Whitey, someone else may be able to confirm that there were double rifles made on the Robust action. Entirely possible I suppose, although I'd guess they'd likely be the less potent European calibers rather than something for large and dangerous game somewhere like Africa. (Sounds like that would work OK for you.) And what you may also have heard is that some Robusts have one rifled barrel. That part is certainly true, but in most (all?) cases, the rifling is not for a rifle bullet or slug, but rather to disperse the shot charge--a pattern wider than cylinder, favored by many European woodcock hunters.
