Guns vs 1in Thick Steel Armor

Published on December 7, 2015
Duration: 11:17

This video tests the ballistic resistance of a 1-inch thick AR550 steel plate against various calibers. Handgun rounds had minimal effect, while intermediate rifle rounds like 5.56 and 7.62x39 caused minor pitting. Full-power rifle rounds, especially .308 API and .50 BMG variants, significantly impacted the plate, with .50 BMG AP nearly penetrating. The AR550 steel proved exceptionally durable against most tested firearms.

Quick Summary

A 1-inch thick AR550 steel plate was tested against various firearms. Handgun rounds had minimal effect, while 5.56 and 7.62x39 caused pitting. .308 API and .50 BMG rounds caused significant craters, with .50 BMG AP nearly penetrating the full inch of steel, demonstrating the plate's high durability.

Frequently Asked Questions

What is AR550 steel and how does it perform against firearms?

AR550 steel is a high-hardness alloy specifically designed for ballistic protection. In this test, a 1-inch thick plate proved highly resistant, with handguns causing minimal marks and even .50 BMG rounds only causing significant deformation without full penetration.

Can 5.56 or 7.62x39 rounds penetrate 1-inch AR550 steel?

Standard 5.56 and 7.62x39 rounds, including M855 'Green Tip', were tested against 1-inch AR550 steel. They were able to chip small pieces off the surface but did not penetrate the plate.

Which calibers were most effective against the 1-inch AR550 steel plate?

The most effective calibers tested were the .308 Winchester API and various .50 BMG rounds (AP, APIT). These rounds caused significant craters and deformation, with the .50 BMG AP round nearly penetrating the full inch of steel.

Does .50 BMG armor-piercing incendiary ammunition penetrate steel better than standard AP?

In this test against 1-inch AR550 steel, .50 BMG Armor Piercing (AP) rounds came closest to full penetration. While incendiary rounds produced large flashes, they did not necessarily show superior penetration capabilities compared to the AP variants.
