I have a 35 Marlin that my son killed his first deer with. I have mostly hunted with a 270. I want to get a deer with the 35.

But...at a local gun shop there is a 336 30/30 that is in excellent shape that I can get for under $200.

Would this be practical? Are these two close enuff not to make a difference?

I may get the 30/30 just so I have one in my collection.
