The odd thing about anchoring via a bigger and better cartridge/bullet is that applied horsepower doesn’t work as we might think. Bullets from shoulder-fired rifles, handguns, or even slug guns do not kill by blunt force trauma. Getting hit by a 500-grain bullet carrying 5,000 ft-lbs. of kinetic energy is not like getting hit by a 2,000-pound truck going 40 mph. The bumper, grill, and fenders of the truck spread energy over a wide area. This transfers the energy broadly across the animal, crushing muscles, bones, and internal organs. But, as any highway patrol officer can tell you, even a badly mangled animal can still cling to life long after the hit.
