In a lot of ways it would take a lot of the fun out of long range shooting but I’d still buy a few rounds if I could get them “cheap”. I’m sure even as mil-surplus they would be expensive enough I wouldn’t be shooting a lot of these:
Darpa, the Defense Department’s far-out research arm, announced a pair of contracts yesterday, to start designing a super, .50-caliber sniper rifle that fires guided bullets. Lockheed Martin recieved $12.3 million for the “EXACTO” (EXtreme ACcuracy Tasked Ordnance) project, while Teledyne Scientific & Imaging, LLC got another $9.5 million.
If the system works, it’ll “provide a dramatic new capability to the U.S. military,” Darpa says. “The use of an actively controlled bullet will make it possible to counter environmental effects such as crosswinds and air density, and prosecute both stationary and moving targets while enhancing shooter covertness. This capability would have the further benefit of providing increased accuracy and range while reducing training requirements.”
And from the same article:
The agency has earmarked $7.5 million for a laser-guided bullet program. Darpa gave Lockheed $2 million for advanced sniper scopes that could boost kill rates by tenfold, or more. If the system works out as planned, it would actually allow snipers to remain virtually invisible, lost in the “heat haze” in between them and their targets. Our own David Hamling called the project the “next war’s secret weapon.”
