The Federal Blue Box stuff is good ammo. You'll do fine. In case you run up on any, though, keep a lookout for Remington 170 grain Core Lokt HP's. They are pure deer cyanide.
I have a buddy who is a very good rifleman. He tells me every so often that he has never owned a lever action rifle.
I just don't see how an American can reach the age of 40 without once owning a Lever Action rifle.
Oh well, I'll keep him in the will.
Back to the point. Congratulations on your new rifle. I've owned both Winchesters and Marlins, but if I am honest, I have to say that I always preferred the Marlin.
You did good to pick up the 30-30. Ammo is SO much easier to come by.
