Mrs Blacktailer uses a Kimber Super America in 308. She has used it up to zebra. She lets me borrow it for plains game. Of course when an opportunity presents itself, whatever is in your hands is what to use so I've also taken warthog with the 375. It's handy that they share the M70 type action and safety so there is no need to think about which rifle is being carried at the time.
