I don't have one but it's a "make sense" caliber. Marlin hit the nail on the head with this one. For those that don't reload the vaunted 45-70, Marlin allows you to get optimum performance and the 450 is the way to go. Having said that, I've taken my share of deer with an equivalenty loaded 45-70 and am impressed with the performance. There's nothing that walks, crawls, creeps or flies in the lower 48 that I wouldn't take on with it.
