I just bought a Savage 111FCNS 30-06 and mounted a Leupold Mark 4 LRT 3.5-14x50 scope on it using Warne Maxima rings and base. How far out can I reasonably expect to be able to shoot sub-MOA groups once I find the best matched cartridge set up? I'm hoping for at least 500 yards, preferably further. Lastly, any recommendations on upgrades to the rifle for better accuracy? This is my first Savage and I bought it mainly based on the recommendations of other shooters and information on this forum.
