I think that the .416 Remington is a well designed cartridge, with loads of power in a smaller package, but at this stage I'd prefer a Euro gun. I wanted something highly functional and of beauty made to fit me with true artwork fit and finish, but even assuming all things being equal on the firearms front, given the choice I'd still go for the Rigby before the Remington cartridge from a nostalgia perspective as well as the alleged lower pressure envelope within which the Rigby is designed to operate. The Rigby requires a massive action, but I don't see that as a defect. An extra 1/2" of action length shouldn't make a whit of difference to OAL length and a bit of extra weight will probably be a feature to help tame recoil. Short stroking a long action should not be an issue if one practices sufficiently.
