A 6.5# rifle chambered in 308? Yikes. My shoulder hurts just thinking about it. I can see it would be a great hunting gun though.
I just watched MagPuls "The Art of the Precesion Rifle". They had a short barreled 308 as one of the 4 rifles they were shooting. On the video you watch them take 1,000 and 1,200 meter head shots... with ease! The finally was a 1 MILE shot with the 308!! Actually all four of the shooters/rifles made the 1 mile shot. Very interesting DVD... learned a lot that I can't wait to take to the range with my 260 Remington.
