Well in advance of any journey to Africa (or name your destination), train mightily with your boots and your rifle both.
It simply will not do, to be on the other side of the globe and way out in the bush, when you discover that your boots hurt your feet and / or your rifle does not function properly.

I own or have owned at least a half dozen CZ Model 550 rifles, in calibers 6.5x55, through .500 Jeffery.
Only the .500 gave me feeding problems (built by CZ's so called "Custom Shop").
When I called them to describe that, not only did my rifle refuse to feed at all from the magazine but, likewise when carefully using four hands, to coax a live factory (present day Kynoch) round from the magazine, I found the chamber was too short to allow said round to fully chamber.
Likewise, my rifle mis-behaved exactly the same way with A-Zoom brand dummy rounds.
In other words, when one guy would hold the rifle firmly and the other guy (me) would wiggle the round with one hand, as I simultaneously pushed the bolt forward, until the cartridge would finally go into position (extractor in the groove and bullet / cartridge almost completely into the chamber, the bolt would not close completely).
Whomever answered the phone, wanted to respectfully argue with me that Kynoch ammunition and A-Zoom dummy rounds are both out of spec.
And therefore, I should have a company known as: "Superior Ammunition" load my cartridges.
When I told him that a friend (our fellow forum member, Cal Pappas) owns an original Pre-War, August Schuler built .500 Jeffery Mauser and that it feeds / chambers my cartridges like greased lightening, and furthermore, if anyone would have known what the chamber specs for this cartridge are, surely it would be the firm that invented the jolly cartridge to begin with, he had the nerve to stick to his original story.

"Custom Shop" ....... right.

Nervous that this same fellow might be the one pounding and grinding on my rifle, I elected to take it to a local Gunsmith here in Anchorage (Andy Hawk) who, I knew to have fixed the exact same issue on a pretty much identical rifle to mine (except for the fact that it was a .505 Gibbs caliber).
Andy fixed it in short order and I now find no issue with my .500 except, now that the dust has settled, I sometimes wish I had saved the over $3,000.us dollars it cost and put that money into my piggy bank, toward another Safari.
Oh well, for the time being, I plan to just keep it and gamble that CZ will eventually stop chambering .500 Jeffery caliber then, perhaps I can sell it or trade it for something close to the amount I have in it.

Anyone looking for a very powerful bolt action rifle to hunt elephant, hippo on land or even buffalo, I otherwise highly recommend the, "5 in the magazine / true magnum sized action" CZ 550 rifle in .458 Lott.
(I have one of those as well, LOL).

Be all of that as it may, I also like very much the controlled round feed version Model-70 Winchester.
One of these (in .375 H&H for instance), would be an excellent choice for today's Africa - albeit in my very limited experiences, over to the world's best big game hunting grounds.
My only complaints (3 total and they are very small ones) are that:
A.
The Winchester action is just a wee bit too small for large bore cartridges.
Even in .300 H&H / .375 H&H, it has to be tweaked and cut a little to accept these plus, I think this size action leaves the Model 70 as only a 3 shot rifle, when chambered in those two dreaded H&H calibers.
Not that I've ever run any bolt action rifle dry when bagging my biltong but, if I'm using a repeater for dangerous critters, I'd prefer the two extra shots of the CZ.
B.
The bolt handle needs to be bent straight down on dangerous game caliber rifles, instead of bent garishly backwards, to point directly at the shooter's knuckle (on their trigger finger).
C. It's very small and petty, not to mention that it is my personal character flaw but, I also think the deeper magazine of the CZ looks more like an "African dangerous game rifle"whereas, the Model 70 looks more like a "deer rifle", I know ...... you can say it, I have issues.
