30-30, thats a pea shooter.
I started deer hunting with a .32 Special (30-30 on roids) Then I graduated to a 7MM Weatherby Mag. Nothing like reaching out 5-6 hundred yards if needed.
Oh yeah, I'm a firm believer of the one shot, one kill rule.
Back on topic, One of my friends uses an old Russian Mosin-Nagent rifle which shoots 7.62 X 54, the same round as a AK. It works fine for hunting, other than its a heavy sob.
