(53,302 posts)Bullets work by dumping energy into the target and causing it to break up. They kill by dumping enough of it in the right place to break up things you can't survive without. Which is why guys who put their pistols in their waistbands and wind up shooting their dicks off get to go home and explain themselves.
Energy is mass x velocity, whether you're talking about guns or freight trains.
This round takes a 200 grain round traveling 1100 feet per second and converts it into one 100 grain round and three 33 grain pieces traveling the same speed.
The core will dump half the energy into the target. The pieces might not break the skin--wind resistance will slow them down and the drag will probably slow down the core, unless that same wind resistance causes them to break the hair-thin wires holding them together.
In the 1980s the Army wasted a lot of money attempting to make the 5.56mm round more lethal by using flechette rounds, three mini bullets stacked, and all sorts of other shit. The Belgians also wanted to make 5.56 more lethal so they worked on putting a heavier projectile in it. The current NATO 5.56 round has the heavier Belgian projectile. Because one fact has been constant since the beginning of guns: the more a projectile weighs, the more effective it is because you put enough powder behind it to give it energy.
