You got yourself one terrific rifle!! I started out with a Marlin 336 in 30/30. I ended getting a Marlin 336 in 35 Rem.
Still have it and still hunt with it at least one of my hunts every year. I go between my Winchester 70 in 30.06 and my Marlin 35.
I mix in a couple of others.
Congrats, it will last a lifetime.
