westley476' - it's hard to disagree.
The reason I threw the 340 in the mix is because my days of hunting in Africa these days is mostly for plains game, which I very much enjoy. And, although I'm a 378 fan, my straight shooting and well worn 340 will knock down anything I choose to go after in Africa or here in North America.
Besides, for the really big stuff I've knocked down in Africa over the years I've used other more traditional time honored and bigger bore favorites of mine.
In any event, I agree that the 378 Wby is a tremendous cartridge and like you I also HATE BRAKES.
Good huntin' to you.
