Couple of comments on a typical long-winded Campfire thread involving "calibers" and bullets:
Know an American woman who on her very first big game hunt, a safari in South Africa, killed three animals with one shot each, using a .243 with 85-grain Nosler Partitions. They were an impala (about the size of a typical whitetail buck), and a gemsbok and blue wildebeest, both of which are animals in the 500-600 pound class considered among the hardest to drop of the plains game. In fact many men advise nothing smaller than a .338 Winchester Magnum.
Have killed a bunch of deer from Texas to Montana with various cup-and-core bullets from .243's, and have yet to see one fail to penetrate sufficiently. This includes a 105-grain Speer Hot-Cor than lost its jacket just under the skin of a basic 4x4 Montana buck (the core kept penetrating and dropped him), and doe-culls where the 100-grain "blue box" Federal load broke both shoulders and the spine--and exited.
