AK-47 VS AR-15 VS PHONE BOOKS - 7.62 VS 5.56

Duration: 4:24

This video compares the ballistic penetration of 5.56mm from an AR-15 against 7.62x39mm from an AK-47 using phone books as a medium. Despite the 7.62x39mm having a heavier bullet (124gr vs 55gr), the 5.56mm round achieved slightly deeper penetration, reaching 27 books compared to the 7.62x39mm's 26-27 books. The experiment suggests that the higher velocity of the 5.56mm round may have compensated for its lighter weight in this specific test.

Quick Summary

The 5.56mm round from an AR-15 penetrated 27 phone books, while the 7.62x39mm from an AK-47 penetrated 26-27 books. The higher velocity of the 5.56mm likely equalized penetration depth despite the 7.62x39mm's heavier bullet.

Frequently Asked Questions

How did the AR-15's 5.56mm round perform in the phone book penetration test?

In the test, a 55-grain 5.56mm round fired from an AR-15 penetrated 27 phone books. An initial shot veered off, exiting around the 19th book, but a second, more centered shot achieved deeper penetration.

What was the penetration depth of the AK-47's 7.62x39mm round?

The 124-grain 7.62x39mm round fired from an AK-47 penetrated approximately 26 to 27 phone books. This showed a surprisingly similar penetration depth to the 5.56mm round used in the AR-15.

Why did the 5.56mm and 7.62x39mm rounds have similar penetration depths?

Despite the 7.62x39mm having a significantly heavier bullet, the 5.56mm round's higher velocity likely compensated for its lighter weight, resulting in comparable penetration depths in the phone book test.

What was the primary comparison made in the video?

The video primarily compared the ballistic penetration capabilities of the 5.56x45mm cartridge (AR-15) versus the 7.62x39mm cartridge (AK-47) using phone books as a penetration medium.
