In my experience there are two "poor man's" African cartridges, the .30-06 and .375 H&H. This is not just my personal experience, but the primary suggestions of the widely varied PH's I have hunted with.
Though even they sometimes disagree. Went on a month-long cull in 2007 that involved 25 hunters, and at least seven PHs. One evening the PHs started drinking beer and disagreed just as much as 24hour.argument.com....
