Rail guns ...... Phft....
Happy news for you: on one range I frequent, the 800-meter targets are two-foot long sections of railroad rail. painted orange and hanging from a short section of chain. And at least twice I've let fly at them with an M82A1/ M107A1, which punches right through if it hits on the bottom web of the rail. IS a rail gun....You have to have on to be with it in this Twenty-First Century....
