I am interested in the 460 S&W mag because of its power AND its ability to use 454's and 45 Colts. I have not been able to find a rifle in 460 (I don't want a single shot). I would really like a carbine length. Could I buy something like this. http://cz-usa.com/products/view/cz-527-carbine/ and rebarrel it to 460? I am concerned because of the high operating pressures 60,000+. Thoughts?
