I have never been to Africa, do shoot a 45-70, but I believe when going away to hunt its better to look at what has worked for the PH's and their advice on it. I love my 45-120 andhave some serious loads worked up in it on a No-1, but its still behind my 450Nitro.. To me hunting Cape buffaloe with a 45-70, is like me going to work with out the bullet proof vest I'm issued
