That 45 colt will work ok for small stuff up close. These animals are tough and a marginal hit with marginal power makes for an expensive hike. Bobby hansen will only allow excellent examples or old animals to be taken. He almost would t let me shoot a 32? waterbuck. He knows after a few safaris i am truly happy with old worn animals with character so if theyre available then he will let me take them. He hates african buyers remorse. Every year he gets a couple 60? kudu. He has very very exceptional animals.
