It should be noted that firing it is one thing, but you're scored full marks for a hit at those ranges, and you can expect scores of something like one to four hits out of ten at 400 yards in a range situation, where you have an obvious, easily defined (standing) enemy, on a contrasting background, in a predictable location, with a nice firing point to shoot from. It's not quite the same when you're ducking behind a little mound of earth, trying first to locate and then to actually shoot at a bush with muzzle flashes coming out of it.
