I can't see myself being without a 30/30. I have several other rifles but the Marlin feels the best to me. Rarely I may hunt an area where I may get a shot at 200 yds or better and then I would go with the 270 or 06.
And I havn't even tried the new Hornaday Ballistics. I gave my son a Marlin 336 for christmas and fitted it with scope with peep sights. I personally don't care for the peep sight and for myself I have one scoped and another unscoped. I carry the unscoped with me most every time I go into the swamp and have killed many deer with it just shooting offhand. No other rifle I own feels as balanced and shoulders as well as the Marlin.
