A good quality 2.5x or 4x scope is all you'll ever need on a 30-30. If you're so far away a 4x scope ain't enough,you're too far away to shoot it with 30-30 in 1st place.
I know a few people that think like this but I myself like to be able to zoom in to 9 power even if something is only 100-150 yards away. To me after about 50 yards I no longer like 4 power that much. I think it comes down to a personal preference. I'd personally go with a 3x9 as that way you can have 9 power if you want it or you can just leave it dialed back on 4 power if that's how you like it. Gives you several options.
