Others are welcome to their choices and opinions but I believe you should look long and hard at leupold. They have some crazy high priced scopes way out of your price range but if you look at their whole line at one of the discount dealers I think you can get a great scope (as opposed to some of the other brand good scopes). Leupold is where it is at for QUALITY.
Folks tend to get all wrapped up with power and bells and whistles but if you sit down and really think hard about how you intend to use this scope and rifle you might surprise yourself. Clarity and brightness of a quality scope will help your shooting far better than higher power in a lower quality scope. Lower power scopes will generally be cheeper,regular adjustment instead of "target" knobs will be cheeper,fixed power will be cheeper than variable power.
I have found the leupold "rifleman" line to be a great value when I couldn't justify spending higher $'s
Shop hard ,different places I have bought from were midway (I get a C&R discount) SWFA,Midsouth,Opticplanet. When compareing prices pay attention ,some ship free,some for normal rates,and some "discount houses" give you a great price but then stick you with high S&H . I always start my search at the joint I bought from last but the best deals tend to cycle around.
Leupold has great quality and a rep for standing behind their product.
