Product Description UNDERWOOD AMMO .223 Remington 62gr Controlled ChaosA(R) Solid Monolithic ammunition was developed to meet the need for a lead-free projectile that delivers extensive wound trauma while minimizing pass-through energy. The bullet is engineered to penetrate to a predetermined depth and then fracture as internal hydraulic pressure exceeds the hoop strength of the nose design, releasing a massive energy spike as particles radiate outward from the initial trajectory path. This sudden energy transfer and resulting temporary cavity are intended to disrupt circulatory and nervous system function with proper shot placement. Built for dependable performance, this load features nickel-plated brass cases for improved feeding and corrosion resistance, flash-suppressed powder for low-light use, and new-production, non-corrosive, boxer-primed, reloadable cases.
