My feelings on a 30-30 is it's a great deer round if you are shooting under 200 yards. You might could stretch a little further with the Hornady ammo they have now. It will do what the majority of hunters need, and in fact be more than what they need. It really is a great deer round.
That being said, if you are somewhere where long range shots are common, it's not the caliber for you.
So it really just depends on the type of hunting you are doing.
