jimmy, you have been given some excellent options....if you really want the 9.3 and are willing to bear the cost..it would be a fun project...at times it has crossed my mind to try these calibers...normally something different doesn't bother me if it is something I really want....If you are a reloader, you can load down the 375 or 338 to equal the smaller cased 9.3.....or just go with a 35 Whelen...game will never tell the diff....and you can get bullets anywhere.,...I would ask my self when was the last time you saw 9.3 on the sporting goods store shelf, or any 366 dia. bullets...since I am retired, I travel quite a bit..usually hit every gunshop, etc. that I come across...I don't when I saw RWS bullets for sale if ever, and I have seen some 9.3 ammo, but it was pretty pricey...all the more you will shoot it it might not be an issue for you.....it is something to consider...with the tight reloading supplies that we face, if I didn't want either of the mags. and wanted a o6 size case, the 35 Whelen would be the way I go....as for Africa, unless you get into some really dangerous game in a fairly pricey country, your .300 will take all the game you will hunt in Africa....been there done that...good luck...decisions like this are fun...
