The innovative Xtreme Defense Fluid Transfer Monolithic technology is revolutionizing perceptions of self-defense bullets. Just like the Xtreme Penetrator, its advanced nose geometry enables deep, direct penetration while producing a permanent wound cavity diameter exceeding that of most expanding bullets. Moreover, the bullet is composed of solid copper, capable of surmounting penetration barriers, environmentally friendly and inflicts significant tissue damage upon impact. The ability to penetrate obstacles like drywall or heavy clothing before reaching the intended target doesn't yield the potentially negative outcomes on Xtreme Defense as it does on conventional hollow point bullets. The pivotal element is the nose design. The Fluid Transfer's radial flutes channel hydraulic energy inward and as the energy becomes constrained, it propels outward, generating high-pressure spikes that severely impair surrounding tissue. This swift escalation in fluid flow engenders cavitation and extensive tissue damage comparable to the finest hollow points on the market. The outcome of Xtreme Defense results in a permanent wound cavity often two to four times larger than that generated by a flat or round nose bullet, frequently exceeding the dimensions of traditional or solid copper expanding bullets. The outcome is a self-defense bullet adept at penetrating barriers without distortion or altering trajectory, ultimately creating a more extensive permanent wound cavity coupled with the desired 18 inches of penetration.
