I saw this little segment on the Discovery channel on "futureweapons" which dealt with a new sniper rifle and cartridge, the Barrett .416. They didn't give ballistics but said it was designed to remain supersonic to 2500 yards! That's no typo, two thousand-five hundred yards. The show host, who claimed to be a former seal sniper, took one shot at a 36" bull and placed it about six inches below dead center at 2500 yards! In the movie "Sniper II" Tom Beringer claimed to have picked off a Cuban general at a mile and a half but that was a movie and one which took no trouble to get its' guns right. Like when fearless Tom picked up a Mosin-Nagant and proclaimed "Mauser '98, 7.9mm, best rifle the Germans ever built. Then in the next scene he had mounted a scope, altered the bolt and was off on a sniping mission, apparently without having ever fired a shot from his "Mauser".
But what do you all think of a "mile and a half sniper rifle"? Sarah Brady will pee her pants!
