Duration: 4:24

This video demonstrates a practical ballistic penetration test comparing the effectiveness of 5.56x45mm (AR-15) and 7.62x39mm (AK-47) ammunition through phone books. Instructor Edwin Sarkissian, an established firearms content creator, provides an enthusiastic analysis of the results, highlighting how bullet weight and velocity influence penetration depth. The experiment reveals surprisingly similar penetration between the two calibers under these specific test conditions.

Quick Summary

In a ballistic test comparing an AK-47 (7.62x39mm, 124gr) and an AR-15 (5.56x45mm, 55gr) using phone books, both calibers demonstrated remarkably similar penetration depths, stopping around the 26th-27th book. The higher velocity of the 5.56mm round appears to have compensated for its lighter bullet weight.

Frequently Asked Questions

How did the 7.62x39mm AK-47 perform against phone books compared to the 5.56x45mm AR-15?

In this specific test conducted by Edwin Sarkissian, the 7.62x39mm AK-47 round (124 grain) showed surprisingly similar penetration to the 5.56x45mm AR-15 round (55 grain), both stopping around the 26th to 27th phone book.

What factors influence bullet penetration in ballistic tests like this?

Bullet penetration is influenced by several factors including caliber, bullet weight, bullet construction (e.g., full metal jacket, hollow point), velocity, and the density and composition of the material being penetrated. In this test, the higher velocity of the 5.56mm round likely compensated for its lighter weight.

What type of ammunition was used in the AK-47 vs AR-15 phone book test?

The AR-15 was fired using 5.56x45mm ammunition, specifically a 55-grain projectile. The AK-47 was fired using 7.62x39mm ammunition, noted as a 124-grain projectile for the test.

Can phone books be used as a reliable medium for ballistic testing?

Phone books can serve as a readily available and relatively consistent medium for demonstrating comparative penetration differences between various ammunition types. However, results should be interpreted cautiously as they don't perfectly replicate tissue or other barriers.
