Leupold Vari-X II scope, 6x36.
Not a bad scope -- the simplicity of the fixed magnification has its virtues, but it's not one I'd choose to put on a .30-30 given the typical role that .30-30s are usually called on to perform.
If it were me, I'd go with a 4x or in some cases something like a 2.5x is even better. The reason is that you normally think of .30-30 lever actions as something you hunt with when the action is fast and the ranges aren't all that long. Thus, field of view becomes critical, and you get a wider field of view at lower magnification. And since you normally aren't talking about taking shots much over 200 yards with a .30-30 anyway, you can get away with the lower magnification. The shorter the max range you are expecting, the lower the magnification you can get away with.
In a nutshell -- the lower the magnification, the wider the field of view, and the wider the field of view, the faster the target acquisition.
