I'm sure you'll like it...
It will be a much better balanced rig on a 30-30 than any 3x9 and will improve the handling qualities of your rifle..
You will be amazed at what a fast and efficient sighting system it is for hunting in the woods..
Variable scopes and high magnification are HIGHLY overrated on hunting rifles..
Many of us would be much better served with a quality fixed power scope of 4x or less than the big, heavy, high power variables that I see on most hunting rifles...
