Duration: 21:07

This video delves into the evolution and future of the 5.56mm cartridge, comparing historical rounds like M193 and M855 with modern and experimental options like M855A1 and Black Arc's 80.5gr OTM. Ballistic gel tests reveal significant differences in terminal performance, with heavier, specialized rounds like the Sierra Matchking and Black Arc Elite demonstrating superior energy transfer and expansion. The analysis concludes that while 5.56mm has limitations, its effectiveness is highly dependent on the specific ammunition used and its role in military 'fire and movement' tactics.

Quick Summary

The M855A1, an upgraded 62-grain 5.56mm round, offers significantly improved terminal ballistics over the standard M855 'Green Tip'. Testing shows better expansion and energy transfer in ballistic gel, addressing common criticisms of the older round's performance on soft targets.

Frequently Asked Questions

What are the key differences between M855 and M855A1 5.56mm ammunition?

The M855 'Green Tip' is a 62-grain penetrator known for barrier performance but often lacking in soft tissue terminal ballistics. The M855A1 is an upgraded 62-grain round with higher pressure and a steel penetrator, offering significantly improved expansion and energy dump in ballistic gel tests.

Which 5.56mm rounds performed best in ballistic gel tests in the video?

The heavier Open Tip Match (OTM) rounds showed the best terminal performance. Specifically, the 77-grain Sierra Matchking and the 80.5-grain Black Arc Elite OTM demonstrated superior expansion and energy transfer compared to standard military ball rounds.

Why does the military continue to use the 5.56mm cartridge?

The military favors 5.56mm for its role in 'fire and movement' tactics. Its lightweight nature allows soldiers to carry more ammunition and facilitates rapid, high-volume fire for suppression and maneuverability, which are critical in modern combat scenarios.

What is the main criticism of the M855 'Green Tip' 5.56mm round?

The primary complaint regarding the M855 'Green Tip' centers on its terminal ballistics. While designed to penetrate barriers, it often passes through soft tissue without tumbling effectively, leading to reduced wound channels and less reliable incapacitation compared to other ammunition types.
