Last time I went to Africa I carried a .416 Rigby topped with a 1X6 Leupold, loaded with 400 gr rhino bullets & my trusty .338 WM loaded with 250 Nosler particians & topped with a 3X9 Burris. This time my wife will be hunting and her Winchester Model 70 in .270 will be going so I will probably only take one gun. Animals on my list this time are blue & black wildebeest, nyalla, cape eland, another kudu, & warthog. My guide says take the .338WM & save my shoulder. It's lighter and I KNOW that it will do it's job but the Rigby is a more "traditonal" African gun that does not get used here in the states. The Burris is also illuminated with a red dot. I have A LOT of faith in the old .338. It's wacked a lot of U.S. elk and deer as well as most of what I shot in Africa, moose & caribou. If it were you, what's your advice?
