Here's how the mighty 458 Winchester Magnum stacks up against the venerable 45-70 Government cartridge, especially with regards to how both perform in Africa. In this episode, we discuss the history, design characteristics, and performance specs of each round. We'll also discuss the pros and cons of each one, a few stories involving hunting with the 45-70 and 458 Win Mag, and I'll also discuss the results of some of my investigations regarding tacking myths and misconceptions involving both rounds as well.
