There are two types of ammunition: hard, full-metal-jacketed bullets that go straight through the body and cause comparatively modest damage, and soft ammunition that expands in the body on impact and does enormous damage. There is a vast difference between hitting a person with a bullet that’s nine millimetres in diameter and a bullet that expands to a couple of centimetres or more in diameter. The latter type is called hunting ammunition, and its objective is to cause massive bleeding. It is considered more humane when hunting moose, since the aim is to put down the prey as quickly and painlessly as possible. But hunting ammunition is forbidden for use in war by international law, because a soldier hit by an expanding bullet almost always dies, no matter where the point of entry.
