Corelockts sometimes shed their cores, sometimes they don't. Sometimes when they shed their cores, they drop a deer in their tracks. I don't want to use a bullet where I know maybe it will shed its core, maybe not. What is most important to me is a hit that will be lethal. If it drops right there or runs 100 yards is of little matter. In Mike's example, even though it ran 100 yards, it was a dead deer. With it being hit in two lungs, it would have been dead without the follow-up shot.
