Hornady TAP 308 Winchester Ammo 155 Grain ELD Match ammo review offers the following information; Hornady 308 WIN 155 gr. ELD Match TAP Precision® ammunition was designed as an improvement on the 155 grain A-MAX TAP Precision load by incorporating the new ELD Match bullet. The 155 gr. ELD Match bullet with Heat Shield tip delivers the excellent terminal performance TAP Precision is known for, but features a resilient, heat resistant polymer tip that improves the ballistic coefficient, resulting in higher impact velocities, less drop, less wind drift, and more energy on target.
