BTW big assumptions there. In the end most or many gunmakers make what their client wants. Good ones will advise strongly against some of the requests but in the end, its the clients money being spent on what they want.

Some gunmakers may actually say NO, others will do it because the client demands it.

Lots of doubles have been made for rimless cartridges. Few for stupid over the top pressure big bore cartridges.

But hey, if knowledgeable guys on NE think a .460 Wby Mag is a good chambering say so, and then explain why they think so. Perhaps with examples of similar rifles and chamberings they actually own which are equivalent hot big bores. Would be interesting to hear about.

(Ash, btw I wouldn't think a .416 Rigby is a very good choice for a double rifle, let along a Wby ... )
