Full Metal Jacket Ammo
The original intention of the 5.45x39 round was a full metal jacket cartridge capable of penetrating light body armor as well as thin barriers. To do so the Soviet round has a full metal jacket (FMJ) over an internal steel core with a lead inlay. The cavity of the round is hollow, but designed not to deform or expand on impact with soft tissue. The 5.45x39 ammo is capable of reaching velocities of 2,900 feet per second. This blistering, but lightweight cartridge allows for a massive amount of penetration against soft flesh.
