I dont like a 3x9 scope for shots that long. I would rather have a scope like a Nikon buckmaster 4-14x or a Weaver classic 4-16x(which is on my 22-250) or a Bushnell 5-15x 3200. These scopes are all in cheaper price range and seem to be pretty nice.

A 4-12 Leupold rifleman is way over price at 225ish for the quality of that scope. IMO they are no way worth that kind of money.

A few good sites to check out to order a scope are

www.natchezss.com
www.dnrsports.com
or ebay

Natchezz has the 4-14x refurbished Buckmaster for 229. Which is a pretty good deal.
