AK47 vs AR15: CRAZY Difference In Steel Penetration

Published on October 28, 2022
Duration: 5:07

This guide details a steel penetration test comparing the AR-15 (5.56 NATO) and AK-47 (7.62x39) platforms. The experiment, conducted by Banana Ballistics, utilizes digital calipers to measure penetration depth on mild steel plates at 50 yards. The results indicate that the 5.56 NATO, despite lower energy, achieves greater penetration due to its higher velocity, demonstrating a key difference in steel engagement capabilities. Safety warnings are emphasized throughout the procedure.

Quick Summary

The AR-15 (5.56 NATO) showed greater steel penetration than the AK-47 (7.62x39), reaching 0.395 inches into a 3/8 inch plate versus 0.216 inches. This test, conducted by Banana Ballistics, emphasizes that velocity, not just energy, is key for penetrating mild steel, with precise measurements taken using digital calipers. Safety warnings are paramount for such experiments.

Frequently Asked Questions

What is the primary difference in steel penetration between the AR-15 (5.56 NATO) and AK-47 (7.62x39)?

The AR-15 using 5.56 NATO demonstrated superior steel penetration, reaching 0.395 inches into a 3/8 inch plate, compared to the AK-47's 7.62x39 at 0.216 inches. This highlights velocity's impact over energy for this specific test scenario.

Which ammunition caliber has more energy, 5.56 NATO or 7.62x39?

The 7.62x39 cartridge, specifically the Tulammo load tested (122 gr FMJ), possesses more energy (1568 ft/lbs) than the Winchester 5.56 NATO load (55 gr FMJ) which has 1306 ft/lbs. However, energy doesn't always equate to penetration effectiveness.

What tools are essential for accurately measuring steel penetration in firearm tests?

Digital calipers are essential for accurately measuring the precise depth of penetration into steel plates. This allows for objective comparison of different ammunition types and calibers, as demonstrated in the test comparing 5.56 NATO and 7.62x39 rounds.

What safety precautions should be taken when testing firearm penetration on steel targets?

It is crucial to understand that shooting steel can be dangerous due to ricochets and fragmentation. Always wear appropriate Personal Protective Equipment (PPE), including eye and ear protection, and never attempt such tests without proper training and a controlled environment.
