In reading many of these posts regarding double rifles, folks have made references regarding the availablility of ammo in certain calibers. For example, it seems that 375 Flanged is not too common, but 9.3x74R is much more common.

This brings up the question: which calibers are most common for purchasing loaded ammo? I am speaking in terms of traditional rimmed double rifle ammo larger than 35 caliber. I am not speaking of belted or rimless cartridges, as that stuff really is quite common.
