The advanced technology of Xtreme Defense Fluid Transfer Monolithic is reshaping perceptions of self-defense bullets. Similar to the Xtreme Penetrator, its innovative nose design enables deep, direct penetration, all while producing a permanent wound cavity diameter that surpasses that of most expanding bullets. Furthermore, the bullet, composed of solid copper, possesses the capability to surmount penetration obstacles, is ecologically friendly and inflicts significant tissue damage upon impact. The act of penetrating barriers like drywall or heavy clothing prior to reaching the intended target doesn't yield the potentially adverse consequences for Xtreme Defense that it does for conventional hollow point bullets. The crux lies in the nose design. The Fluid Transfer's radial flutes channel hydraulic energy inwards and as the energy is constricted, it rapidly propels outward, generating high-pressure spikes that severely damage surrounding tissue. This rapid surge in fluid flow induces cavitation and extensive tissue damage comparable to the finest hollow points available. The outcome of Xtreme Defense is a permanent wound cavity often two to four times larger than that of a flat or round nose bullet, frequently exceeding the dimensions of traditional or solid copper expanding bullets. The result is a self-defense bullet capable of penetrating barriers without distortion or trajectory alteration, while producing a larger permanent wound cavity combined with the desired 18 inches of penetration.
