The Xtreme Defense Fluid Transfer Monolithic is revolutionizing perceptions of self-defense bullets through advanced technology. Just like the Xtreme Penetrator, its innovative nose geometry enables deep, straight penetration and generates a permanent wound cavity diameter surpassing that of typical expanding bullets. Furthermore, the bullet's solid copper composition ensures it can surmount penetration barriers, while remaining environmentally friendly and inflicting substantial tissue damage upon impact. Unlike conventional hollow point bullets, the Xtreme Defense remains unaffected by barriers such as drywall or heavy clothing, negating the potential negative impacts before reaching the target. The crux lies in the nose design itself. Utilizing the Fluid Transfer's radial flutes, hydraulic energy is directed inward and upon constriction, it rapidly accelerates outward, producing high-pressure spikes that inflict severe damage to surrounding tissue. This swift surge in fluid flow results in cavitation and extensive tissue damage, comparable to the effects of top-tier hollow points in the market. The outcome is an Xtreme Defense bullet that generates 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. The end result is a self-defense bullet that effectively penetrates barriers without distortion or changes in trajectory, creating an enlarged permanent wound cavity combined with the desired 18 inches of penetration.
