This video compares the M16 (chambered in 5.56x45mm NATO) and the AK-74 (chambered in 5.45x39mm) through various ballistic tests. The AK-74's 5.45x39mm round demonstrated superior penetration in pumpkins and paper stacks, while both rounds easily penetrated car doors. Terminal ballistics differed, with the 5.56 fragmenting more readily than the 5.45.

Quick Summary

In ballistic tests comparing the M16 (5.56mm) and AK-74 (5.45mm), the 5.45mm round showed superior penetration through pumpkins and paper stacks. Both rounds penetrated car doors easily. Terminal ballistics differed, with the 5.56mm fragmenting more than the 5.45mm.

Frequently Asked Questions

Which rifle caliber, 5.56mm or 5.45mm, demonstrated better penetration in ballistic tests?

In tests involving pumpkins and paper stacks, the 5.45x39mm round from the AK-74 consistently showed superior penetration compared to the 5.56x45mm NATO round from the M16. Both rounds, however, easily penetrated stacked car doors.

How did the M16 and AK-74 compare in terms of recoil?

The video noted that the AK-74 exhibited noticeably less recoil than a standard AK-47. While a direct comparison to the M16's recoil wasn't detailed, the AK-74's reduced recoil was highlighted as beneficial for follow-up shot accuracy.

What were the key differences in terminal ballistics between the 5.56mm and 5.45mm rounds?

During a water bottle test, the 5.56mm round fragmented completely into small pieces of lead and jacket. In contrast, the 5.45mm round remained largely intact after impact, indicating different fragmentation and energy transfer characteristics.

What is the historical context for the 5.45x39mm cartridge?

The 5.45x39mm cartridge was developed by the Soviet Union specifically to compete with the Western 5.56x45mm NATO round. Its design aimed for better long-distance performance and penetration compared to the older 7.62x39mm cartridge used in the AK-47.
