i would suggest a leupold rifleman either in 3-9 or 2-7, i think they are around $150-200. i would also suggest the leupold quick release bases and rings so depending on where you're hunting you can remove the scope and use open sights.

ever since i bought my first leupold i'm hooked. i never realized how obvious the difference in scopes is when you're looking through them ...especially in low light conditions.
