I bought this same rifle about 2 months back, mounted a Nikon 6-18X40mm mildot Buckmaster scope on it and took it to the range. Started at 50 yards and had it zeroed in 5 shots. I was using cheap Winchester Super X 180 grain bullets and the last 3 shots were touching each other. I switched to 200 yards and got a 1" 3 shot group right off the bat, so no complaints there.
Once I got the overall length gauge from Hornady and measured the chamber, I reloaded 50 cartridges with 165 grain Hornady BTSP and 68.5 grains of IMR 4831 with a COAL of 3.36". First trip to the range I shot a 5 shot group at 100 yards that measured .6" If I turn the muzzle brake
off, bullets shift 4" to the right at 100 yards. With the muzzle brake on, the .300 Winchester Magnum shoots with less kick than a 30-06. I can't wait to take it to my uncle's property and test it out to 500 yards when the weather gets warmer. It's a good gun, and I really hope Savage makes it right for you.
