The advanced technology of the Xtreme Defense Fluid Transfer Monolithic is reshaping perceptions of self-defense bullets. Just like the Xtreme Penetrator, its progressive nose design allows for profound, linear penetration while generating a permanent wound cavity diameter surpassing that of most expanding bullets. Additionally, the bullet's solid copper composition enables it to surmount penetration barriers, making it environmentally friendly and causing significant tissue damage upon impact. The ability to penetrate obstacles like drywall or heavy clothing before reaching the intended target doesn't carry 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 direct hydraulic energy inwards and as the energy becomes constrained, it propels outwards, creating high-pressure spikes that inflict severe damage on surrounding tissue. This rapid surge in fluid flow induces cavitation and extensive tissue damage comparable to the best hollow points on the market. The outcome of Xtreme Defense is a permanent wound cavity often two to four times larger than what a flat or round nose bullet generates, frequently surpassing the dimensions of traditional or solid copper expanding bullets. The result is a self-defense bullet adept at penetrating barriers without deformation or altering trajectory, ultimately generating a more extensive permanent wound cavity paired with the desired 18 inches of penetration.
