Black Hills Ammunition has added two new performance loadings, a 5.56mm 77 grain and a .308 175 grain for 2014. Both new loads feature the newly developed Sierra Tipped MatchKing™ bullets. The sleek polymer tip on these new MatchKings increases the Ballistic Coefficient (BC) to an incredible .420 on the 5.56mm 77 grain and .535 on the .308 175 grain. These impressive BCs provide improved external ballistics with less drop and wind drift. In addition, the new tip design improves terminal performance by providing more uniform on-target performance compared to standard open tip match bullets.
