The advanced technology of the Xtreme Defense Fluid Transfer Monolithic is revolutionizing perceptions of self-defense bullets. Much like the Xtreme Penetrator, its innovative nose geometry enables profound and direct penetration while generating a permanent wound cavity diameter that surpasses that of the majority of expanding bullets. Moreover, the bullet is constructed from solid copper, capable of surmounting barriers to penetration, environmentally friendly and inflicts substantial tissue damage upon impact. The act of penetrating obstacles such as drywall or heavy clothing prior to reaching the intended target doesn't yield the potentially adverse consequences for Xtreme Defense as it does for conventional hollow point bullets. The crux lies in the nose design. The Fluid Transfer's radial flutes channel hydraulic energy inward and as the energy becomes restricted, it rapidly accelerates outward, generating high-pressure spikes that inflict severe damage to surrounding tissue. This rapid surge in fluid flow induces cavitation and extensive tissue damage akin to the finest hollow points available. The result 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 outcome is a self-defense bullet capable of penetrating barriers without deformation or changes in trajectory, while producing a larger permanent wound cavity combined with the desired 18 inches of penetration.
