You may wish to consider a second hand rifle from a local sporting goods store. I have nothing against mossberg, as they do have dependable shotguns, but I have no knowledge of their rifles.
I have hunted with a very dependable 303 british for years, and it only cost me $150.00 big ones. I also bought a 30.06 savage, bolt action, brand new at walmart, with a 3x9 bushnell scope, for $349.00, which is a good rifle, if you can handle the recoil.
Just a little something extra to think about.
