 A typical handgun round, like a 9mm round versus an AR-15 typical round, a handgun round will go clear through you, that sort of pinhole on both sides. But when an AR-15 round typically hits you, it makes that small entry wound, but then inside it creates this shockwave, this blasting pattern that blows out the backside of people, causes internal injuries, and it's just devastating. It makes it very effective for a military weapon, but it's horrific when you see these in civilians.
