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