The ELD-X (Extremely Low Drag - expanding) bullet is a technologically advanced, match accurate, all-range hunting bullet featuring highest-in-class ballistic coefficients and consistent, controlled expansion at all practical hunting distances. Features: Best-in-class - verified by Doppler radar, the Heat Shield tip is immune to the effects of aerodynamic heating and retains its shape to maintain the highest-in-class BC over its entire trajectory Match accurate hunting bullet - streamlined secant ogive with optimum boattail design + highly concentric AMP bullet jackets + Heat Shield tip combine for radically superior aerodynamic efficiency Devastating conventional range performance - with high velocity 0 to 400 yd impact, the bullet continually expands throughout its penetration path The thick shank of the jacket and high Interlock ring keep the core and jacket together providing 50 to 60% weight retention Upon low-velocity 400+ yd impacts, the Heat Shield tip drives backward into the bullet to initiate expansion Exhibiting conventional expansion with a large mushroom and 85 to 90% retained weight the bullet provides deep penetration and large wound cavities Twist rate - 1:8-1/2 inches
