Yes, the 30-30 is always getting slammed. But in this case, I'd opt for the 30-06 too. Mainly because your shoots are going to be over 150yds. The 30-30 is good with-in its range. Where I hunt, 50yds is a long shoot. So the 30-30 is a perfect choice, but in your case it is not.

Guns cause crime, like flies cause garbage.
