458 Socom vs Body Armor

Published on December 2, 2016
Duration: 10:03

This video details an experimental test by Matt Carriker of Demolition Ranch, assessing the effectiveness of .458 SOCOM ammunition against AR500 Armor Level 3+ steel plates. The test reveals that while individual rounds may not penetrate, the cumulative kinetic energy of multiple .458 SOCOM impacts can eventually cause the steel plate to shatter. The experiment highlights the limitations of body armor against sustained high-energy rifle calibers.

Quick Summary

.458 SOCOM ammunition, particularly heavier 300-grain ballistic tips and solid brass rounds, was tested against AR500 Level 3+ steel body armor. While individual rounds didn't penetrate, the cumulative kinetic energy from approximately 50 impacts eventually caused the steel plate to shatter, demonstrating armor limitations against sustained high-energy rifle fire.

Frequently Asked Questions

Can .458 SOCOM penetrate AR500 Level 3+ steel body armor?

While individual .458 SOCOM rounds may not penetrate AR500 Level 3+ steel armor, the cumulative kinetic energy from multiple impacts can eventually cause the steel plate to shatter and fail, as demonstrated in tests by Demolition Ranch.

What type of ammunition was tested against the body armor?

The test involved PolyCase ARX rounds, known for fragmentation, and heavier 300-grain ballistic tip and solid brass .458 SOCOM rounds. The lighter ARX rounds stripped coating but didn't significantly damage the plate, while the heavier rounds contributed to its eventual fracture.

How does cumulative impact affect body armor?

Cumulative impacts can significantly degrade body armor. Even if individual rounds are stopped, repeated high-energy strikes can cause structural fatigue, leading to fracturing or failure of the armor plate over time, as seen with the AR500 steel plate tested against .458 SOCOM.

What is the significance of the .458 SOCOM cartridge in ballistic testing?

.458 SOCOM is a high-energy rifle cartridge known for its large diameter and significant kinetic energy. Its testing against body armor demonstrates the challenges high-power rounds pose, highlighting that armor effectiveness is not absolute and can be overcome by sustained, high-energy impacts.
