Stats

In-game description

A .366 TKM (9.55x39mm) AP-M cartridge loaded with an 16 gram armor-piercing bullet from a 9x39mm SP-6 gs cartridge, composed of a hardened carbon steel core with a two-layer semi-jacket, a lead interior and a bimetallic exterior, in a modified steel case. This ingeniously improvised cartridge was created by Mechanic due to the precarious situation of its customers in Tarkov, resulting in a cartridge that can pierce through basic and intermediate ballistic body protection, as well as providing a considerable stopping power effect, however, its own design alters its flight pattern, making it less accurate. Its design also allows it to be used in 7.62x39mm AK magazines without any problem.

Against which armor

Penetration 42 is above the resistance of class 4 armor (40) — while such armor is intact, the round penetrates it more often than not. Against class 5, penetrations are rare until the armor is worn down.

For example, the vests it can defeat: 6B23-2 body armor (Mountain Flora), Interceptor OTV body armor (UCP), 6B13 assault armor (Flora). The full table is in the armor classes guide.
