The Army's New Ammo Is a Long Distance Devastator - M855A1 Gel Test

Published on March 5, 2018
Duration: 4:42

This test evaluates the M855A1 EPR round's terminal ballistics at reduced velocity (1,988 FPS) using a 10.5-inch barrel. Despite the lower speed, the round demonstrated significant fragmentation and a substantial temporary cavity in ballistic gel, penetrating 16.3 inches. This velocity is equivalent to a standard 14.5-inch barrel shot at 350 meters, highlighting the round's effectiveness against tissue and barriers.

Quick Summary

The M855A1 EPR round was tested at 1,988 FPS from a 10.5-inch barrel, achieving 16.3 inches of penetration in ballistic gel with significant fragmentation. This velocity is comparable to a 14.5-inch barrel shot at 350 meters, showing effectiveness against tissue and barriers like Level III steel.

Frequently Asked Questions

What was the test setup for the M855A1 gel test?

The M855A1 EPR round was tested at a reduced velocity of 1,988 FPS using a 10.5-inch barrel and a reduced charge of 21.5 grains of RL15 powder to assess its fragmentation capabilities.

How deep did the M855A1 penetrate the ballistic gel?

The M855A1 round penetrated 16.3 inches into the ballistic gel, exhibiting significant fragmentation and creating a large temporary cavity with minimal 'neck' before breaking apart.

What is the significance of the 1,988 FPS velocity for the M855A1?

This velocity is equivalent to the impact speed of an M855A1 round fired from a standard 14.5-inch barrel at approximately 350 meters, demonstrating its effectiveness at range.

Does the M855A1 perform well against barriers?

Yes, the M855A1 EPR demonstrates impressive performance against intermediate barriers, including Level III steel armor, even at reduced velocities.
