It works fine on three of the Big Five. I was more than prepared to use it on elephant but we didn't find the one we wanted. In full disclosure, however, I used a .270 on the leopard. Dead before he hit the ground. I used that rifle because of the scope on it, not the caliber.
Just curious where you were hunting. I know some African nations allow calibers under .375 (or 9.3mm) but I've never seen a comprehensive list. I personally don't really enjoy shooting anything bigger than a 338 Win Mag., 35 Whelen or 9.3x62, so that's why I ask. I have a nice .338 that I shoot well, and thinking about getting another 35 Whelen.... anyway...
