As said before, my experience with the .338-06 (very similar) was that range had to be limited on big PG in Africa. 'Made a perfect shot on a blue wildebeest at 275 yds and we watched it run toward Zambia! Others at 150 yds or less worked out ok (Kudu ran 500 yards, Eland 150, Zebra about the same, dainty Nyala straight down.) I upgraded to my 264 WSM on that hunt and brought the .338 A-Sq next trip! I am definitely a fan of Ruark's sage advice on Using More Gun in Africa. They are not elk or deer! Uncle Roy is made for Africa as well (in med calibers-overbore for DG calibers). I would like to have a .358 NM (or STW!) With them you can push heavy, highest SD bullets where they need to be, with more V and E. 'Friend wants to bring his 35W Ackley-Improved to Africa. It needs all it can get, but should work out ok! Beautiful old gun from Paul Jaeger.
