dums dums are bullets with an explosive charge inside the projectile which causes them to explode upon impact. They have been illegal in America for decades. Most light weight jacketed hollow point bullets driven to sufficient velocities (such as the venerable 22/250 for example) will fragmentate upon impact with flesh and bone. This is to prevent over penetration and to ensure a quick clean kill on the small game animal being hunted. The old M16A1 ammo, in fact, was deemed “inhumane” for this reason. The .223 cal bullet would create devastating wound channels in enemy soldiers. The new rounds just penetrate and bounce around a bit.
