Trust me you can get a .50 bullet to fly within 6" of someone.
The force alone of the bullet passing is enough to rip a arm/leg clean off.
Very entertaining to watch then you have the added bonus of watching the little tw@t Scream beg for his life as he bleeds out on the floor.
You could even torment him by emptying a packet of QuickClot out in front of him so it blows away in the breeze.
