Definately, you'll get extreme accuracy and deadly game performance at 900 fps. I would learn toward a 350 gr if intending to load primarily at 900 fps. It can still be cranked tup to 1500 fps if you want to get more of a kick out of it, but I think what you are aiming for is the optimum deer gun, yet capable of taking elk cleanly with careful shots.
The only time I fired a 475 was with my 400 LFN's loaded to 1000 fps. A very pleasant and accurate gun to shoot, yet the bullets acted a bit like a buldozer when they hit the backstop. But the WFN is best for game with the low velocities.
