A breakthrough in precision bullet technology for small caliber firearms will make striking a target an easier task. Two researchers at Sandia's National Laboratories created a self-guided dart-like bullet able to strike a target more than a mile away.
The self-guided 4-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.
