This video provides an in-depth review of the M855 5.56 NATO round, specifically from Lake City. The host, Mrgunsngear, a recognized expert, details its ballistic performance using a chronograph and ballistics gel. Key findings include average velocities, energy levels, and terminal performance characteristics, with a discussion on its effectiveness and limitations compared to other ammunition types for different applications.

Quick Summary

The M855 5.56 NATO round, from Lake City, averages 2917 FPS and 1170 ft/lbs of muzzle energy from a 16-inch barrel. In ballistics gel, it tumbles around 6 inches and fragments, separating its steel penetrator. While not true AP, its terminal performance may be less ideal for home defense than expanding bullets due to potential over-penetration.

Frequently Asked Questions

What is the average velocity and muzzle energy of the M855 5.56 NATO round?

The M855 5.56 NATO round, specifically the Lake City manufacture tested, achieved an average velocity of 2917 FPS and produced 1170 ft/lbs of muzzle energy when fired from a 16-inch barrel. This data was collected using a Shooting Chrony Model F-1 chronograph.

How does the M855 round perform in ballistics gel?

In ballistics gel tests, the M855 bullet began tumbling around 6 inches and exited the first gel block at 14 inches. Fragmentation was observed, with the steel penetrator separating from the copper jacket, which continued onward.

Is the M855 round considered armor-piercing (AP)?

No, the M855 round is not technically classified as armor-piercing (AP) ammunition. While it features a steel penetrator core designed for increased penetration against hard targets, it does not meet the legal definition of AP ammunition.

What are the recommended alternatives to M855 for home defense?

For civilian home defense, experts often recommend ammunition types like soft points or Open Tip Match (OTM) bullets. These are generally designed for more controlled expansion in soft tissue, potentially offering better terminal effects and reduced over-penetration risks compared to M855.
