Every manufacturer has their own chart with their own guidelines depending on bullet weight and type for each category. For a newb shooter,it can be very confusing. The OP's .308Win is an awesome round as long as the bullet weight and type will cause maximum penetration and rapid expansion. I recommend 160gr. PSP and up for large North American game with accurate shot placement in the vitals to ensure a quick,clean kill.
