Full Auto Rifle Rounds vs 8 Layers of Pistol Armor

From DemolitionRanch:

Let’s shoot some rifle rounds through pistol armor, Level IIIa, and see how many panels it takes to stop them! This armor is NOT made to stop rifle rounds, it is rated to stop up to .357Sig and .44mag pistol rounds. I am amazed by how much these cloth panels will deform metal bullets.

As a side note, some people think that silencers/suppressors slow the bullet down, but with a good suppressor, they actually speed them up a little bit, improving penetration.
