The ELD-X™ 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. All manufacturers conventional polymer tips in high BC bullets melt in flight.Hornady® engineers discovered that conventional bullet tip materials in streamlined, high BC bullets melt and deform. Although not a significant issue affecting moderate BC conventional tipped varmint and hunting bullets, aerodynamic heating causes BC reduction and degradation of accuracy, particularly at extended ranges (400 yds +). To counter this effect, Hornady® identified a heat resistant polymer and developed the patent pending Heat Shield™ tip. This revolutionary new tip creates the perfect meplat (tip) with exceptionally consistent results from bullet-to-bullet and lot-to-lot. At conventional range (0-400 yards), the ELD-X bullet is designed to continually expand throughout its penetration path. Upon impact the thin nose section of the bullet peels back and sheds material until it reaches the thick shank of the bullet jacket where the InterLock ring works to keep the core and jacket together. The remaining heavy shank of the bullet continues to drive forward and expand for extremely lethal results.
