Ive seen naval radar guided guns used on frigates that can move fast enough to shoot down incoming anti-shipping missiles, so thats probrably what you mean
Thisguy one of the best with a pistol (at least here in the US where we shoot pistols larger than .32 caliber (namely .45 caliber) in competition). I've met him myself and he's quite the machine.
That first video was just rediculous. When it's something that you've not really watched before, it makes it almost unbelievable at first. Just crazy...
