I have long wanted a 450/400 too, in fact I almost bought a single shot falling block in one thinking I could load lighter .40 bullets for practice and smaller game. Life happened in the interim but you've got me thinking again...my bank account is already cowering in fear!!

Thanks for the youtube links Matt, Krieghoff are an impressive outfit that's for sure! The local Krieghoff dealer has told me the classic doubles now come with ejectors as standard and are included in the base price, which is reassuring to know.
