10 million $ farm (in today's money) quote from Jim Carmichael, shooting editor for Outdoor life for 20+ years, author of Complete Book of the Rifle, holder of many rifle shooting records and big game records in Africa, N America. He also bet $50,000 (in today's money) that he could do so with no more than 2 shots per animal. under condition of fair chase, too. So much for "needing" a 338, .45-70, etc.
