My first thought was to suggest checking the crown, but then remembered a buddy's 300 Savage. Factory loads hit about 6" high at 100 yards. . . we played with bullet weight to get one that matched the sights. Once he found an Ideal tang sight, he had a little more flexibility on loads.
The Ideal tang sight is a pain to find sometimes, the tang sight from Marbles is pretty good. Problem is you can't really lower it below the line of sight of your rear barrel sight. That brings us back to playing with loads, or as Pony Express suggested, getting a higher front sight.
