Lever guns for Africa?

[Mr. 16 gauge]

I'm curious if anyone had done it or seen it done.....I'm talking medium cartridges such as the .30/30, .32 Win. Special, .35 Remington, .45-70, ect. I realize that these rounds don't have the range as some of the more 'modern' rounds, but it seems to me that if one was patient, and more interested in the stalk than the kill, the guns/cartridges listed would be suitable for some species.
Then again, I know that some countries forbid certain types of rifles, such as sporting or military style autoloaders. I also know that some countries have a minimum energy requirement.
.....and while were on the subject, what about bringing sidearms to Africa, if for no other reason to ward off snakes and two legged varmints?

Since I was a child of the '60s, I guess I watched to much T.V., esp. and old series called "Cowboy in Africa"
