If you want a longer range rifle (out to 400 yards) buy an American sporting rifle. They come ready to mount a scope (or buy used w/scope). A scope makes 400 yards shots much more practical. While you can mount a scope on a mosin, it is a rather poor set-up. A Mauser that has a turned down bolt and is already drilled and tapped can be found but it is just easier to buy American. Often you can get one with scope for well under $400 used or just slightly more new.
