@cmdc: I have a ruger 77 RSI, chambered for .250 savage, and like hodaka's choice of optics, I have a leupold 2.5-8 on it. It works fine and looks fine.
I also have a Ruger 1-A chambered for 7x57, and it has a burris compact 3x9 and the scope conforms well with the trim lines of the rifle. I used the 1-A, 7x57mm for mule deer, and always felt a little overglassed. I think paulB has the right idea, and if I had it to do over I would choose a 2x7.
A scope that I would look at closely for your rifle would be a leupold VX2 ultralight, variable 2 to 7X (under 10 inches and smaller objective). If you want to spend a little less money, burris makes a smaller "timberline" version which is variable 3X to 9X. However, my choice would still be the leupold ultralight.
