I liked the idea of a .450 Marlin in a SA bolt gun the first time I heard about it. If I was chosing between the short .458 and the .450 Marlin in a bolt gun, I'd probably lean toward the .450 Marlin. Cases are good quality and I wouldn't have to spend time with case prep. And, theoretically, the wider belt would have a perceived safety dividend over the std. mag case converted to the short round.
