I haven't re-read all the posts, but I don't think anyone has mentioned the superb balance, pointability and handling capabilities of a well made and designed double rifle. Just like a fine side by side shotgun, the design has no peer, except maybe for a well balanced single shot.

No ungainly bolt action even the best designed has anything like balance or the same pointability. Especially in chunky big bore designs.

I'm not surprised the proponents of bolt actions would even think of this because they have never experienced that superb advantage of the double rifle.
