This video demonstrates the ballistic performance of three different rifle cartridges (5.56 NATO, 6mm ARC, and 8.6 Blackout) against cinder blocks and bricks. The 8.6 Blackout with a 404-grain subsonic REVENANT round, fired from a 1:3 twist barrel, proved exceptionally effective at disintegrating cover. The 5.56 and 6mm ARC showed significantly less penetration and destructive capability against the same barriers.

Quick Summary

The 8.6 Blackout cartridge, featuring a 404-grain Phantom Defense REVENANT subsonic round and a 1:3 twist barrel, demonstrated superior performance against cinder blocks, completely disintegrating them. This highlights its significant barrier penetration capabilities, outperforming 5.56 NATO and 6mm ARC in this ballistic test.

Frequently Asked Questions

Which rifle cartridge is most effective at penetrating cinder blocks?

In this test, the 8.6 Blackout cartridge, specifically with a 404-grain subsonic REVENANT round fired from a 1:3 twist barrel, proved to be the most effective at penetrating and disintegrating cinder blocks, significantly outperforming 5.56 NATO and 6mm ARC.

How do 5.56 NATO and 6mm ARC perform against cover like cinder blocks?

Both 5.56 NATO and 6mm ARC showed limited effectiveness against cinder blocks in this test. While 5.56 could turn blocks into 'Swiss cheese' at closer ranges, and 6mm ARC created a hole, neither demonstrated the destructive power of the 8.6 Blackout against this type of barrier.

What factors influence a bullet's performance against barriers?

Key factors influencing a bullet's performance against barriers include its caliber, weight, construction, velocity, and rotational energy. Barrel length and rifling twist rate also play significant roles in stabilizing the projectile for optimal impact.

Is 8.6 Blackout suitable for situations requiring barrier penetration?

Based on this test, the 8.6 Blackout, particularly with heavy subsonic rounds like the 404gr REVENANT, is exceptionally capable of penetrating and destroying cover like cinder blocks. This suggests it's a strong contender for scenarios where barrier engagement is a consideration.
