From The UberReview: Homing Bullets Are a Scary Idea

Whoa!! That is just pure craziness!!! o.O

Scientists at Sandia National Laboratories have successfully created a self-guided bullet prototype that is able to home in on a laser-designated target from more than a mile away.

The laser-guided bullet looks more like a small missile or dart than a conventional bullet. Regular bullets are held on course by their spin. The laser-guided bullet uses fins instead, so it doesn’t spin, it flies and its trajectory can be altered via the fins mid-flight.

The magic happens on board the bullet itself. An optical sensor collects information and relays it to an 8-bit central processing unit, which controls the electromagnetic actuators that adjust the fins. According to researchers Red Jones and Brian Kast, the tiny size of the bullet actually makes this feat relatively easy to perform (the bullet is more easily controllable than a cruise missile).

As far as precision goes, there is no comparison. Over a range of half-a-mile, a conventional bullet might be off target by as much as 10 yards. The laser-guided bullet will spread by as much as eight inches.
