Normal polymer tips in high BC bullets deform and melt mid-flight. Hornady engineers have found that conventional ballistic tip materials in streamlined, low-drag, high BC bullets melt and deform. Although not a massive issue affecting low-to-moderate BC ballistic tipped varmint and hunting bullets, aerodynamic/ friction heating causes overall BC reduction and degradation of accuracy, particularly at extended ranges (400 yds. +). To combat this effect, Hornady identified a new, heat resistant polymer and used it in the development of the patent pending Heat Shield tip. This revolutionary new proprietary tip creates the optimal meplat (tip) with extraordinarily consistent results from bullet-to-bullet and lot-to-lot. The Heat Shield tip bucks the effects of aerodynamic/ friction heating and maintains its shape to provide a perfect meplat (tip) that is always consistent in shape and size. A streamlined secant ogive, with perfected boat-tail design, plus the highly concentric and symmetrical AMP bullet jackets, combined with the patent pending Heat Shield tip creates a scary accurate, high BC match-grade bullet. ELD-Match bullet BC's are measured with Doppler radar and corrected to standard atmospheric conditions.
