Before I got a dedicated varmint rifle, I tried quite a few light bullets in my .30-06, including 55 gr Accelerators, Hornady 100 gr bullets, a few different 110 gr., and 130 gr. hollow point Speer bullets. The 130s were the only ones that I could get to shoot decent groups (by decent I mean 2" - 3", which obviously isn't very good). I had way better luck with a rifle chambered for a varmint round. Most .30-06 rifles do better with the heavier bullets they were designed for. I'd go with the .223, or something similar.
