The Ruger Americans ain't the same rifle as the older model 77 variants. They are butt ugly, but all shoot as good as anything. No experience with the Mossberg, but I've yet to see a Ruger American that wouldn't shoot MOA. Most of the time closer to 1/2 MOA. Two weeks ago I watched my nieces husband shoot a 4" group at 600 yards with a $350 Ruger Predator in 6.5 CM with a $200 scope using $13/box S&B factory loads. I have a Ranch in 5.56 and a Predator in 308. If I needed a 450, my money is on the Ruger.
