I too have been toying with this idea. At first blush I thought the 458x1.80 would be slick because it could be made to feed in a bolt gun much more easily than the .460 S&W. The potential problem arises when one considers the possibility of an uninformed individual chambering the cartridge in one of the H&H based smaller bores. I suspect the bolt could close and then it would become very dangerous.
I then revised my thinking to Clint's idea of a short 450 Marlin. Due to the belt shape there would be no danger from chambering in the wrong rifle.
My great concern here is lack of availability of brass. Do I want to dump a significant amount of $ into a custom rifle for which I am unable to purchase or form brass?
Please correct me if I'm wrong, but I thought 450 Marlin brass cannot be formed from anything else; and isn't the cartridge on life support?
