I've thought about either one of the late-run Winchester Model 95 leverguns in .405 Winchester, or another Ruger #1 in the same chambering. I'd probably go for the former, because I already have a Ruger #1S in .45-70, and it does pretty much everything a .405 will do, albeit with more pain on the shooter's end when I run those 500gr thumper loads throught it.
