A couple of weeks ago I got the idea of rechambering my old 303 Savage. Thanks to the good advice on this board, I decided against it. I now, however, am toying with the idea of rechambering my Marlin 336 in 30-30 to something else. What do you think would work out relatively easily? I got this idea after a guy the other day was telling me how he recently rechambered his Marlin in 35 Rem to a 358 Win.

My initial thoughts here are for a 300 Savage, but I'm not sure how easy that would be. What do you all think?
