The cutting-edge Xtreme Defense Fluid Transfer Monolithic technology is revolutionizing perceptions of self-defense bullets. Similar to the Xtreme Penetrator, its progressive nose geometry ensures deep, direct penetration, all the while generating a permanent wound cavity diameter that surpasses that of most expanding bullets. Moreover, this bullet is crafted from solid copper, capable of overcoming penetration barriers, environmentally friendly and inflicts substantial tissue damage upon impact. Even when passing through obstacles like drywall or heavy clothing before reaching the intended target, the Xtreme Defense remains unaffected by the potentially negative effects experienced by conventional hollow point bullets. The pivotal element lies in the nose design. The Fluid Transfer's radial flutes channel hydraulic energy inward and then, as the energy is constricted, propel it outward, inducing high-pressure spikes that cause significant harm to surrounding tissue. This rapid surge in fluid flow leads to cavitation and extensive tissue damage comparable to the finest hollow points on the market. The outcome of the Xtreme Defense is a permanent wound cavity often two to four times larger than that generated by a flat or round nose bullet, frequently surpassing the dimensions of traditional or solid copper expanding bullets. What you obtain is a self-defense bullet capable of penetrating barriers without deformation or trajectory alteration, while also creating a larger permanent wound cavity and achieving the desired 18 inches of penetration.
