Use Cement As Cover? (50 BMG Tested)

Published on March 15, 2025
Duration: 1:01

This video tests the ballistic resistance of cinder blocks against various calibers, from .22LR to .50 BMG. It demonstrates that while smaller calibers cause superficial damage, larger rounds like .308 and .50 BMG can significantly compromise or destroy the blocks, highlighting the limitations of cement as ballistic cover against powerful firearms.

Quick Summary

Cinder blocks offer limited ballistic protection, stopping smaller handgun rounds like 9mm with superficial damage. However, powerful rifle calibers such as .308 can cut them in half, and .50 BMG can vaporize them, making cement an unreliable form of cover against high-powered threats.

Frequently Asked Questions

Can cinder blocks stop bullets?

Cinder blocks offer some resistance to smaller handgun calibers like .380 Auto and 9mm, causing superficial damage but no penetration. However, larger rifle calibers such as .308 and especially .50 BMG can significantly damage, cut in half, or even vaporize cinder blocks, rendering them ineffective as cover.

What caliber is most effective against cinder blocks?

Based on the tests, larger rifle calibers are significantly more effective against cinder blocks. The .308 caliber was shown to cut a block in half, while the .50 BMG round completely vaporized two blocks, demonstrating its overwhelming power compared to smaller pistol or rifle rounds.

Is cement a reliable form of ballistic cover?

While cement and cinder blocks can stop low-power handgun rounds, they are not reliable ballistic cover against high-powered rifle fire. Rounds like .308 and .50 BMG can easily penetrate or destroy them, making them a poor choice for protection in scenarios involving rifle threats.

Which firearms were used in the cinder block ballistic test?

The video tested various firearms including the Brea 1301 Tactical, a Glock 19 (.380 Auto), a Kimber Carbon Compact (9mm), a Zastava AK (.223), a Sentry Arms CA3 (.308), and an Ultra Affordable Raptor 50 (.50 BMG).
