Rifles and Calibres for African Game

The calibre argument is the oldest one in hunting and mostly a distraction. African game is not bulletproof; it is tough, often shot at moderate range off sticks, and rewards good bullets placed correctly far more than magnum velocity. Here is what actually works, and where the law removes your choice.
In this guide
Plains game: one rifle does everything
Anything from .270 Winchester through .308, .30-06 and the 7mm and .300 magnums will handle the full plains-game list from springbok to kudu and eland. The .30-06 remains the most sensible single answer on the continent: ammunition is available everywhere, recoil is manageable enough to shoot well, and with a premium 180-grain bullet it is enough rifle for eland. If you already shoot a .308 or .270 well, bring that rather than buying something bigger you will flinch with.
Bullets matter more than calibre
Use a premium controlled-expansion or bonded bullet — the kind that holds together through heavy shoulder bone on a blue wildebeest. Standard cup-and-core hunting bullets built for whitetail can come apart on African game. Bring forty to sixty rounds of one load, sighted in before you travel, and do not switch loads mid-hunt.
Dangerous game and the legal minimum
For buffalo, elephant, lion, leopard and hippo most African countries set a legal minimum of .375 calibre — in practice the .375 H&H, which remains the most useful dangerous-game rifle ever built. Heavier options from .416 through .470 come into their own on elephant and on follow-ups in thick cover. Solids for elephant, premium softs for buffalo, and enough practice that you can put the first one in the right place under pressure.
Optics and sighting in
A robust 3-9x or 2.5-10x scope covers everything; big-magnification target optics are a liability in thorn. Sight in to be roughly 2.5cm high at 100 metres, which puts you dead on around 180 metres — beyond most shots you will take. Check zero on the range the day you arrive: air travel and rough transfers move scopes, and every camp expects you to confirm before hunting.
Practise off sticks — this is the real advice
Almost every African shot is taken standing off three-legged shooting sticks, a position most visiting hunters have never used. Buy a set, practise until you can hold steadily and break a clean shot inside ten seconds at 100 and 150 metres, and you will out-hunt someone with a far more expensive rifle who only ever shoots prone off a bench.
