They are not an expanding bullet or a controlled fracturing bullet.
The magic happens with the nose design where the radial flutes force the hydraulic energy inward and then as the energy is restricted, it accelerates outward creating high pressure spikes damaging surrounding tissue. Kind of similar to sticking your thumb over a garden hose. The permanent wound cavity of the XP is from two to four times greater than what a flat or ball nose bullet generates and often larger than traditional expanding bullets. So what you get is exceptional penetration coupled with a larger permanent wound cavity.
