The body, instead, transmits hydrostatic shock when it is struck by, let's say, high-velocity expanding bullets from handguns. This is the primary mechanism through which high-velocity, expanding bullets achieve their stopping power. Expanding Bullets: Hollow-Points & "Dum-Dums" What do we mean when we say "expanding bullet?" An expanding bullet is most often called a "hollow point." A solid bullet, one with no hole in it, is referred to as a fullmetal 18 www.BulletproofDefenseDVD.com jacketed (FMJ) bullet. Sometimes, it is referred to simply as "ball ammo." Expanding bullets, by contrast, typically have a hole (or an indentation of some other shape) formed in them. When the expanding bullet strikes resistance (human flesh), it expands, deforming around that hole to create a shape like an ashtray. This happens because, as the bullet travels through the body, tissue and fluid are forced into that hole in the bullet, spreading it out and making it bigger as it mushrooms. All of this works because the fluid, which is mostly water, can't be compressed. A common misconception, where hollow-point bullets and stopping power are concerned, is that expanding bullets have better stopping power than FMJ or "ball" ammo because the expended bullet creates a bigger hole (because it is larger in diameter and thus hits more tissue). This is not, in fact, the primary reason why an expanding bullet generally has better stopping power. This is not the central reason an expanding bullet gets greater stopping power though.
