers, from .22 LR to .50 BMG, in an Intex swimming pool. The host demonstrates proper firearm safety and provides detailed measurements of bullet penetration depths, offering unique insights into how different rounds interact with water as a medium. The results highlight significant variations in penetration based on caliber and velocity.

This video tests the ballistic resistance of a Secret Service Suburban window against various calibers, from .22 LR to .50 BMG. While smaller calibers and even a 10mm and .44 Magnum were stopped with varying degrees of damage, the window was eventually penetrated by a .50 BMG sniper rifle round. The testing provides a clear demonstration of the limits of armored vehicle glass against high-powered rifle threats.
