Duration: 6:14

This video tests the penetration capabilities of various common firearm calibers through a substantial block of aluminum foil. The experiment demonstrates that standard Full Metal Jacket (FMJ) rounds from a .22LR and a 9mm can be stopped by a significant number of aluminum foil sheets, while a 5.56mm steel core penetrator round can pass through a large quantity.

Quick Summary

In a bullet penetration test, a block of 1440 folded aluminum foil sheets successfully stopped .22LR, 9mm FMJ, and 5.56mm FMJ rounds. However, a 5.56mm steel core penetrator round was able to pass completely through the foil block.

Frequently Asked Questions

What caliber of ammunition was stopped by aluminum foil in the test?

The .22 Long Rifle, 9mm 115-grain Full Metal Jacket, and 5.56mm 55-grain Full Metal Jacket rounds were all stopped by the aluminum foil block. The .22LR penetrated approximately 240 sheets.

Did any ammunition penetrate the aluminum foil block completely?

Yes, the 5.56mm XM855 steel core penetrator round was able to pass straight through the entire block of 1440 sheets of aluminum foil during the test.

What was the setup for the aluminum foil bullet penetration test?

The test involved a meticulously folded block of 1440 sheets of aluminum foil, which was then subjected to live fire from various common firearm calibers to observe penetration.

How does a steel core penetrator round differ in performance against aluminum foil compared to FMJ rounds?

Steel core penetrator rounds, like the 5.56mm XM855 tested, demonstrated the ability to pass through a large quantity of aluminum foil, whereas FMJ rounds of similar caliber were stopped. The penetrator also left a cleaner entry hole.
