ronlaughlin, wasn't that a .45caliber bullet? 300gr in a .45 would have to have a lot of length. That would give it a pretty high sectional density. Not to mention, though they give an okay idea, just a water jug test really isn't that much of test for tough hide and heavy boned animals such as a black bear. Fair test for whitetail but people seem to be under the false impression that a whitetail bullet is going to perform just as well on a black bear. Black bear have near twice the bone density of whitetail and near 4 times the fur and hide thickness. At least the fully grown adults do anyway. Those 338 plats are just copper washed lead. Not a bullet I would put my life on when facing and animal that could turn and chew me up before I got reloaded. I myself want something that will bust through bone and hide and anchor that animal.
