If your looking for a factory load, I'd go with the Remington 170gr. Round nose Soft point. I hunter with this round for years before I went to a .30/06. I have killed 4 bears with this round, plus a Brown Bear when I lived in Alaska. All one round kills.
As far as the LeverEvolution ammo, Erin (Quick Draw) uses it in her 30-30 savage and like the way they shoot.
