Currently having a similar issue. My wife "needs" a deer rifle for her and the little ones, and wants a .243, but doesn't want a scope. So I'm torn between making her happy and getting an Encore in .243, or buying a sensible .30-30 or 7-30 Contender carbine, and throwing on a Williams peep sight on it. At open sight ranges, I think the 7 and .30 have the edge over the .243.
I am a huge fan of 7mm bores in general, but I am leaning toward a .30-30, just for easy to find ammo, and the availability of heavier bullets.
So, I guess I'd agree with your first inclination, and do the .30-30 AI.
