The 450/400 is certainly a great client calibre, but I have to say that if I were buying a double, my personal choice would be an English double (esp in that calibre as there are so many of them out there at good prices.) - If I were to buy an American or European double, it'd have to have a traditional safety and not a cocking lever....... and the Blaser would be my last choice because it's just soooooo fugly.
