A 30.06 would work but I'd rather have less kick, I think. I'd also like to practice from time to time, so, lower cost ammo would be nice.
Saying this points you right at the .308 without a doubt. Ammo costs are significantly lower in that caliber. Kick is less.
A guy told me about a newer 30-30 cartridge that is lethal on much longer shots. I don't recall the name of it but I do see one by Hornady.
Hornaday Leverevolution ammo. With a scope on your 30-30, you'd be good to 200 yards, perhaps a bit more. That ammo gets good reviews.
