Nice trick if you can do it

Rico says his friend Kelley forwards this:

A breakthrough in precision bullet technology for small caliber firearms will make striking a target an easier task. Two researchers at the Sandia National Laboratories created a self-guided dart-like bullet able to strike a target more than a mile away.
The self-guided four-inch bullet prototype has been successfully tested in both computer simulations and field testing, where bullet speeds have reached 2,400 feet per second. The bullet differs from missile technology, in that the self-guided bullet has an optical sensor that can detect a laser beam on a target, which allows the bullet to steer toward a target.
In one field test, researchers attached a tiny light-emitting diode to the bullet to tract its path and researchers found the "battery and electronics could survive the bullet's launch", the Sandia Lab reported.
The bullet is still a prototype but, if it passes further testing conducted by a private firm, the bullet will be accessible to recreational shooters, law enforcement, and the military. Lockheed Martin assisted Sandia Lab's research and has worked with the military to develop a self-guided bullet over the years.
"While engineering issues remain, we’re confident in our science base and we’re confident the engineering-technology base is there to solve the problems,” Sandia researcher Red Jones said

Rico says he doesn't know how small they can make it, but there are damn few 'recreational shooters' capable of firing a 'four-inch-bullet'...
