i would stick with a 3-9x40 for that close of distance. i would also go with the burris fullfield on scopes if you are not wanting to spend alot. they are real nice and theyhave a ballistic plex reticle which compensates bullet drop from 100 to 500 yards. sorta like a milddot scope and they only range about 160 in price.they do make this scope in higher powers as well for not much more money if you decide to go that rout. good luck
