Good luck on your quest and please DM me if you want some outfitter suggestions. I have been lucky enough to hunt water buff and scrub bull in Oz, feral cattle in Hawaii, and more recently Cape buffalo in South Africa. Used all sorts of calibers and loads and can't say any failed from the 9.3x74, to 300 Mag, 470 NE and the 375 Ruger. Big question for you being where you are is ammo availability/cost. I stopped in a gunshop in Sydney last year and I was impressed with the number of double rifles that were for sale. So large caliber ammo seems readily available (I didn't ask the cost). Then again I killed two scrub bull in 2016 in the NT with a 9.3x74 and it did the job. A 375 Ruger is not something I would have ever considered but after using it in South African this past summer on two buffalo, I have to say I was impressed. Did the job in one shot each and had very mild recoil. Problem is with rifle maker availability and even worse that no one makes the ammo but for Hornady. As for scope, whether a proper scope or red dot reflex sight, the red dot feature is a must for me. Can't go wrong with a Leupold.I hope to hunt Buffalo at some point.
My question is at what would be your preferred minimum calibre for any sort of Buffalo or Bovine hunting whether you have it or would choose it for the purpose?
Elaborate on the cartridge , rifle , scope etc if you like I’m interested in what works or what you would choose if selecting something fit for purpose
