The Xtreme Defense Fluid Transfer Monolithic, powered by advanced technology, is revolutionizing perceptions of self-defense bullets. Much like the Xtreme Penetrator, its innovative nose geometry enables deep, direct penetration while yielding a permanent wound cavity diameter surpassing that of typical expanding bullets. Furthermore, the bullet's solid copper construction empowers it to conquer penetration obstacles, maintaining eco-friendliness while inflicting substantial tissue damage upon impact. Unlike conventional hollow point bullets, the Xtreme Defense remains unhampered by barriers like drywall or heavy clothing, sidestepping the potential adverse effects before reaching the intended target. The cornerstone of its efficacy lies within the nose design. The Fluid Transfer's radial flutes channel hydraulic energy inwards and upon restriction, it rapidly accelerates outward, generating intense pressure spikes that inflict considerable harm to surrounding tissue. This swift surge in fluid flow creates cavitation and extensive tissue damage, akin to the effects of top-tier hollow points in the market. The outcome is an Xtreme Defense bullet that forges a permanent wound cavity two to four times larger than that produced by flat or round nose bullets, often surpassing the dimensions of traditional or solid copper expanding bullets. What one acquires is a self-defense bullet capable of piercing barriers without distortion or alterations in trajectory, engendering an expanded permanent wound cavity alongside the desired 18 inches of penetration.
