Right, I'd like Ahmed/C to tell us what are the planned uses of each?
What he plans to hunt with each first or generally? OK lets put aside problems with travel at the moment, and assume the world has returned to normal.

Water buffalo I assume is one beast. Saltwater crocodiles for the .300, .303 and .375? How about elephant for the .600? Surely? Magpie geese for the 10-bore smoothbore? And pigs and maybe buffalof rot eh rifled choke 10-bore? Roos for the 5.6?

I am guessing of course, and would love to know, what is planned for this impressive battery. Thanks C if you can comment?

PS I am willing to be a gun bearer! You can only carry one at a time, so eight others are needed and perhaps three or four ammo bearers!
