there are zero intermediate cartridges from anywhere in the world coming from any barrel length that can get through our lvl4 plates. they can literally stop a .50bmg round even though the deformation becomes deadly. either way though it doesn't matter when you're getting lit up in close quarters, getting hit by fragmentation or taking a stray bullet to the 80% of your body that isn't covered by a ceramic insert. it does help but people overestimate the relevance of a chest plate.  not even tungsten core 30-06 point blank goes through a lvl4 plate
