Some years ago I bought a Baikal 9.3x74R O/U. It's somewhat agricultural but has given me a taste for doubles and for the calibre. What I want to do is upgrade to a better quality rifle in SxS with ejectors. From a paper ballistics point of view, the 9.3x73R and the .375 Flanged Magnum are very similar. Although I haven't seen much info on heavy for calibre projectiles. Any thoughts or experience would be appreciated. For me one issue is the availability of ammunition and components. In my country I know I can reasonably easily get 9.3x74R cases, but haven't seen .375 Flanged Magnum around (until now I haven't been looking). .375 projectiles are much more widely available and in a greater variety of weights and construction. What I don't know is how easily available factory ammo would be in Africa for each of these.
