The .270, he said, was notorious for letting deer escape, even fatally shot ones, and this was not only his experience but that of the owner of a nearby plantation who had kept careful records over many years.
As it was, I killed four deer, all lung shots, one shot each. One dropped in her tracks; the other three ran 50, 75, and 30 yards, which is about average. I've been hunting whitetails in South Carolina since 1983. In that time I've used everything from a .257 Roberts to a 7mm Weatherby magnum and a great deal in between. I have not seen any evidence that one cartridge killed any quicker than another. My experience is that most deer (probably 70 percent) go on a last mad dash before piling up. I've never seen one go more than 100 yards, and very few have gone that far. I don't believe they run with any destination in mind; they only run.
