.220 Swift

Bullet Recommendations for Africa
Varmints Frangible fourth generation
Antelope Fifth (bonded core) or seventh generation (solid expansion bi-metal) bullets
African Game Weight Recommendation
≤ 75-lb (≤ 35-kg)
Most Suitable African Species (assuming legality)
Varmints : Aardwolf, civet, honey badger, black-back jackal, side-striped jackal, vervet monkey, otter, serval  and the wild dog
Cats : Cheetah, caracal (lynx)
Antelope : Common duiker, red duiker, grey rhebok, Cape grysbok, Sharpe’€™s grysbok, klipspringer, oribi and steenbok. Given premium bullets and proper shot placement it can be stretched for use on antbear, blesbok, bontebok, brown hyena, Arabian oryx, springbok, common reedbuck and impala. There are way more suitable cartridges for the latter species though.
