Brake Rotors vs the 50cal...

Published on October 22, 2017
Duration: 12:31

This video from DemolitionRanch tests the penetration capabilities of various firearm calibers against stacked automotive brake rotors. The experiment, led by Matt Carriker, demonstrates that smaller calibers like .22 LR and .45 ACP are largely ineffective, while larger rifle rounds like 5.56mm and .338 Lapua Magnum show significant penetration. The .50 BMG proves capable of penetrating multiple rotors, highlighting its extreme power. The test also explores whether high-velocity impacts can ignite brake cleaner applied to the rotors.

Quick Summary

Automotive brake rotors can act as improvised armor, stopping smaller caliber rounds like .22 LR and .45 ACP. Larger rifle calibers like 5.56mm and .338 Lapua Magnum can penetrate one or more rotors, while the powerful .50 BMG can penetrate multiple stacked rotors.

Frequently Asked Questions

Can brake rotors stop bullets?

Automotive brake rotors can act as improvised armor, stopping smaller caliber rounds like .22 LR and .45 ACP. Larger rifle calibers like 5.56mm and .338 Lapua Magnum can penetrate one or more rotors, while the powerful .50 BMG can penetrate multiple stacked rotors.

What is the most powerful caliber tested against brake rotors?

The most powerful caliber tested was the .50 BMG, fired from a Barrett M107A1. This round demonstrated the ability to penetrate multiple stacked brake rotors, showcasing its extreme power and armor-piercing capabilities.

Did the brake rotor test show any fire or explosion effects?

While brake cleaner was applied to the rotors to test for ignition, the high-velocity impacts did not cause significant fire or explosive effects. A final test with starter fluid was used to create a fire effect, but this was a separate ignition method.

Which firearms were used in the brake rotor ballistics test?

The test featured a variety of firearms including a .22 LR Ruger Mark I, .45 ACP FNX-45 Tactical, .22 Hornet Taurus Raging Hornet, a .44 Magnum Revolver, a 5.56mm AR-15, a .338 Lapua ArmaLite AR-30A1, and a .50 BMG Barrett M107A1.
