Marlin 336 in .30-30
Preferably one before they were bought by Remington. Don't be at all afraid to buy used if the stock is acceptably clean, these guns will last forever.
I killed my first deer with my grandfathers Marlin 336 .35 remington.
The main things to look for are the stock and the action. The action should ideally be pretty smooth. If the gun has any sort of age to it, the insides of it probably need some cleaning. Old oil just kind gums them up and they don't operate as smoothly as they can. Our 336 .30-30 works like brand new after I took it apart and cleaned all the parts.
